emarginate, petals. The length of the style is a variable character 
of the species. It may be a case of heterostylic condition. In 
fact, this assumption is strengthened by d’Apreval’s plate (Plant. 
Delavay., Plate xxiv.), which figures two forms of ovary in d 
and e: a long-styled and a short-styled one. Therefore, 
Franchet’s section Macrogyne is invalid, his A. Jdongistyla 
being, indeed, closely related to his A. napuligera. Our 
A. tonandra is an intermediate form between those two 
species. 
COMPOSITAE. 
\o*°" Pluchea Bulleyana, J. F. Jeffrey. Sp. nov. 
Planta biennis viscosa 30-80 cm. alta, basi ramosa, dense 
glanduloso-villosa. Folia caulina obovato-spathulata vel ob- 
lanceolata, apice mucronata, basi in caulem interrupte alatum 
late decurrentia, 5-8 cm. longa, 1-1°5 cm. lata, integerrima ; 
folia juvenilia basalia perlate ovata vel elliptica, circ. 7 cm. 
longa, circ. 5 cm. lata, in petiolum circ. 2 cm. longum subabrupte 
attenuata. Inflorescentia terminalis, folioso-corymbosa ; capi- 
tula plurima 7 mm. longa, 4 mm. diamet., heterogama disci- 
formia, alba ; flores exteriores multiseriati, styli ramulis patenti- 
bus filiformibus ; flores interiores, styli ramulis truncatis non 
patentibus, apice papillosis, antheris flavidis caudatis, connectivo 
apice producto. Pedunculi bracteati, molliter pubescentes. 
Involucri bracteae pauciseriatae, exteriores latae obtusae hyalinae 
pallido-brunneae, interiores angustiores, acutae. Achaenia minuta

“Plant of 31-24 ft. Flowers bright yellow. Dry, rocky 
situations on the descent from the Lu-po pass to the Salwin, 
Mekong-Salwin divide. Lat. about 27° N. Alt. 8~gooo ft. 
N.W. Yunnan. November 1905.” G. Forrest. No. 1073. Yun- 
nan-sen, E. E. Maire. Nos. 18, 707, 2288. 
A much-branched, viscid, leafy plant, densely clothed, especi- 
ally the stem and inflorescence, with villous hairs, the capitula 
almost cottony. Flowers bright yellow. The whole plant of 
a yellow hue, and aromatic when dry, suggestive of some species 
of Helichrysum. Mr. Forrest says :—‘‘ Strongly aromatic when 
fresh. Smell almost similar to that of curry powder.’’ Stem 
conspicuously winged by reason of the decurrent leaf bases, 
woody at base only with a fibrous tap root. 
A very distinct species, the nearest ally that I have seen 
being P.? pteropoda, Hemsl. Following Mr. Hemsley’s sug- 
gestion I place this in Pluchea,to which it is most nearly allied 
by the broad, blunt, subscarious involucral bracts, bifid styles of
