 The Orders and Tribes which I adopt are : — 



I. SILICULOSiE. 



1. Thlaspide^. Angustisept; the partition between the cells being on the shorter diameter 

 of the compressed pouch. Cotyledons accumbent ; i. e., the Radicle bent along the edges 

 of the cotyledoiis. Gen. 35-38. 



3. LfiPiBiNEiE. Like the preceding, except that the cotyledons are incumbent; i. e., the 

 Radicle is turned up on the back of one of the cotyledons. Gen. 39-45. 



3. ALYSSiNEiE. Latisept; the 'partition between the cells being on the longer diameter of the 

 compressed pouch. Cotyledons accumbent. Gen. 46-57. 



4. Cameline^. Differs from the last in having the cotyledons incumbent. Gen. 58. 



5. VELLEiE. Latisept. Cotyledons folded laterally. Gen. 59, 60. 



6. Nucamentace^. Silicle falling off entire ! Gen. 61-67. 



II. SILIQUOS^. 



7. LomentacEjE. Seeds placed one above another ; but the Pod not spKtting longitudinally, 



and without a vertical dissepiment. Gen. 68-73. 



8. Beassice^. Cotyledons folded. Gen. 73-78. 



9. SiSYMBEiE^. Cotyledons incumbent. Gen. 79-86. 

 10. AEABiDEiE. Cotyledons accumbent. Gen. 87-95. 



I. SILICULOSiE. 

 Tribe 1. TELASPIDEM. 



35. BISCUTELLA. Silicle of 2 circles, which fall off separately, each containing one 

 seed. L. more or less divided, generally rough. Ft. yellow, p. 14. 



36. IBEKIS. Silicle oval (inversely heart-shaped, Sm.). FU. not toothed. Two outer Pet. 

 largest. Cells one-seeded. Sep. alike. Fl. white or purplish, p. 14. 



37. TEESDALIA. (Silicle inversely heart-shaped, Sm.) Longer Eil. each with a scale at 

 the base. Seeds 3 in each cell. Small plants, with pinnate L., nearly naked stems, and minute 

 white Fl, p. 15. 



38. THLASPI. Silicle inversely heart-shaped. Valves with a bordered keel. Seeds 2 or 

 more in each cell. Sep. alike. Fl. small, white. Fr. in lax racemes, p. 15. 



Tribe II. LEPIBINEM 



39. HTJTCHINSIA. Silicle nearly entire. Valves keeled, but without a border. Pil. 

 simple. Seeds 2-4 in each cell. Some of the species appear to have incumbent cotyledons. 

 p. 16. 



40. CAPSELLA. Silicle inversely triangular. Valves not bordered. Fil. without teeth. 

 Seeds numerous, p. 16.
