34. (2.) Thlaspi Magellanicum, Pers. ?—Cerro del Porcura, 
Dr. Gillies.—Dr. Gillies’ specimens are in fruit only, 
so that the size of the petals is uncertain: they approach 
very closely to our last species. 
35. (1.) Cremolobus ? dinearifolius, (Hook. et Arn.) ; pusillus 
herbaceus, foliis linearibus integerrimis, racemis dense 
paniculato-corymbosis, siliculae lobis subglobosis rugosis 
immarginatis, stylo thecaphorum sequante.— Coquimbo, 
Cuming (N. 905.) — This curious little plant is not more 
than two incbes high, and yet appears to be an entire 
specimen, wanting, however, the root, which is probably 
annual; it is branched and panicled above, where the 
linear and somewhat fleshy leaves are -situated. It 
differs from Cremolobus by the turgid lobes of the silicule, 
_ which are quite destitute of margins, and ipay ae 
form the type of a new genus. -
