the Involucre in the male and female capitula. The name is 

 a very bad one, and only tends to mislead.

Uraguay. Tiveedie {ri. 1000) A small mucli branching 



glabrous shrub, with leaves like those of Myrsine retusa, glossy 

 and opposite, and capitula as in B. concava, clustered, 

 scarcely pedicellate, at the extremity of the branches. 



1074. (31.) B. Macraei (Hook, et Arn.); fruticosa ramo- 

 sissima, ramis teretibus dense pubescenti-tomentosis, foliis 

 sessilibus obovato-cuneatis coriaceis uninerviis superne 3-

 pappo duplo brevioribus — Valparaiso. Macrae. — Leaves 

 much resembling those of B. coticava, but the branches are 

 stunted, terete, densely downy tomentose, the capitula soli- 

 tary, terminal, thrice as large as in the preceding species; 

 the pappus much longer and more silky. 



1075. (32). B. rotundifolia (Spreng. ?) fruticosa, ramis 

 teretibus, ramulis striato-angulatis subviscosis, foliis sessilibus

 Brazil, Fort Argentino, N.Patagonia. Tweedie. Monte Video. 

 [ex. Herb. Baldivin. Dr Torrey). — If we are right in refer- 

 ring these several plants to B. rotundifolia, as we think we are, 

 it is a most variable species. From Rio Grande {Tweedie) we 

 have three specimens; in all the three, the nerves are distinct
