38. ASPLENIUM, KUASPLENIUM. 191 



3. p. 78. y, A. Australasicuin, Hk. ; midrib keeled on the back, often black. 

 We. F. Ex. t. 88. 



Hab. Mauritius, Johanna Island, Seychelles, Himalayas, Japan, Bonin, and Chusan, 

 westward to the Society Islands ; southward to New Caledonia, Queensland, Norfolk 

 Island, and Lord Howe's Island. The Himalayan and Malayan A. Phyllitidis, Don, 

 seems to differ from the type only by its smaller size. The aori in some of the specimens 

 are quite as close as in any of the above. A. pachyphyllum and tceniosum, Kunze, we 

 have not seen. A plant from Malacca and Java has the veins in. apart and much 

 broader sori. 



2. A. (Thamn.) Grevillei, Wall. ; fr. 12-18 in. 1., 2-3 in. br., lanceolate- 

 spathulate, narrowed to an acute apex and suddenly below to a broad wing to 

 the stipe, which grows very gradually narrower downwards, the margin entire ; 

 texture coriaceous ; midrib keeled below ; veins nearly horizontal, those in the 

 body of the fr. about \ lin. apart ; sori on most of them extending within a short 

 distance of the edge. Hk. Sp. 3. p. 80. Hk. & Gr. Ic. t. 128. 



Hab. Gathered in Tavoy by Dr. Wallich and Mishmee by Heifer. 



3. A. (Thamn.) Simonsianum, Hk. ; fr. 12-18 in. 1., 1-1| in. br., tapering 

 above into an acuminated point and very gradually below into a short stem, the 

 margin nearly entire ; midrib only rounded and prominent below ; texture 

 coriaceous ; veins erecto-patent, about | lin. apart ; sori copious, reaching from 

 the midrib to within a short distance of the edge. Hk. Sp. 3. p. 81. Ic. PL 

 t. 925. 



Hab. Khasia and linker Hills, Bengal, Simons, 232. This and the preceding are two 

 little-known plants, perhaps not really distinct from No. 1. 



Euasplenium. Veins free, simple or branched; sori linear or linear-oblong, 

 straight, discoidal. Sp. 4-154. Fig. 38. a. 



/ 

 * Fronds quite entire. Sp. 4-17. Phyttitis. J. Sm. 



4. A. ensiforme, Wall. ; st. tufted, 1-3 in. 1., firm, erect, scaly below ; fr. 

 12-18 in. 1., ^-| in. br., much acuminated towards the point, edge nearly entire, 

 lower part narrowed into the stem very gradually ; texture coriaceous ; veins 

 immersed, inconspicuous, erecto-patent, usually once forked ; sori broad, reaching 

 nearly to both midrib and margin. Hk. Sp. 3. p. 90. Hk. & Gr. Ic. t. 71. 



Hab. Himalayas (ascending to 10,000 ft.) to Ceylon; Moulmein. The Mexican 

 A. coriaceum, ~F6e, seems from the description to agree with this. 



5. A. angustum, Swartz ; st. tufted, short, firm, greyish, erect ; fr. 1-2 ft. ]., 

 1-1^ in. br., linear-lanceolate, the point much acuminated, the margin nearly 

 entire, or the point a little serrated, the lower part narrowed very gradually to 

 the stem from two-thirds of the way down ; texture subcoriaceous ; veins erecto- 

 patent, usually simple ; sori rather distant, reaching from the midrib nearly to 

 the edge. Hk. Sp. 3. p. 89. A. loriforine, Hk. Ic. 926. 



Hab. Brazil and Guiana. 



6. A. concolor, Hk. ; st. tufted, 1-2 in. 1., firm, greenish, clothed with scales in 

 the lower part ; fr. 6-8 in. 1., 1 in. or more br., lanceolate, the point acute, the 

 edge slightly crenato-serrate upwards, the lower part narrowed into the stem 

 very gradually ; texture herbaceous ; veins usually simple ; sori numerous, 

 narrow, extending from the midrib to the edge. Hk. Sp. 3. p. 88. t. 164. A. 



Hab. Java ; and a very similar plant, but with a longer stem and frond, has been 

 gathered on the Guinea coast by Messrs. Curror, Barter, and Mann.
