. SPICILEGIA FLORAE SINENSIS. 329 



61. Potamof/etoiiis sp. — Ad 11. Lieu-cliau, prov. Caiitonensis, m. 

 Oct. 1882, coil. rev. li. H. Graves. A solitary fragment of a 

 distinct-looking plant, with opposite, very crispate leaves (the 

 lamina 3 in. and petiole f in. in length) terminated by a con- 

 spicuous rigid apiculus, 1 line long, a thick peduncle with a dense 

 spike of flowers about an inch long, and a single fruit, bright 

 brown in colour, obliquely ovoid, faintly ribbed, and with a very 

 short beak. I have little doubt that this is identical with the plant 

 referred to by Maximowicz (Fragm. ad fl. As. or. cognit. mel. 59) 

 as found at Peking, in the Philippines, and the Malay Archipelago. 



52. C'l/perus {MariscKs) dilutus Vahl.- — Ad radices montium Pak- 

 wan, supra Cantouem, vere 1884, leg. T. Sampson. Very fine speci- 

 mens of this showy species, of which I have seen none from any 

 other locality in China. 



63. Carex pedifonms C. A. M. — In collibus prope Hu-chau, 

 prov. Che-kiang, d. 15 Apr. 1881, coll. Carles et Forbes. I had 

 not, before the receipt of this specimen, seen Chinese ones from 

 any locality south of the Peking mountains. 



54. Pteris qiiadriaurita Eetz. var. — Juxta pagum Ta-men-tiu, in 

 territorio indigenarum Lai, ins. Hai-nan, d. 24 Oct. 1882, leg. rev. 

 B. C. Henry. This agrees quite well with Agardh's brief diagnosis 

 of P. Grevilleana Wall. (Eev. sp. gen. Pter. 23), and equally so 

 with Mr. Baker's note on a Borneo fern collected by Mr. Burbidge, 

 and named by him as var. digitata (Journ. Bot. 1879, 40), but I 

 have seen neither. Though very different in habit from well- 

 developed specimens of 7-". qucidriaurita, it is, I have little doubt, 

 referable to that species. The costal spinules are very con- 

 spicuous. 



65. AspJeninm rescctmn Sm. — In monte olim ignivomo, nunc 

 exstincto, Ta-tun, jurisdictionis Tam-sui, ins. Formosfe, d. 15 Jun. 

 1882, leg. W. Hancock. This shows such an evident approach to 

 A. heterocarpum Walk by the greater pellucidness of the leaflets, 

 their narrow more acuminate shape, and the tendency of the sori 

 to be marginal, that I am disposed to think the latter fern may 

 prove to be an extreme form of this widely diffused species. 



56. Aspidiimi paludoHum Bl. (Fhei/upteris distcins Mett.). — Ad 

 limites territorii indigenarum ins. Formosre, 28 m. p. a Tam-sui, 

 austrum versus, in fruticetis dcnsis, d. 12 Feb. 1882, rarissimum 

 invenit cl. W. Hancock. Only hitherto known from the Indian 

 mountains, Ceylon, and Java. The specimens agree perfectly with 

 a Ceylon one from Dr. Bradford. 



67. Polijijodiuni innanimii Wall. — In jugo Lo-fau-shan, prov. 

 Cantonensis, m. Maio 1883, coll. rev. B. C. Henry. A native of 

 the loftier Indian mountains, and found in Formosa, but not before, 

 so far as I am aware, in south continental China. 



68. Pobjpodmm Lehnamii Mett. — In jugo Lo-fau-shan, alt. 

 2-3000 ped., Maio 1883, satis copiose invenit rev. B. C. Henry. I 

 have seen no authentic specimens, but have determined it from 

 Mettenius' and Baker's diagnoses. It bears small trifid sterile 

 fronds, unlike the fertile ones. Only hitherto known from the 

 Himalaya and Burma.
