While the species concept has remained constant, the generic placement is not agreed upon. Originally described as a species of Echinomastus by Hester (03), this view is also held by Zimmerman (04), Glass and Foster (05), and Backeberg (06). Weniger placed the species in Echinocactus (07), an invalid combination; Benson transferred the species to Neolloydia (08), without explanation. Synomyms for the common name of Lloyd's mariposa cactus include; golf ball cactus and mariposa cactus. The type specimen (J.P. Hester accession # 236, earlier described as "H-5") is located in the Dudley Herbarium (#271943) (02). Other specimens may be found at the following herbaria: ASU, CAS, MO, POM, RSA, SRSC, UNM, and US (04). Descriptions, photographs, and/or drawings are found in various references: (01,02,03,07,09,10,11). The photograph used in the original description of Echinomastus warnockii (08) illustrated misidentified plants of mariposensis. Immature plants appear at first glance to be a different species from old adults due to the very different morphology between immatures and old adults (04). Taxonomy - 2

HABITAT ASSOCIATIONS

HABITAT - TERRESTRIAL TERRESTRIAL LAND USE - Residential Transportation, communications, and Util Shrub and Brush Rangeland COMMENTS ON HABITAT ASSOCIATIONS - Neolloydia mariposensis is an element of the Chihuahuan Desert flora. The habitat area is very open with a few shrubs, but a great diversity of small perennial xerophytes (04). Some of the components of the community are Larrea divaricata, Agave lecheguilla, Euphorbia antisiphilitica, Jatropha dioica, Hechtia scariosa, Fouquieria splendens, Yucca sp., Opuntia phaeacantha var. discata, O. leptocaulis, O. rufida, Coryphantha strobiliformis var. strobiliformis, Echinocereus stramineus, E. dasyacanthus, Mammillaria lasiacantha, M. pottsii, Ariocarpus fissuratus and Epithelantha bokei (01,04). In at least two sites N. mariposensis grows with Coryphantha ramillosa (04). Neolloydia mariposensis is found on hills and the lower slopes of mesas (01). The soil is alkaline and very rocky, composed primarily of crumbling limestone gravel (01). Occurring in full sun in patches of limestone chips, the reflection from the whitish rocks raises the heat and light radiation surrounding N. Mariposensis to extremes (01). The mean annual temperature is about 64 degrees F, and the mean annual total precipitation ranges from 10 inches on the western edge of the range to 14 inches on the eastern edge (12). The primary land use in the area is rangeland. Populations occur in the vicinity of Lejitas and Terlingua, TX, near old quicksilver mines (with associated buildings) and along highways and roads (with associated fences, and utility poles) in both Texas and Mexico.

LIFE HISTORY

HABIT: Succulent (01,02,03,04,05,06,07,08,09,10,11). LIFE CYCLE: Perennial (01,02,03,04,07,10,11). TYPE OF REPRODUCTION: Sexual (01,04). REPRODUCTIVE PHENOLOGY: Germination, leafing and budding dates are unknown. Anthesis occurs in March or May (01,03,04). Fruiting occurs in April or mid- summer and seed/fruit dispersal dates are unknown (01,03,04). Although Weniger (01) states that flowering occurs from April to May and that fruits mature in mid-summer, Hester (03) reports flowering in the first part of March and fruit maturing in the latter part of April. Field work in the Big Bend area supports Hester's observations, not Weniger's (04). SEX OR SPORE STATUS: Monoclinous (01,02,03,07,10,11). POLLINATION, SPORE AND SEED DISSEMINATION: Pollen dissemination agents are insects, the exact taxa is unknown (01). The seed dissemination agents are probably gravity, raindrop-spatters and ants (04). The fruits are dry and the seeds are released into the spines at the stem apex (04). SEED BIOLOGY: The only information available indicates that the seeds germinate "easily" and "grow well" in cultivation (01). POPULATION BIOLOGY: Neolloydia mariposensis is scattered fairly evenly over its habitat (01). Some areas were commercially striped of all visible small cacti, causing the population to decline (01,04). Although Neolloydia mariposensis appears to have returned in these areas (01), seedlings which were too small to have been collected in years past have only recently reached sufficient size to be conspicuous (04). However, the populations have not yet returned to normal (04). ECOLOGICAL/EDAPHIC FACTORS: Perhaps because of its small size (even in adulthood), Neolloydia mariposensis is confined to areas having a very stable surface; either rock crevices or desert pavement of limestone chips (04). The soil is alkaline and very rocky, composed primarily of crumbling limestone gravel (01). Occurring on hills and lower mesa slopes in full sun in patches of limestone gravel, the reflection from the whitish rocks raises the heat and light radiation surrounding Neolloydia mariposensis to extremes (01). The elevation varies from around 2500 to 3500 feet (01). The mean annual temperature is about Life History - 1 (DRAFT) - Life History Species CACTUS, MARIPOSA, LLOYD'S Species Id ESIS702017 Date 13 MAR 96 64 degrees F, and the mean annual total precipitation ranges from 10 inches on the western edge of the range to 14 inches on the eastern edge (12). Geologic formations in the area where Neolloydia mariposensis occurs are various Quaternary deposits, the Chisos Formation (conglomerate, sandstone, mudstone, tuff, and igneous rocks: Tertiary), and various Cretaceous, primarily limestone formations: Santa Elena, Sue Peaks, Del Carmen, Telephone Canyon, Boquillas, Glen Rose, Del Rio Clay, Aguja (clay, sandstone, and lignite), Javelina (clay and sandstone), and Pen (mostly clay and some sand) (14). Aridisols and entisols are the soil orders in the area of occurrence of Neolloydia mariposensis (15). At a finer level, the soil series are; Chamberino, Lajitas, Lozier, Mariscal, Pantera, Solis, Tornillo and Upton-Nickel (15). These vary from very shallow to deep soils and are well drained and gravelly in some layers (15). TROPHIC STATUS: Phototrophic (02,07,10,11). CHARACTERISTIC DOMINANCE: Component (01,04). Neolloydia mariposensis is widely scattered in its habitat (01,04). COMMUNITY ECOLOGY: Neolloydia mariposensis is a minor part of the Chihuahuan Desert, xeromorphic shrub, a stable community (13). Even though the cactus has been commercially stripped from some areas, the species has partially recovered (01,04). SPECIES INTERRELATIONSHIPS: According to Warnock, the "petals" are eaten by rodents and birds (09). OTHER LIFE HISTORY DESCRIPTORS: Although Neolloydia mariposensis tends to be ecologically segregated from N. warnockii, a closely related species, they overlap slightly at least near Lajitas (04). Seedlings grown from field- collected Neolloydia mariposensis seeds include a small number of N. mariposensis x N. warnockii hybrids (04). However, no hybrids have been observed in the wild (04).

Probably off-road vehicles are operated in the habitat also. Former mercury mining activity in the Terlingua-Lajitas area posed another threat to the habitat (01). The populations at Dove Mountain, Big Canyon and the hills near Reagan Canyon, are subject to disturbance by livestock, although presently the impact is probably slight (04). The Big Bend National Park populations are threatened by camping, hiking, and trail and road maintenance. Perhaps the major threat is commercial exploitation and collection. The cactus is a rare show specimen and collector's item (01). A possible future threat would be the use of herbicides in range management practices by private landowners (01). Management Practices - 1 (DRAFT) - Management Practices Species CACTUS, MARIPOSA, LLOYD'S Species Id ESIS702017 Date 13 MAR 96 UNAPPROVED PLAN: U.S. Fish and Wildlife Service. 1986. Agency Review Draft: Recovery Plan for the Lloyd's Mariposa Cactus. U.S. Fish and Wildlife Service, Albuquerque, New Mexico. 35 pp. The prime objective of the Recovery Plan is to manage and protect Lloyd's mariposa cactus and its essential habitat so that healthy populations can be in their natural habitat at a level that will allow the species to be delisted. The two known populations occurs in Big Bend National Park and on private land, mostly owned by the Lajitas Museum and Desert Garden. Removal of threats to Lloyd's mariposa cactus populations in both locations are recommened through: 1) Enforcement of existing collecting and trade regulations under the Endangered Species Act, CITES, the Lacey Act and Texas State Law. 2) Cooperative agreements with both organizations. 3) Development of monitoring studies. 4) Development and implementation of habitat management plans. Ecological and population biology studies of Lloyd's mariposa cactus are needed. Information required for better management include the determination of; 1) Soil needs, 2) water needs, 3) the role of animals in seed dispersal, 4) microhabitat factors involved in seedling establishment, 5) pollinators, and 6) population dynamics of each known Lloyd's mariposa cactus population. Environmental parameters defining and restricting Lloyd's mariposa cactus's distribution need to be determined. This information could then be used to inventory a sufficient proportion of suitable habitat to make an accurate estimate of range and habitat actually occupied and the number of plants in the wild. This new information should be used to update the management plans recommended above. Other management needs addressed by the Recovery Plan include: 1) Development of a comprehensive trade management plan for all cacti. 2) Development of propagation techniques to provide nursery stocks and seeds to reduce collecting pressure. 3) Development of public awareness, appreciation and support for the preservation of Lloyd's mariposa cactus. Additional considerations for the recovery of this species include management plans or agreements which address the control of herbicide use, grazing, development, off-road vehicle use and other recreational activities which may adversely impact a population of the Lloyd's mariposa cactus.
