LEGUMINOS^E. CCCIX. CRAFORDIA. CCCX. AMMODENDRON-. CCCXI. LACARA. CCCXII. HARPALYCE, &c. 467 



Many-spiked Varennea. Shrub 1 to 2 feet. 



Cult. See Sarcddum for culture and propagation, p. 466. 



CCCIX. CRAFO'RDIA (named apparently after some bota- 

 nist or horticulturist of the name of Craford). Rafin. spech. 1. 

 p. 159. D. C. prod. 2. p. 522. 



LIN. SYST. Diadelphia, Decdndria. Calyx cumpanulate, 5- 

 cleft ; segments nearly equal. Corolla papilionaceous, with a 

 large reflexed vexillum, adpressed wings, which are auricled at 

 the base, and an obtuse keel, which is longer than the wings. 

 Stamens 10, diadelphous. Ovary linear. Style filiform ; stigma 

 dot-formed, glabrous. Legume usually 2-seeded, linear, toru- 

 lose, striated. Seed oblong- reniform. A twining plant, with 

 impari- pinnate leaves ; leaflets oblong, mucronate, sessile. Pe- 

 duncles longer than the leaves, somewhat spicate ; bracteas sca- 

 rious, subulate, permanent, ciliated. Flowers white. This 

 genus is allied to Galega and Colutea according to the author, 

 but from both and from Tephrosia it differs in the 2-seeded 

 legume.

 on the banks of the river Susquehannah. 



Bracteate Crafordia. PI. tw. 



Cult. Peat or vegetable earth is a good soil for this plant, 

 and cuttings will be easily rooted. 



CCCX. AMMODE'NDRON (from apuot, ammos, sand, and 

 cti'tyov, dendron, a tree ; habitation of the shrub). Fisch. in 

 D. C. legum. mem. xvi. prod. 2. p. 528. Led. fl. alt. 2. p. 110.

 wings and dipetalous keel equal and connivent. Stamens 10, 

 distinct. Legume flat, membranous, 1 -seeded from abortion, 

 marginated by a wing, samaroid. Seed reniform, compressed. 

 A small, neat, silky shrub, having the petioles hardening into 

 spines. Leaves bifoliate ; leaflets lanceolate. Flowers purple, 

 disposed in racemes. This genus is closely allied to Hallmo- 

 dcn/Iron, which genus it ought to have followed in the body of the 

 order.

 salt fields in the desert of Soongaria, and at the river Bekun.

 entd. 3. p. 56. D. C. prod. 2. p. 528. 



LIN. SYST. Decdndria, Monogtjnia. Calyx campanulate, 5- 

 toothed. Petals 5, unequal, unguiculate, nerved, concave. Sta- 

 mens 10, free, inserted in the bottom of the calyx, pilose at the 

 base, longer than the petals. Anthers versatile. Capsule ? 

 pilose. A shrub, with alternate, simple, quite entire, petiolate, 

 coriaceous, unequal, triple-nerved leaves, and axillary racemes 

 of flowers. The fruit of this genus is unknown. 



1 L. TRIPLINE'RVIA (Spreng. 1. c.) J; . S. Native of Brazil. 

 Leaves a span long, and a hand in breadth. 



Triple-nerved Lacara. Shrub.

CCCXIII. HARPA'LYCE (from Harpalyce in mythology, 

 the daughter of Clymenus, remarkable for her beauty ; in refer- 

 ence to the beauty of the plant). Moc. et Sesse, fl. mex. icon, 

 ined. ex D. C. prod. 2. p. 528. 



LIN. SYST. Monadelphia, Decdndria. Calyx bilabiate, deci- 

 duous, bibracteolate at the base, both lips lanceolate, acuminated, 



and entire. Corolla papilionaceous, with an obovate vexillum, 

 auricled wings, and a 2-edged, elongated, acuminated, rather 

 twisted keel. Stamens 10, monadelphous. Style filiform, in- 

 curved with the carina. Legume compressed, flat, narrow at 

 the base, ovate-oblong at the apex, 4-5-seeded, mucronate by 

 the style. An erect herb, suffrutescent at the base, with impari- 

 pinnate leaves, and axillary peduncles, which are longer than the 

 leaves, bearing racemes of large red flowers. This genus ap- 

 pears to be allied to Phaseulus from the bibracteolate calyx, and 

 the incurved carina, but differs particularly from that genus in 

 the leaves being impari-pinnate, but in consequence of the le- 

 gume being 2-seeded, and the leaves being impari-pinnate, the 

 genus is probably allied to Astragalus, but the calyx is very 

 distinct.

 New Spain, in the hot regions. Astragalus carndsus, Moc. et 

 Sesse, fl, mex. ined.

CCCXIII. DIPLOPRION(from c<.K\<me,diploos, double, and 

 irpiiov, prion, a saw ; in reference to the legume being ser- 

 rated on all sides). Viv. fl. lib. p. 48. t. 19. f. 2. D. C. prod.

LIN. SYST. Monadelphia, Decdndria. Calyx tubular, 5-tooth- 

 ed. Corolla papilionaceous. Filaments 10, connected. Le- 

 gume 1-celled, flat, many-seeded, spirally involute, serrated on 

 both margins. An annual hairy herb, 2-3 inches long, with pe- 

 tiolate trifoliate leaves, ovate lanceolate stipulas, and axillary 

 peduncles, bearing each a head of yellow flowers. This genus 

 is allied to Mcdicago according to the habit, but from the legume 

 it appears to be more nearly allied to Siserrula, but it is not 

 sufficiently known. 



1 D. MEDICAGINOIDES (Viv. 1. c.) O H. Native of Libya, in 

 the great Syrtis, in fields. 



Medick-like Diploprion. PI. 2 to 3 inches.

 open border in a dry warm situation.

 tor of the government mines of Columbia ; native of Arequipa, in 

 Peru). H. B. et Kunth, nov. gen. amer. 7. p. 2C6. D. C. prod. 

 2. p. 524. 



LIN. SYST. unknown. Flowers unknown. Legume stipitate, 

 obliquely-elliptic, compressed, mucronate, chartaceous, 2-valved, 

 1 -seeded. Seed oblong-reniform, fixed to the lower part of the 

 pod, covered with friable white substance. Cotyledons thick. 

 Radicle small, situated beneath the apex of the embryo, pointing 

 to the bottom. An unarmed tree, with impari-pinnate leaves, 

 bearing 1-3 pairs of coriaceous leaflets, having the petiole winged. 

 Peduncles usually terminal. Perhaps this genus belongs to tribe 

 Geoffrece, near Andira, or perhaps to tribe Cassiece, near Co- 

 paifera.
