Hab. Tavoy, Dr. Govan, Wallich. Mishniec, Ilclfcr. — Both the feitih; fronds 

 and young sterile ones have the remarkable sjiathulate form, as sliown in the 

 ' Icones Filienm.' This and the A. Shnonsianum are the most distinct, and, as 

 far as I can judge from all the specimens that have come under my notice, are 

 the most constant and uniform in character of the Thamnopteris group. 



7. A. (Thamnopteris) Shnonsianum, Hook.; small, fronds 

 Ih foot long 1 h inch broad cocspitose chartaceous elongato-lan- 

 ceolate abruptly and narrowly acuminate (rostrate) gradually 

 and very much attenuated below into a short stipes, veins 

 approximate suberecto-patent, sori copious rather distant, 

 three-fourthis the length of the veins and occupying three- 

 fourths of the superior portion of the frond. — Hook. Ic. Plant.

Hab. East Indies; Khasya and Unker \\\\\%, Simons. — ^Yhile suggesting the 

 diminishing the amount of species of other botanists of this Thamnopteris group 

 of Jsplenium, I may stand exposed to the charge of needlessly adding to their 

 number in the present instance. I can only say that with several fronds in my 

 possession, I have never seen this vary in its form or characters. It is a parti- 

 cularly neat and elegant species, very narrow-lanceolate, gradually decurrent below 

 into a very short stipes, and with the apices of their fronds all rostrate. 



B. EuASPLENiUM. Sori plane or nearly so', single (rarely double or diplazioid) . 

 Veins free, simple or branched, rarely in any way aras'iOniosvnr/. 



* Fronds undivided. 



8. A. (Euasplenium) serratum, L. ; caudex very short 

 erect, fronds cccspitose \\-2 or 3 feet long, elongato- or spa- 

 thulato-lanceolate acuminulate subcoriaceo-membranaceous 

 entire or generally more or less serrated or crenulate or 

 ineiso-dentate (towards the apex especially) below gradually 

 attenuated into a short winged stipes, veins linear and sori 

 rather distant varying in length tiie former clubbed at the 

 apex and terminating near the margin, stipes and rachis often 

 black acutely keeled at the back, in front slightly prominent 

 and depressed. — Linn. Sp. PI. p. 1538. Siv. Syn. Fil. p. 74.
