PLUCHEA Cass. 
Pluchea rubicunda C. Schneider, n. sp. 
Frutex ut videtur erectus et laxe ramosus, 1.5-5 m. altus; ramuli 
floriferi teretes, dense cano-tomentelli pubescentes, partim glandulosi. 
Folia alterna, membranacea, elliptica v. elliptico-lanceolata v. sub- 
ovato-elliptica, basi acuta, vix in petiolum decurrentia, apice plus 
minusve breviter acuminata acumine interdum satis subito producto, 
margine indistincte et distanter subrepando-brevidenticulata v. fere 
integra, supra viridia, omnino (in nervis densius) brevissime glanduloso- 
puberula, subtus canescentia, satis dense ut ramuli tomentella, nervis 
lateralibus utrinsecus circiter 7-8, etiam reticulo paulo prominulo, ma- 
jora ad 16 cm. longa et paulo infra medium ad 7 cm. lata, minora basi 
inflorescentiae 5-12 cm. longa, 2-4 cm. lata; petioli cano-tomentelli, 
8-11 mm. longi. Inflorescentiae paniculato-corymbosae, circiter 6 
em. altae et ad 20 cm. latae, ut ramuli cano-tomentellae; capitula 
numerosa, discoidea, ut videtur homogama, 5-7 mm. erassa; involucri 
bracteae pluriseriatae, adpressae, subscariosae, exteriores ovato- 
ellipticae, interiores elongatae, omnes obtusae, in dorso sericeo-tomen- 
tellae; receptacula plana, nuda. Flores visi omnes hermaphroditi, 
numerosi, circiter 10-12 mm. longi, rubieundi; pappi setae albae, 
biseriatae, exteriores interioribus 3-4-plo breviores, achaenio vix 
aequilongae, interiores eorollam subaequantes; corolla extus pilis glan- 
dulosis paucis obsita, lobis lanceolatis tubo 3-plo brevioribus; antherae 
basi caudatae; stylus pro genere normalis, apice bifidus et pilosus; 
achaenia immatura tetragona, sparse pilosa. 
Western Szech'uan: Kiating Fu, thickets, alt. 100-800 m., Sep- 
tember 1908 (No. 3403; bush 1.50-5 m. tall, flowers pink). 
Judging by the bracts of the involucre, the style and the anthers this plant 
belongs to the genus Pluchea as fixed by Hoffmann in Engler & Prantl, Nat. 
Pflanzenfam. IV. 5. Abt. 176 (1890), but, so far as I know, all the species hitherto 
described have a l-serrate pappus. It looks different from all the species of this 
genus or of Blumea known from Asia. Further observations are needed to determine 
E plant belongs to Pluchea, but I know of no other genus to which it could be 
erred.
