 — a. foliis involucrique squamis integerrimis. — ,5. foliis serratis 

 involucri squamis margine erosis. — a. Buenos Ayres {Herh. 

 Baldwin). Boggy places, Bahia Blanca, N. Patagonia. Tu'eedie 

 (ji. 400). Wet spots, near the mouth of Rio de Uspallata, 

 Andes of Mendoza. Dr Gillies (n. 190). — ,8. S. Patagonia, 

 Lat. 47°. C. Darivin, Esq — Evidently an annual plant, vary- 

 ing in height from six inches to two feet, the stems and 

 branches singularly rounded and even, thickish and j unci- 

 form, spongy within. Leaves always remote, one to nearly 

 two inches long, erect and frequently appressed, slightly 

 fleshy, generally with no appearance of costa or nerve. Capi- 

 tula large. It is the same species detected by Dr Gillies in the 

 Andes of Mendoza which Mr Tweedie finds upon the coast 

 of Patagonia. It is readily distinguished by the nature of its 

 stem and leaves, and the beautiful coloured (purple) acumi- 

 nated scales of the involucre with frequently white silvery 

 margins. Pappus an inch long, tawny.* 



1092.(49). B. Darwinii (Hook, et Arn.) ; suffruticosa erecta 

 puberula, ramis angulato-striatis, foliis remotis Hnearibus 

 canaliculatis subcarnosis obscure uninerviis integerrimis pilo 

 vel mucrone molli terminatis, capitulis solitariis terminalibus 

 in ramulos ultimos subcorymbosos, involucri hemisphasrici 

 squamis obsolete uninerviis lanceolatis acuminatis marginibus 

 late scariosis integerrimis. — Port Desire, lat. 47°. C. Dancin, 

 Esq. {n. 397.) — Our specimens are small, and do not exhibit 

 the lower part of the plant, but they suffice to show that the 

 species is very distinct from any other. Leaves an inch long. 



* May this not be the Stephananthus junceus, Lehm. {Bacc/iaris juncea, 

 DC. 1. c. p. 423), which Lessing says is a native of South Brazil, and not 

 of " Egypt ;" the character agrees tolerably well.
