SPICILEGIA FLORAE SINENSIS. 109 



possession, wliicli bear each a single flower, to ascertain the structure 

 of the florets and achenes of this pretty plant, but I suspect it may 

 be most nearly allied to the very rare and local Pyrethrum Kiriloirii, 

 Turcz., on which Schultz Bipontinus, following a suggestion of 

 DeCandolle, founded his genus Tridactijlina. DeCandolle describes 

 that plant as havmg "habitus C. Mijconis; folia multo majora quam 

 ISaxifragce tridactj/litis, sed forma affinia ;" and F. v. Herder (' Plant. 

 Eadd.,' bd. 3, hft. 2, 40) remarks on its resemblance to C. arcticum, 

 Linn. The leaves of Turczaninow's species are moreover described 

 as obovate-cuneate, its ligulae as yellow, and there is no mention 

 of the very hairy involucre -scales, so it seems impossible to refer 

 Mr. Hancock's plant to it. It is quite different from any Siberian 

 species known to me. 



27. Artemisia [Ahrotanum) vestita, Wall. Supra pagum Tai-wan, 

 secus fl. Lien-chau, j)rov. Cantonensis, Oct. 1876, leg. Eev. J. C. 

 Nevin. Previously gathered in Shan-tung by the late Dr. Maingay, 

 and at Kiukiang by Dr. Shearer ; otherwise new to China. 



28. Saussurea alpina, DC, var. leucophylla, Led. ? Li m. Siao 

 Wu-tai-shan, Chinas bor., Jidio 1876, coll. Hancock. I think 

 referable to this form, but I have seen no authentic specimens. 



V 29. Saussurea (bracteatce*) iodostegia, sp. nov. Caule simplici 

 inferne glabro apicem versus laxe villosulo, foliis iuferioribus ? 

 mediis linearibus acutis margine denticulis x^arvis j)atentibus 

 notatis sparsim pilosulis basi vaginantibus ac breviter decurren- 

 tibus 2|— 5 poll, longis 3 lin. latis superioribus ovato-lanceolatis 

 summisque ellipticis cucuUatis submembranaceis bracteiformibus 

 integris plus minus violaceo-tinctis venisque purpurascentibus reti- 

 culatis, capitulis 4 pedunculis brevibus villosis suffultis ovato- 

 oblongis 7 lin. longis, squamis laxe glanduloso-pilosis exterioribus 

 ovatis interioribus ovato-lanceolatis obtusiusculis medio purpureo- 

 pictis margine atro-i)urpureo cinctis. In m. Siao Wu-tai-shan, 

 Chinae septenlrrionahs, m. Julio 1876, legit W. Hancock. (Herb, 

 propr. n. 20148.) 3< 



I have only a single imperfect specimen, but the plant is 

 evidently a near ally of the Himalayan *S'. ohvallata, Wall. 



30. Lobelia radicans, Tlibg. Ad^ipas limosas fluviorum North 

 et West Kivers, prov. Cantonensis, copiose. Quite identical with 

 Japanese specimens. Though not before recorded from China, I 

 have no doubt, judging from the characters assigned them, that 

 several of A. DeCandolle's species are reducible to this. 



31. Rhododendron (Azalea) sinense, Sweet. In insula Tung-dung- 

 ding-san, lacus Tai-hu, prov. Che-kiang, exeunte Aprih 1874, 

 coll. T. B. Forbes. Excellent specimens of a plant very rare in a 

 wild state. 



32. Pijrola (Thelaia) rotundifolia , Lindl. In m. Siao Wu-tai- 

 shan, Chinae bor., Jul. 1876, coll. W. Hancock. Both the forms, 

 alhijiora and incarnata, which are surely not deserving of the rank 

 of varieties.
