Benson KINGDOM: Plant GROUP: Angiosperm DIVISION: Magnoliophyta CLASS: Magnoliopsida ORDER: Caryophyllales FAMILY: Cactaceae Cereus eriophorus var. fragrans (Fragrant prickly-apple cactus) is a columnar cactus with fluted cane-like stems 1-5 meters long. The longer stems lean or sprawl over neighboring shrubs or trees. The cylindrical stems are 2.5-5.0 centimeters in diameter and very spiny. The nocturnal flowers are white or pink, scented, and 7.5-10 centimeters in diameter. The orange-red fruits are 5-6 centimeters long. This species is not easily distinguished from the somewhat more widespread Cereus gracilis, which has shorter spines and differently shaped fruit (01). The fragrant prickly-apple cactus grows to 4.5 meters tall, with coarse fibrous roots. The stems are erect, reclining, or clambering, stout and succulent, prominently ten-to-twelve-ridged, the ridges more or less depressed between the areoles, the grooves rather deep and sharp. The areoles are about 20 millimeters apart, each with a dense tuft of very short hairs on the upper side. The spines are acicular, Taxonomy - 1 (DRAFT) - Taxonomy Species CACTUS, PRICKLY-APPLE, FRAGRANT Species Id ESIS704029 Date 13 MAR 96 9-13 in each areole, mostly grayish and yellowish at the tip, one at each areole longer than the others, mostly 2-4 centimeters long. The young buds are copiously white-hairy. The buds about to expand are 12-20 centimeters long. The flowers are nocturnal, very showy and fragrant. Hypanthium is light green, longer than the flower-limb, slender-funnelform, scarcely ridged, the swollen base bearing subulate or lanceolate-subulate separated scales, with long, white, lax hairs protruding from beneath them. The scales of the tubular part of the hypanthium are few and remote, subulate, slenderly acuminate, not turgid, with a tuft of long white hairs in each axil. The sepals are narrowly linear, slenderly acuminate, the outer ones are green, the inner ones with white midribs or the innermost nearly white. The corolla is white or pinkish, about 9-11.5 centimeters wide, rotate-campanulate. The petals are numerous, spatulate, with the broadened upper part unevenly toothed, acuminate, sometimes caudate- acuminate. The stamens are very numerous, not exceeding the petals. The filaments are filiform, white or nearly white. The anthers are yellow. The style is greatly elongate. The stigmas are mostly 9 to 12. The berry is obovoid, 5-6 centimeters in diameter, dull red, with tufts of long white hairs persistent with the scale bases. The seeds are black, about 3 millimeters long, somewhat swollen at the base, obscurely crested at the apex, finely pitted (02, as quoted in 06, with minor changes in orthography). Cereus eriophorus var. fragrans was discovered by John K. Small of the New York Botanical Garden on the eastern coast of Florida in St. Lucie County. He named it Harrisia fragrans (02), placing it in a genus that is now estimated to number about 20 species in "Florida, West Indies, and South America from Brazil to Argentina east of the Andes" (03, p.20). The genus is placed in the tribe Hylocereeae (03). Lyman Benson made Harrisia fragrans a variety of Cereus eriophora, a Cuban species: the new name was Cereus eriophorus var. fragrans (Small) L. Benson (04). Benson's delimitation of the genus Cereus is not generally accepted (see 05, for example), so the taxon could be formally reassigned to the genus Harrisia. The type specimens of Cereus eriophorus var. fragrans are from Florida: St. Lucie County, 20 Dec. 1917, J.K. Small. The holotype is at the New York Botanical Garden. Isotypes are at the Gray Herbarium (Harvard Univ.) and at the U.S. National Herbarium. Other specimens include a topotype: Florida. St. Lucie Co., Benson & Benson 15375) at the Rancho Santa Ana Botanical Garden, Pomona, CA. A specimen from Brevard County, islands east of Malabar, 3 Nov. 1903, is at the New York Botanical Garden.

HABITAT ASSOCIATIONS

HABITAT - TERRESTRIAL TERRESTRIAL LAND USE - Residential Mixed Forest Land COMMENTS ON HABITAT ASSOCIATIONS - Cereus eriophorus var. fragrans is known to occur on dry sand soil in the remnants of what appear to have been thickets of cabbage palmetto (Sabal palmetto), sand live oak (Quercus geminata), Chapman oak (Quercus chapmanii), myrtle oak (Quercus myrtifolia), red bay (Persea borbonia), and stopper (Eugenia uniflora), with vines including greenbriar (Smilax laurifolia), grape (Vitis rotundifolia), and the parasitic love vine (Cassytha filiformis). Conradina grandiflora, a candidate for Federal listing, occurred at one site (06). Prickly-pear cacti (Opuntia) are strongly associated with populations of Cereus (07). The sites have mostly been altered by bulldozing, leaving sandy fields with Muhlenbergia grass and Polygonella fimrbriata (a wireweed). Since the sites are in an area that has had houses since the late nineteenth century, it is possible that other human activities, perhaps including firewood gathering, have affected the areas. Brazilian pepper (Schinus terebinthifolius) and lantana (Lantana camara) are present in the area, but invasion by exotic plants does not seem to be a principal threat to the cactus.

LIFE HISTORY

HABIT: Succulent (02,06). LIFE CYCLE: Perennial (06). TYPE OF REPRODUCTION: Sexual, vegetative (03, 06). Reproduces via seeds (06); stems may root where they lie on the ground, as with many other cacti (03,06). REPRODUCTIVE PHENOLOGY: Flowering May (07), Fruiting May-October (06,07). SEX OR SPORE STATUS: Monoclinous. Flowers perfect; plant hermaphroditic/monoclinous (02). POLLINATION, SPORE AND SEED DISSEMINATION: Night-flowering (02). Moth pollination? SEED BIOLOGY: The seeds are possibly eaten and excreted by birds; the tendency of the cactus to occur within the driplines of shrubs and trees suggests this (07). POPULATION BIOLOGY: The largest known population is on a sand ridge where much of the vegetation was bulldozed. The population contains numerous plants 10 inches or taller that appear to be seedlings. Most plants bear several fruit. Some stems in this population appear to have died due to rot or decay; the fruits appear to attract birds and some stems have wounds apparently made by woodpeckers (08). ECOLOGICAL/EDAPHIC FACTORS: Xeric sands. Appears to be a plant of dry, excessively drained sites, as are other members of the genus Harrisia (05). TROPHIC STATUS: Phototrophic. CHARACTERISTIC DOMINANCE: Component of community, never dominant (06). COMMUNITY ECOLOGY: The sites occupied by Cereus eriophorus var. fragrans are mostly disturbed oak-red bay scrub on dry sand dunes. The cactus appears to establish itself readily in the disturbed areas (08). More information may become available in the future.

MANAGEMENT PRACTICES

Possibly illegal take (poaching) (06). The plant was collected on islands in the Indian River in 1906 (see above); it is possible that the spread of Casuarina (Australian pine) has deleteriously altered some habitat--this is speculative. UNAPPROVED PLAN: U.S. Fish and Wildlife Service. 1987. Technical Review Draft. Recovery Plan for Fragrant Prickly-apple Cactus. U.S. Fish and Wildlife Service, Jacksonville Field Office, Jacksonville, Florida. (manuscript). A draft recovery plan has been prepared for the fragrant prickly apple cactus (Cereus eriophorus var. fragrans). The following actions are recommended for recovery of the cactus: 1. Protect habitat of the cactus by inventorying known populations; arranging for protection of land through cooperative agreements with landowners, lease agreements, and acquisition by conservation organizations or government agencies; managing protected sites to maintain the cactus populations by discouraging poachers, preventing entry by vehicles, and otherwise preventing disturbance; monitoring Management Practices - 1 (DRAFT) - Management Practices Species CACTUS, PRICKLY-APPLE, FRAGRANT Species Id ESIS704029 Date 13 MAR 96 the condition of each protected population regularly. Monitoring methods must be able to detect changes in the size of a population. Photography should be appropriate. Search for additional populations. 2. Augment the existing populations of Cereus eriophorus var. fragrans by encouraging spontaneous expansion of protected populations, and by introducing the cactus to appropriate unoccupied, protected sites. 3. Enforce available protective legislation. The Fish and Wildlife Service should initiate Section 7 consultation when applicable. Enforce take and trade prohibitions of state and Federal law. Utilize available regional and county planning programs to encourage protection of habitat suitable for the cactus. 4. Provide public information about Cereus eriophorus var. fragrans to landowners, governmental agencies, and conservation organizations. 5. Conserve germplasm through establishment of permanent garden collections under the auspices of the Center for Plant Conservation; place seed in long-term storage. Management Practices - 2
