Hab. Conception. — This does not differ from the larger state of C. hirsuta found in our country, and 

 which Continental Botanists have called C. sylvatica: and it equally appears to be the C. flaccida of 

 Chamisso and Schlechtendal, which the former Naturalist gathered also in Chili. 



2. C. tenuirostris ; foliis pinnatis, foliolis omnibus anguste linearibus acutis integerri- 

 mis, petalis obovatis unguiculatis calyce duplo longioribus, siliquis erectis gracilibus in 

 rostrum tenuissimum attenuatis. 



Caules erecti, flexuosi, glabriusculi, striati, suhpedales. Folia omnia pinnata, glabra vel, sub lente, pilis 

 minutis hirsuta ; foliolis omnibus anguste linearibus, acutis, integerrimis, foliorum superiorum angustissimis. 

 Flores corymbosi, majusculi. Pedicelli graciles. Sepala oblonga, erecta, glaberrima. Pctala alba, oblongo- 

 obovata, in unguem attenuata, sepalis duplo longiora. Siliquce, vix maturse, unciam lougte, erecta?, graciles, 

 basi in stipitem brevem, apice in stylum vel rostrum semiunciam longum, tenuissimum attenuata?. Stigma 

 parvum, capitatum. 



Hab. Conception. — In habit this plant is certainly allied to C. pratensis, and especially to that var. 

 with narrow leaflets which is described in the Flora Boreali- Americana, under the var. angustifolia : but 

 its leaflets, and in particular those of the root-leaves, are still narrower, the flowers are smaller, and, in 

 the extremely attenuated beak to the pods, it differs from all the species we are acquainted with.

1. L. bipinnatijidum ; siliculis ovalibus emarginatis, foliis pinnatipartitis,. rachi alata, 

 lobis multifidis, ramis pubescentibus. DC. — Desv. Journ. Bot. 1814. p. 165 et 177. De

Hab. Valparaiso. — The specimens in the collection are extremely small, scarcely two inches high, erect 

 and simple. Those we have from the same country, gathered by Mr. Bridges, are a foot long, much 

 branched, especially from the base. In both we find all the essential characters of the L. bipinnatijidum 

 of Desvaux, who justly observes that it is nearly allied to L. bonariense.
