attenuatis subtus hirtis, pedicellis ovario brevioribus ebracteolatis, calycibus lobis 4 ovatis 

 acutis basi 5-7-nerviis, tubo obconico subcylindraceo-ovato 4-nervio, petalis obovatis 

 calyce longioribus. De Cand. Prodr. 3. p. 57. Hook, et Arn. supra, p. 291. 



Hab. San Bias to Tepic. — We possess the same plant from various parts of S. America, but are by no 

 means certain of our correctness in referring it to the J. hirta of Vahl. The leaves vary much in different 

 specimens, from ovato-lanceolate to oblong-lanceolate, the hairiness is chiefly confined to the upper part of 

 the plant. The pods are about an inch and a half long, when ripe, destitute of the calyx-segments.

Hab. 0. Between San Bias and Tepic. — Dr Sinclair's specimens differ in no respect from those gathered 

 during Captain Beechey's former voyage, except in being more pubescent, especially in the younger parts of 

 the plant, and upon the flowers, and in there being rather longish spreading hairs mixed with the down upon 

 the calyx and pedicels.

1. Lopezia hirsuta; caule elato suffrutescente reflexo-piloso, ramis elongatis strictis 

 gracilibus, foliis oppositis ovatis seu ovato-lanceolatis petiolatis obscure serratis hirsutis, 

 racemis terminalibus superne paniculatis. Jacq. Coll. Bot. p. 5. t. 15. f. 4. De Cand. 

 Prodr. 3. p. 62. Hook, et Arn. supra, p. 291. 



Hab. Between San Bias and Tepic. — A very graceful plant. The leaves gradually pass upwards among 

 the branches into small bracteas. The hairs with which almost every part of the plant is clothed, except the 

 pedicels and flowers, are rather long and seated upon a small bulb ; those of the stem and petioles and midrib 

 beneath are more harsh and rigid than the rest, reflexed and very close pressed. Pedicels extremely slender, 

 subtended by a minute bractea. — The figure of Jacquin above quoted is an excellent representation of a 

 flowering branch.

Hab. San Bias and Tepic. — We had considered this to be a new species: but Mr Bentham has referred 

 specimens of the same plant in Hartweg's Mexican collections (n. 25) to the C. Llavea, of La Llave and De 

 Candolle, which latter author has thus characterized it: " caulibus pluribus hispidulis, ramis ascendentibus, 

 foliis subsessilibus ovato-lanceolatis strigosis, pedicellis interfoliaceis erectis, petalis 2 obovatis magnis, cseteris 

 abortivis, stam. 1 1 ." — Our character will be seen (supra, p. 289.) — Our specimens in the present collection are 

 a foot and a half to two feet long, extremely rough with the copious rigid hairs or bristles, with which every
