FUNTUMIA 



FURCR^A 



1305 



FUNTUMIA {Fu7ilum is one of the vernacular names 

 of F. elastica). Apocynaces. Three trees, sometimes 

 very tall, of Trop. Afr., formerly placed in Kickxia, one 

 of them being a rubber tree. F. elastica, Stapf, reaches 

 100 ft., with a cyhndric trunk and pale spotted bark: 

 Ivs. oblong or lance-oblong, undulate; fls. white or 

 yellowish in short-peduncled many-fid. dense cymes, 

 the corolla-tube constricted above the base, the lobes 

 oblong and obtuse; stamens inserted well down in the 

 corolla-tube; disk 5-parted: follicles oblong-clavate, 

 woody. Offered in Eu.; yields the Lagos caoutchouc. 



FURCRjEA (Ant. Frangois de Fourcroy, 1755-1809, 

 chemist). Syn., Fourcroya, Fourcrosa, Furcroya, Fur- 

 croea. Amaryllidacese. Succulent desert plants from 

 tropical America. 



Some with spiny fohage like Agave, others with 

 minutely toothed margins Uke Beschorneria. They 

 occasionally bear immense loose panicles of greenish 

 white fls., suggesting those of Yucca fdameniosa, which 

 are known to every plant-lover of the N. The perianth 

 of Furcrsea is whitish and wheel-shaped; in Agave 

 greenish yellow, funnel-shaped. The filaments in 

 Furcrsea have a cushion-Uke sweUing at the base, 

 which is absent from Agave. 



Furcra;a is cultivated much in the same way as 

 Agave, except that the furcreas are given more heat 

 and water. F. gigantca has a very pretty variegated 

 form, which makes a useful pot-plant. 



As a rule, furcreas bear fruit not more than once, 

 and then die without producing suckers. However, 

 they produce while in flower an immense number of 

 bulbels, which may be used for propagation. It is 

 impossible to say at what size or age the plants will 

 bloom. Grown in pots, they may take a century. On 

 the other hand, plants from bulbels have been known 

 to flower at three years. Seeding is usually rare.

A. Lvs. Tough-margined but not toothed, glaucous, striate- 

 Toughened beneath: infl. pubescent: pedicels short. 

 Serrulate. 



1. longaeva, Karw. & Zucc. Slender unbranched 

 tree, up to 50 ft. : lvs. rigidly outcurving, narrowly 

 lanceolate, gradually acute, concave, 3-6 x 60 in. : 

 infl. 15 ft., broadly conical, short-stalked; fls. 134-1}^

 Leop. Carol. 16, pt. 2:48. M.D.G. 26, p. 10. Bateman, 

 Orchid, of Mex. & Guat. Vignette to pi. 16. B.M. 5519, 

 (habit). Herbert, Amaryll., pi. 34. — A similar if sepa- 

 rable species is reported for Bolivia. The most remark- 

 able drac»noid tree, flowering when extremely old, 

 and then dying, like others of its genus. 



2. Roezlii, Andre (Agave argyrophylla, A. Toncliana, 

 Beschorneria floribunda, Lilia rcgia, Lilium rigium, 

 Roezlia regia, R. reg'uia, Yiicca argyrsea, Y. argyrophylla, 

 Y. Parmentieri, Y. Toneliana, Hort.). Trunk becoming 6 

 ft. or more: lvs. rather flaccidly spreading, lanceolate, 

 acute, concave or plicate, 3-5x50 in.: infl. 10-15 ft., 

 pubescent, the moderately broad panicle short-.stalked; 

 fls. 1 ^4 in. ; ovary and segm. about equal : caps, ellipsoidal, 

 scarcely stipitate: freely bulbiferous, the bulbels 

 elongated. S. Mex. R.H. 1887, p. 353. B.M. 5519 (as 

 to details) ; 7170 (as F. Bedinghausii) . G.C. III. 9, p. 489; 



36, p. 45; 46, p. 340. — The common plant grown along 

 the Riviera, often as F. longaeva, but more commonly as 

 F. Bedinghausii, with which the synonymy is confused. 



3. Bedinghausii, Koch (Beschorneria muUiflbra, 

 Hort. Yiicca Pringlei, Greenm. Roezlia or Yucca bulbi- 

 fera, Hort.). Trunk scarcely 3 ft.: lvs. rather rigidly 

 outcurving, lanceolate, acute, rather flat, 2-3 x 18-24 

 in.: infl. 10-15 ft., the rather narrow panicle httle 

 longer than the scape; fls. 1)2 in.; ovary and segm. 

 about equal: caps, broadly oblong, abruptly stipitate; 

 seeds moderate (li-% x 3-2 in-): freely bulbiferous, the 

 bulbels ovoid. Cent. Mex. B.H. 13, p. 327. Ann. 

 Jard. Buitenzorg. II. Suppl. 3:44. G.W. 7, p. 101. 



AA. Lvs. smooth-margined, typically toothed, usually 



green, not striate. Edfurcr.ea.

 cubensis, Jacq. A. bulhlfera, Sahn? A. hexapetala, 

 Jacq. A. mexicana. Lam. A. odorata, Pers). Nearly 

 trunkless: lvs. narrowly lanceolate, spreading, smooth,

 23-I in. apart: infl. 10-15 ft., long-stalked, nearly 

 glabrous; fls. 2 in.; ovary fusiform, about equaling the 

 segm.: caps, small, broad, stipitate; seeds small 

 QA A in-): bulbels ovoid. Cuba and Haiti. Jacq., 

 Stirp. Amer. : 175. Ann. Jard. Buitenzorg. II. Suppl. 

 3:40. — As badly confused as Agave americana 

 and actually rarely seen in gardens: apparently the 

 original henequen of early writers on the W. Indies, 

 its fiber called cabuya. A related Yucatan species, 

 the cahum, with less lanceolate lvs. and ovary exceed- 

 ing the perianth, is F. Cahum, Trel., Ann. Jard. Buiten- 

 zorg. II. Suppl. 3:39. 



BB. Prickles large or prominently raised and rather dis- 

 tant, curved, — suppressed in certain forms. 



c. Shape of lvs. oblong-lanceolate, large.

 ing, concave, smooth, about 3 x 60 in. ; teeth Kin- 

 long, 3^-1} sin. apart: infl. 15-20 ft., rather short- 

 stalked, pubescent; fls. 2I4 in.; ovary 1 in.; segm. IJ-^

 (depauperate). Related species are: F. elegans, Tod. 

 of Guiana, with lvs. 5 in. wide with hooked black- 

 ening teeth K-Jsin. long and 1?5 in. apart, glabrous 

 long-stalked infl., and leafy-tipped bulbels. Hort.

 F. andina, Trel. (F. Dcledevdntii, and F. altissima, 

 Hort.?), of E. Peru, with nearly as large and distant 

 teeth, short-stalked infl., cuboid caps, and conical- 

 ovoid bulbels. Ceara or Pcrnambuco hemp is ascribed 

 to F. agavephylla, Brot. (F. cubensis. Mart. Agave
