276 MEXICO. [Capparidea. 



2. C. Caraccasana. De Cand. Syst. 1. p. 142 ; Schlecht. in Linn. 5. p. 209. — C. Cari- 

 pensis. H. B. K. Nov. Gen. 5. p. 29 ; De Cand. Prod. I. p. 4. 



The only specimen in the collection appears to be the extremity of a branch, and has all the leaves tri- 

 foliolate, 



Ord. II. DILLENIACEZE. DC. 



1. Curatella Americana. Linn. ; De Cand. Prod. 1. p. 70. 



This is not noticed by Schlechtendal as a Mexican plant. 



I. Tetracera volubilis. Linn.; II. B. K. Nov. Gen. 5. p. 50; De Cand. Prod. 1. p. 67. 



Ord. III. MENISPERMACEiE. Juss. 

 1. Cissampelos Pareira. Linn. — Schlecht. in Linn. 5. p. 211, et 6. p. 418. 



Both the male and female plants are in the collection ; the upper as well as under side of the leaves are 

 densely clothed with a harsh tawny tomentum. 



Ord. IV. FUMARIACEiE. DC. 

 1. Corydalis (Bulbocapnos) ambigua. Cham, et Schl. ? — Hab. Talisco. 



There is only the fragment of a raceme, without stem or leaves. Another specimen is in the Mexican 

 collection, but as it belongs to what we have noticed among the Loo Choo plants as Corydalis racemosa, 

 we presume it was only placed here by mistake. 



Ord. V. CRUCIFERiE. Juss. 



1. Senebiera Mexicana ; foliis linearibus acutis integris vel apice tridentatis, racemo 

 laxifloro, siliculis subcompressis didymis sublaevibus. 



This we do not find noticed by authors, although we already possess it in our herbarium, also from Mexico, 

 where, particularly on the west side, it is probably not uncommon. It has quite a different appearance from 

 the <S. didyma of Europe. We may here remark, that S. serrata, Poir., from Montevideo, and a new species, 

 (foliis angustissime linearibus integerrimis) from Tweedie, found in North Patagonia, form a new section of 

 the genus, which may be characterized thus : Silicula nec apice emarginata nec dorso cristata : fiores subum- 

 bellati. 



1. Lepidium virginicum. L. — De Cand. Prod. 1. p. 205 ; Schlecht. in Linn. 5. p. 213,

1. Cratseva Tapia. Linn. Herb. {nonSp. PI.) ; Velloz. Fl. Flum.b.t.3. — C. acuminata. 

 De Cand. Prod. sup. 243.— Cleorae arborea. Schrad. ; De Cand. I. c. p. 242.— Hab. 

 Acapulco. 



The stamens of our plant are considerably shorter than in Vellozo's figure referred to.
