44 FLORA OF SOUTH AMERICA AND THE PACIFIC. 



Conyza trinervis, Lam. Baccharis trinervis, DC. — Ura- 



guay. Tweedie. — This differs from the generic character only 

 in the female florets not being ligulate. In all other respects 

 it approaches B. psidioides. Less. It is surely Baccharis 

 trinerviSf Pers. and De Cand. 



Subtrib. III. TARCHONANTHEiE. Less. 

 MicRopsis. DC. 

 (Lasiophyton. Hook, et Am. mst.) 

 Involucrum scariosum subbiseriale. Capitulum heteroga- 

 mum pauci-(sub-9-)-florum ; flosculis foemineis uniseriaHbus 

 filiformibus in ambitu : Jl. hermaphroditis tribus tubulosis in 

 centre intra rachidis uniseriales isaritlimas dispositis. Anthe- 

 rcE basi bisetosae. Stylus herm. rami pube infra apicem de- 

 currente obsessi. Achania estipitata erostria oblonga ; /hem- 

 sericeo-villosa, villis pappum occultantibus ; herm, glabra 

 compressiuscula, hinc linea sericea notata, bracteolis membra- 

 naceis valde concavis apice scarioso-appendiculatis dorso gib-

 ata, terminnlia, foliis sub capitidis involucrata. Hook, et Am. 



1107. (1.) M. nana {DC. Prodr. v. p. 460.) Lasiophyton 

 pusillum. Hook, et Am. 7nst. — Cliili. Valdivia. Bridges (n. 

 642). Quillota. Bertero. — We have placed this genus here 

 in deference to the opinion of De CandoUe, although our 

 observations on the style of the central florets, which that 

 eminent botanist has described as male, lead us rather to 

 insert it among the GnaphaliecB, near Gifola. 



1108. (I.) If^licropus globiferus {Bert, in De Cand, Prodr. v. 

 />. 460); totus niveo-tomentosus, caulibusa basi ramosis diffu- 

 sis, foiiis oblongo-iinearibus, floralibus latioribus obtusis, capi- 

 tulis terminalibus lateralibusque invol. squamis planiusculis 

 inermibus tomentosis obtusissimis.— Cliili, at Kancagua. — 

 Bertero, Wc are unacquainted with this.
