296 SPICILEGIA FLOR.E SINENSIS. 



pinnae, aii inch to half an mch apart, or with a similar outline. 

 The Chinese plant, though having the under surface of the frond 

 white, most nearly resembles tab. 95, fig. 1 of Sn William Hooker's 

 ' Filices exoticae,' given as C. argentea, var. chnjsoj^hyUa, which I 

 regard, with Messrs. Clarke, Atkinson, and Henderson (Trans. 

 Linn. Soc. ser. 2, i. 458), as certainly more nearly allied to 

 C. farinosa than to C. arfjentea, all the Chinese specimens of which 

 latter are very similar. A Khasia plant given me by Prof. Eeich- 

 enbach as C. chnjsophi/Ua is exactly hke fig. 2 left-hand specimen, 

 of the plant above referred to, and is, I suppose, a form of C. 

 argentea. The late Dr. Milde seems to have considered both of the 

 above forms as referable to C. farinosa (Fil. Europ. &c. 38). Since 

 the above was written, Mr. Henry has given me thoroughly typical 

 specimens of C.faiinosa from Fei-loi-tsz. 



74. Asjjleyiium ccenobiale, Hance. — Secus fl. North River, prov. 

 Cantonensis, m. Jan. 1879, leg. Dr. C. Gerlach. These are the 

 specimens on which Mr. Baker founded his A. fuscijies; which, 

 however, proves on comparison in all respects identical with my 

 fern from the West River, described five years previously. 



75. Aspidium ohliquum, Don. — Secus fl. Lieu-chau, prov. Can- 

 tonensis, m. Martio 1881, detexit rev. B. 0. Henry. The only 

 Chinese specimens I have seen. 



76. A. intermedium, Bl. — In prov. Cantonensis, secus fl. Lien- 

 chau, Martio 1881, coll. rev. B. C. Henry. Very fine specimens 

 indeed; the first I have examined h'om any part of China. 



77. Cyathea spimdosa. Wall. — In declivibus occasum spectanti- 

 bus jugi Lo-fau-shan, h. e. "montes tigridum,'' prov. Cantonensis, 

 alt. 20 pedum adtingentem, m. Novembri 1880, primus detexit 

 Dr. C. Gerlach. Only found hitherto in Nipal and the Jaintea 

 hills, and in the island of Usima, South Japan ; if, indeed, the 

 plant from the latter locality be correctly determined. The Chinese 

 specimens appear really referable to this species, as recently dis- 

 cussed in a very masterly paper on the Ferns of Northern India, 

 by Mr. C. B. Clarke (Trans. Linn. Soc„ 2nd ser. i. 429, t. 49, f. 1). 



78. Physcomitrium eunjstomum, Sendtn. — In muris, Whampoae, 

 primum legit carissima uxor, m. Martio 1880. Determination by 

 M. Bescherelle, confirmed by Dr. Braithwaite. 



79. Arthrocardia conjmhosa, Aresch. — In rupibus maritimis ad 

 Ki-lung, 01-33 borealis ins. Formosse, exeunte Januario 1882, leg. 

 T. Watters. I fail to see any difference between this and a New 

 Zealand specimen received from the late Prof. Harvey, except that 

 his belongs to Agardh's var. a, and this to /3. Its occurrence in 

 Formosa, exactly 25° north of the equator, is remarkable, as the 

 usual South African locality is in about 32° south latitude ; and 

 J. G. Agardh states (Spec. Alg. ii. 2, 549) that no species of 

 Arthrocardia, except the little known A. frondescens, J. G. Ag., 

 which is perhaps not congeneric, has hitherto been found in the 

 northern hemisphere.
