14 SPICILEGIA FLOR.E SINENSIS. 



described species, agreeing rather with the Madagascar ^crocep/ia^Ms 

 villosus, Benth., and appears to point to the propriety of combining 

 the two genera. Technically, hideed, it is rather an Acrocephalus, 

 but it is certainly less close to A. capitatus, Benth. ! — the only 

 Asiatic species — than to G. elongatum, Benth. ! which is apparently 

 its nearest ally, and which it is a good deal like both in foliage and 

 inflorescence.

 Cantonis, Oct., 1869, detexit Sampson. 



46. Amarantus retwflexus, Linn. Prope Ta-chiao-sze, ditionis 

 Pekinensis, m. Sept., 1874, leg. Dr. 0. a Moellendorff. This widely- 

 spread weed, suspected by Dr. Cosson to be of American origin 

 ('Ann. sc. nat.' 3e. ser vii., 212), has been found in various parts of 

 Siberia ; but the present is, I believe, the first indication of its 

 occuiTence anywhere in China. 



47. Aenia scandens, Moq., var. minor. In bambusetis prope 

 pagum Sai-nam, secus fl. North Eiver, prov. Cantonensis, d. 15 

 Sept., 1866, coll. Sampson et Hance. The Chinese plant is 

 certainly referable to this species, in Dr. Thwaites's judgment, but 

 it looks very unlike the Panjab and Sikkim specimens distributed 

 by Hooker and Thomson. 



48. Polygonum Do7iii^ Meissn, Accepi a variis imperii chinensis 

 regionibus, ipseque in provinciis Fokienensi atque Cantonensi legi. 

 Mr. Bentham considered the Chinese plant as a variety of P. 

 barbatiun, Jjmn.,hi\t it is much slenderer, agrees perfectly with 

 Meissner's diagnosis, and is more like P. Posnmbu, Ham. From 

 Peking and the North Eiver I have specimens with the leaves 

 glabrous beneath, but with conspicuous raised granular dots, and 

 the primaiy veins less distinct. 



49. Polygonum serridatum, Lag. Ad ripas fl. Cantonensis, m. 

 Sept., 1866, legg. Sami)son et Hance. Though very widely distri- 

 buted, not, I beheve, before recorded from China. 



50. Aporosalanceolata, Thv7. In silva supra monasterium Ting- 

 ii-shan, secus fl. West Eiver, d. 10 Julii, 1870, leg. Sampson. Not 

 before reported from China. 



51. Bctida alba, Linn., subsp. latifolid v. Taiischii, Egl. In 

 monte Po-hua-shan, Chinse bor., d. 6 Oct., 1874, coll. cl. Dr. 0. a 

 Moellendorff. 



62. Bctula davurica, Pall. Cum priore. 



58. Betula Krmani, Cham. Cum prEecedentibus. M. Maxi- 

 mowicz, in his 'Index flor^B Pekinensis,' mentions but one species 

 of Birch, which he refers doubtfully to B. davurica. I have before 

 had occasion (Trimen's ' Journ. Bot.' xiii., 137) to speak of three 

 species found on Po-hua-shan by Dr. Bretschneider. The speci- 

 mens now forwarded from the same locality by Dr. 0. .von 

 Moellendorff are far from satisfactory, being too much advanced, 

 the catkin-scales and nucules very deciduous, and the second only 

 having any leaves. Nevertheless, a careful comparison with 

 authentic specimens in my herbarium makes me feel quite confident 

 as to the accurate determination of the second and third, and 

 tolerably certain also with regard to the first. Dr. von Moellendorff
