 latis acutis margine remotissime calloso-serrulatis in petioluru

In prov. Cantonensi, secus fl. North River, in. Jan. 1879 collegit 

 Dr. C. Geiiach. (Herb, propr. n. 20793). 



This interesting plant has so strong a resemblance to A. riigu- 

 losus, Maxim., and the sister species A. acuminatus, Miehx., that 

 any botanist would at first sight feel sure of their being immediate 

 allies. But both those species belong to a group of Orthomeris 

 which may be called alba (cfr. Torr. and Gray, Fl. N. Amer. ii. 

 160), in which the sockets of the receptacle are entire, the aehsenia 

 perfectly smooth, and the pappus-bristles clavellate. The present 

 plant falls into another group of the same section, acuminata, 

 which has the alveoli conspicuously toothed, the set^e of the pappus 

 filiform, and hairy achenes. Its nearest ally I take to be the some- 

 what variable A. tatariciis, Linn, f., from which it may be at once 

 distinguished by its habit, the peculiar colour of its far smoother 

 leaves, their very conspicuous attenuation into the stalk, the simpler 

 corymb, smoother and less herbaceous involucre-scales, the longer 

 narrower achene, and the non-rufescent pappus. I have compared 

 it with a considerable suite of allied species, and have no doubt of 

 its autonomy. 



81. Gnaphalium japemicum, Thunb. In collibus Feng-wang-shan, 

 prov. Kiang-su, d. 13 Maii 1877 coll. F. B. Forbes. I cannot 

 find any prior record of the existence of this species in China, 

 though its distribution would of course have led us to expect its 

 discovery in the country. 



32. Senecio aryunensis, Turcz. Ad ripas lacus Tung-ting, reg. 

 centr. prov. Hu-peh, aest. 1878 coll. Bullock. The most southerly 

 station known to me for this species. The capitula are smaller 

 than in any Peking or Manchurian specimens I have seen. 



33. Primula sinensis, Lindl. In umbrosis juxta I-chang, prov. 



Hu-peh, sub fine m. Jan. 1879 coll. am. T. Waiters, 



In this, the only wild specimen of this favourite plant I have 

 seen, the flowers are smaller and the leaves much less toothed 

 (resembling indeed rather those of /'. cortusoides, Linn.)» than in 

 cultivated ones.
