2, 372 (excl. syn. Carphephorus coridi/olius DC, which is clearly dis- 

 tinct). Mikania ericoides Mart, ex Bak. 1. c. (1876). 



Brickellia coridifolia (DC), comb. nov. Carphephorus coridi- 

 foUns DC. Prod. vii. 267 (1838). This species, resting solely upon 

 the original material collected on the Serro do Frio, Minas Geraes, 

 Brazil, in 1833, Vautier, no. 314, was placed by DeCandolle in the 

 genus Carphepho)-us doubtless because he found the receptacle chaffy 

 at least to some extent. Dissection of a head from a cotype in the 

 Gray Herbarium shows the receptacle to be chiefly free from chaff. 

 At only one point two narrow scales, like the inner ones of the invo- 

 lucre, were crowded in among the flowers, and formed, as it were, a sort of 

 re-entrant part of the involucre. In all other respects the plant agrees 

 technically with Brickellia. Mr. J. G. Baker, in treating the Eupatorieae 

 for the Flora Brasiliensis, doubtfully reduces the species to a synonym 

 of Brickellia pinifolia (Gardn.) Gray — a species above reduced to 

 B. brasiliensis (Spreng.) Robinson — but the plant, when compared 

 with B. brasiliensis is obviously distinct. The involucral scales for 

 instance are very different, being in C. cordifolius nearly twice as long 

 as in B. brasiliensis. They are furthermore much more attenuate, dis- 

 tinctly 3-ribbed, and dorsally glandular-puberulent, while in B. brasili- 

 ensis they are glabrous and minutely many-striate. In involucre the 

 plant agrees much better with Brickellia than with the North Amer- 

 ican genus Carphephorus. Moreover, the limb of the corolla is very 

 short as in Brickellia instead of being rather deeply cleft as in Carphe- 

 phorus. The afiinities of the species appear to be with B. brasiliensis, 

 though without doubt the plant is specifically distinct. The species 

 being little known it seems worth while to put on record the traits 

 brought out by recent examination. Capitulis 8-floris turbinato-cam- 

 panulatis 1.2 cm. altis ca. 1 cm. diametro ; involucri squamis lanceo- 

 latis vel anguste oblongis acutis dorso convexis tomentellis striatulis 

 ca. 3-seriatis valde inaequalibus ; receptaculo parvo piano cum paleis 

 paucissimis marginalibus irregulariter munito ; pappi setis ca. 30 

 barbellatis corollas aequantibus ; corollis 7-8 mm. longis vix sursum 

 ampliatis, dentibus limbi 5, 0.5 mm. longis ; styli ramis clavellatis ; 

 antheris anguste oblongis vix connatis apice breviter et late appen- 

 diculatis basi integris ; achaeniis immaturis 2 mm. longis papillo-

 intermediis. 



Brickellia diffusa (Vahl) Gray, PI. Wright, i. 86 (1852). Fupa- 

 torum dijusum Vahl, Symb. Bot. iii. 94 (1 794). To the synonymy of this 

 species should be added Eupatorium trichosanthum A. Rich. Fl. Cub. 

 Fanerog. ii. 41 (1853), the type of which was recently examined by
