2. B. mollis (Don) Merrill comb. nov. 
Erigeron molle Don Prodr. (1825) 172. 
Conyza bifoliata Chamisso & Less. in Linnaea 6 (1831) 135. 
Blumea chamissoniana DC, Prodr. 5 (1836) 454. 
Blumea wightiana Hook. f. Fl. Brit. Ind. 3 (1881) 261, non DC. 
In stream depressions, pine region, altitude 1,300 m, 0. M. Z. 16334. 
Widely distributed in the Philippines at low and medium altitudes; India to 
southern China, Malaya, Australia, and tropical Africa. 
What is apparently the oldest specific name is here adopted, but in accepting 
this name I have followed the authority of Hooker f., who made the reduction. 
According to Hooker f. Blumea trichophora DC., B. parvifolia DC., and B. phyl- 
lostachya DC., the former based at least in part, on Hrigeron molle Don, the 
other two on nomina nuda of Wallich’s “Catalogue,” sub Conyza, as well as 
Blumea leschenaultiana DC., are all synonyms of Blumea wightiana. I have 
examined the type of Blumea chamissoniana DC. in the Berlin Herbarium, as 
well as the duplicate in the DeCandolle Herbarium, and also the type of B. 
wightiana DC, in the latter institution. The specimen on which Blumea wight- 
iana DC. was based does not appear to me to specifically identical with the 
specimens so named in the Kew Herbarium, on which the English botanists have 
based their conception of Blumea wightiana. Prain”™ in discussing the Wallichian 
Herbarium, as distributed, in connection with the early volumes of the ‘“Pro- 
dromus” warns all botanists, who wish their results to be accurate, to place no 
confidence in the Wallichian name for a species in any of the families treated by 
DeCandolle before the Wallichian Herbarium was issued, without first confirm- 
ing it by comparison with the specimen so named in the “Prodromus” Herbarium, 
as Doctor Wallich placed no numbers on the sheets he originally sent to De- 
Candolle, and many of the identifications of DeCandolle’s species were manifestly 
made by Dr. Wallich without referring to either DeCandolle’s descriptions or 
specimens. 
3. B. incisa (Elmer) Merrill comb. nov. 
Pluchea incisa Elmer Leafl. Philip. Bot. 1 (1908) 358. 
Herba erecta vel subscandens; foliis usque ad 8 cm longis, 2.5 cm 
latis, subsessilibus, superioribus sensim minoribus, subcoriaceis vel char- 
taceis, scabridis, leviter pubescentibus, acuminatis, irregulariter lobatis 
vel incisis; capitulis circiter 1 cm longis, breviter pedicellatis vel sub- 
sessilibus, squamis imbricatis, pubescentibus. 
Upper pine region, altitude about 2,000 m, C. M. Z. 16123. 
This species was described by Mr. Elmer as a Pluchea, based on a specimen 
collected by himself in Benguet, no. 8396. It appears to me to be a Blumea, and 
closely allied to B. chinensis (Linn.) DC., rather than a Pluchea, and is accord- 
ingly here transferred to the former genus. Mr. Elmer considers it to be allied 
to Pluchea scabrida DC., but the material identified by him as Pluchea scabrida, 
I consider to be referable to Blumea, a species very closely allied to if not identical 
with Blumea chinensis (L.) DC. Pluchea scabrida DC., the type of which I have 
examined in the DeCandolle Herbarium, is apparently only a very pubescent form 
of Pluchea indica (Linn.) Less., although placed by DeCandolle in the section 
Hebephora. : 
Known only from high altitudes in Benguet.
