LIN. SYST. Monadclphia, Dec&ndria. Calyx turbinately- 

 tubular, 5-cleft ; the lobes lanceolate-subulate and acute, the 

 two superior ones rather remote. Petals about equal, at length 

 separating elastically. Vexillum roundish. Wings oblong. Keel 

 composed of 2 petals, straight and acute. Stamens 10, mona- 

 delplious. Ovary linear, terete. Style ascending. Stigma ca- 

 pitate. Legume compressed, 2-valved, oblong-linear, beaked, 

 by the acuminated style, having 2 nerves near the superior su- 

 ture, and furnished with cellular substance between the seeds. 

 Seeds 7-8, obovate or truncate, compressed. Endopleura tumid, 

 appearing like albumen. Cotyledons elliptic, flat, thickish, and 

 foliaceous. Primordial leaves simple and ovate. An erect herb, 

 with subulate stipulas, pinnately trifoliate leaves, ovate, exsti- 

 pellate, glaucous, denticulated leaflets, and axillary, short, ra- 

 ivmes of small, erect, blue flowers. The hairs on the plant 

 are fixed by their centre, as in Indigofera. The genus appears 

 to be allied to Dolichos or Canavalia on the one hand and to 

 Lupinus, Psoralea or Indigofera on the other.

Cult. Tin's plant is not worth cultivating, except in botanical 

 gardens. The seeds of it should be sown in a pot filled with 

 loam and sand, and placed in a hot-bed, and when the plants 

 have grown 2 or 3 inches high, they should be planted singly 

 into separate pots, and replaced again in the hot-bed, where 

 they will ripen their seed. Some of the plants may be planted 

 out in the open border, in a sheltered situation.

 with the others at the base. Legume length of calyx, valveless, 

 1-seeded, sometimes ending in a beak. Shrubs or herbs, usually
