peat, and sand. Those marked frame require the protection of a 

 frame or greenhouse in winter. The seeds of the annual species 

 only require to be sown in the open border early in spring. 

 Those species belonging to divisions Alopecuroidei, Traga- 

 cdnthee, Incani, Dissitiflori, and Onobrycholdei are the most 

 worthy of cultivation.

LIN. SYST. Diadelphia, Decdndria. Calyx bibracteate at the

Tribe III. 



HEDYSA'REjE (plants agreeing with Hedysarum in some 

 important characters). D. C. legum. mem. vii. prod. 2. p. 307. 

 Embryo with the radicle bent back upon the edge of the cotyle- 

 dons (f. 21. e.f.). Corolla papilionaceous (f. 42. &.). Stamens 

 rarely free, but usually monadelphous (f. 43. e.) or diadelphous, 

 9 joined together, and one free (f. 44. rf.), or 5 in each bundle. 

 Legumes dividing transversely into 1 -seeded cells or joints (f. 

 41. e.). Cotyledons flat, changing into leaves at the time of ger- 

 mination. This tribe is very natural, and easily distinguished 

 from the rest by the legumes being divided transversely into 

 joints, unless in the following genera, Onobrychis, Eleiotis, and 

 Lespedeza, which have only 1 -celled, 1 -seeded legumes, and in 

 a few others, which have the legumes divided into transverse 

 cells from membranous or spongy dissepiments, but not separat- 

 ing into joints. 



SUBTRIBE I. CORONILLE^; (plants agreeing with Coronilla in 

 some characters). D. C. prod. 2. p. 308. Flowers disposed in 

 umbels (f. 41. b. f. 42. b.). Legumes terete (f. 41. e.) or com- 

 pressed. Stamens diadelphous, 9 joined and 1 free.

 pion, and ovpa, oura, a tail ; in reference to the twisted form of 

 the legumes). Lin. gen. 876. Goert. fruct. 2. t. 155. D. C. prod.

LIN. SYST. Diadelphia, Decdndria. Calyx 5-cleft, with equal 

 acute lobes. Corolla with a 2-edged keel. Stamens diadel- 

 phous, the 5 longest dilated a little under the anthers. Ovary 

 sulcated. Style filiform, acute. Legume revolute, rather spiral, 

 constantly of 3-6 1-seeded joints, which are furrowed length- 

 wise, with the nerves usually prickly or muricated. Embryo 

 replicate. Cotyledons linear. Annual herbs, with membranous 

 linear-lanceolate stipulas, simple entire leaves, which taper into 

 the petiole, axillary 1-4-flowered peduncles, which are longer 

 than the leaves, and yellow, rarely purple flowers.
