previously described Dcsmoschinensis, Lour.; U. Desmos, 

 Dunal, is D. cochinchinensis, Lour, (see Desmos, in Vol. 

 II). Belonging to other genera are Dunal's U. uncindta, 

 which is the fragrant Artobotrys odoratissimus of the 

 Orient; I', riolacea, which is undoubtedly a species of 

 carrion fls., Sapranthus, closely allied to Sapranthus 

 nicaraguensis; U. penduliflora, which is the aromatic 

 ear-flower, or xochinacaztli, of the Aztecs (Cymbopeta- 

 lum penduliflorum, Baill.); and his U. acutiflora and U. 

 xylopimdes are both synonyms of the spicy Xylopia 

 grandiflora, St. Hil. B. L. Robinson's U. bibracteata, the 

 fragrant "flor de guineo," which ranges from Nicaragua 

 to Panama, and his U. panamensis have been set apart 

 by the writer under the generic name of Desmopsis. 

 The latter has recently been rediscovered by Henry 

 Pittier at its type locality in the Canal Zone. Both of 

 the latter species are figured bv the writer in the Bull. 

 Torr. Bot. Club, vol. 43, pp. 183-93 (1916). See also

URARIA (Greek oura, tail, referring to bracts). 

 Lfguminbsse. Subshrubby perennials, adapted to the 

 wannhouse; 1 species has been 

 tried in S. Fla. Lvs. pinnately 3- 

 rarely 5-7-foliate or the lower 

 rarely all 1-foliate; Ifts. usually 

 large, stipellate; stipules free, 

 acuminate: fls. purplish or yellow- 

 ish, arranged in terminal hirsute 

 racemes, which are sometimes elon- 

 gated, sometimes dense and spike- 

 like; calyx-lobes subulate acumi- 

 nate, 2 upper teeth short, 3 lower 

 usually elongated; standard broad; 

 wings adhering to the obtuse keel; 

 stamens diadelphous; ovary sessile 

 or stipitate, few-ovuled: pod of 2- 

 6 small, turgid, 1-seeded indehis- 

 cent joints, often placed face to 

 face. About 17 species, Trop. Asia. 

 Afr., and Austral. 



crinita, Desv. Erect little- 

 branched subshrubby perennial, 

 3-6 ft. high, distinguished from 

 other species by having its upper 

 Ivs. composed of 3-7 oblong Ifts. 

 and pedicels clothed with long bristles: Ifts. 4-6 x 

 in.: racemes dense, 1 ft. long, 1-1 J^ in. thick; standard 

 ovate, violet-purple within, pale blue outside; wings 

 pinkish. Bengal to Assam, eastward through Burma 

 to China, south to Malacca and the Malay Isls. to 

 Timor Laut. but not Austral, and not indigenous in 

 Ceylon. B.M. 7377. Sometimes the raceme has 200 

 or more fls., each of which is Y-i\n.. long.

URBINIA (named for Dr. Manuel Urbina). Crassula- 

 ce&. Perennial succulent herbs, caulescent or acaules- 

 cent : Ivs. closely imbricated, thick and rigid: infl. rather 

 few-fld., cymose: calyx small, 5-lobed, lobes ovate to 

 lanceolate, equal or unequal, much shorter than the 

 corolla which is somewhat cone-shaped, lobes united at 

 base into a tube; stamens 10, borne on the corolla; 

 carpels 5. Three or 4 species, Mex. See also Cotyledon, 

 Vol. II, p. 868. U. obsciira, Rose. Caulescent: at.

 flattened, somewhat rounded at base: fl.-sts. thickish, 

 with many narrow Ivs.: infl. a 2-branched raceme: fls. 

 about 10; calyx-teeth lanceolate; corolla about Via*.. 

 long, bright rose below, lobes slightly spreading, yellow. 

 Habitat unknown. U. Purpusii, Rose. Acaulescent : Ivs. 

 forming a very compact rosette, broadly ovate, acumi- 

 nate, 1 y in. long and nearly as broad at the base, gla- 



brous, mottled with brown: flowering st. reddish, nearly 

 1 ft. high, bearing numerous small, ovate, appressed 

 Ivs.: infl. about 6-fld., in a raceme: sepals green, ovate, 

 acute; corolla somewhat urn-shaped, pinkish outside, 

 pale yellow inside, petals acute. S. Mex.

URCEOCHARIS (from the genera Urceolina and 

 Eucharis). Amaryllidaceae. A hybrid between Urceo- 

 lina pendula and Eucharis grandiflora, or in gardener's 

 language Urceolina aurea and Eucharis amazonica. A 

 flower of the hybrid and of each of its parents is shown 

 in Fig. 3886. It is a tender winter-blooming bulbous 

 plant with broad Ivs. a foot long and half as wide, and 

 large white bell-shaped 6-lobed fls. a dozen or so in an 

 umbel, and each 2 in. across. The hybrid gets its white 

 color from Eucharis, the fls. of Urceolina being yellow. 

 The shape of its fl. is so singular a mixture of the two 

 as to be very different in appearance from either. The 

 hybrid lacks the beautiful staminal cup of Eucharis, 

 and has a distinctly bell-shaped perianth. The showy 

 part of Urceolina is the urn-shaped portion of the fl., 

 the spreading tips being very short. The perianth of 

 Eucharis is funnelform, the spreading portion being 

 large and showy. The perianth-tube and ovary of the 



3886. At the left, Eucharis grandiflora; middle, Urceolina pendula; at the right, the hybrid 

 Urceocharis Clibranii. (All half sice.) 



hybrid are like those of Urceolina, the ovary being 

 deeply 3-lobed instead of globose as in Eucharis. The 

 pedicels are ascending, as in Eucharis, not pendulous as 

 in Urceolina. The appendages at the base of the 

 stamens are more distinctly marked than in either of 

 the parents. This bigeneric hybrid was intro. to the 

 trade under the name of Eucharis Clibranii, but the 

 changes wrought in the structure of the fl. by the cross 

 are so great that Dr. Masters was justified in giving the 

 plant a new genus. 



Clibranii, Mast. (Eucharis CTibranii, Hort.). Tender 

 bulbous hybrid of Urceolina pendula and Eucharis 

 grandiflora, with petioled Ivs. 1 x 1^ ft. and umbels of 

 white bell-shaped 6-lobed fls. each 2 in. across and a 

 dozen in an umbel, anthers depauperate. Blooms in 

 early winter. For cult., see Urceolina. G.C. III. 12:215; 

 26:251. Gn. 44, p. 459. G.M. 35:790. G. 16:450. 

 Intro, about 1892 by Messrs. Clibran, Oldfield Nurseries, 

 Altrincham, England. 



edentata, C. H. Wright. From Peru, described from 

 a plant that bloomed in the establishment of Sander & 

 Sons, supposed to be a natural hybrid between an 

 Urceolina and a Eucharis; differs from U. Clibranii in 

 having no teeth on the corona between the filaments.
