down, ■with otlong, blunt, crcnate lobes ; sori few, marginal in the crcnations." 

 — Uuohr. On limestone rocks in the neighbourhood of Maulmain. In cre\'iccs about 

 the mouth of the Damatliat Caves ; but very difficult to extract owing to the depth 

 at which the rhizomes hide themselves, and the brittle nature of the stipites. Only 

 to be found during, or immediately after, the rains. 



LiNDSAYA,' Bryander. 



This genus is distinguished by having its sori in a continuous line close to the 

 margin of the frond, covered by a continuous indusiuni, which opens outwards. 



L. lANTJGINOSA. 



L. lanuginosa is a rare plant. It has a creeping rhizome clothed with small scales. 

 The fronds arc veiy long and narrow ; the stipes 5 or 6 inches, the frondose portion 

 two feet long by some 4 inches broad, simply pinnate ; pinmc 2 inches long by A an 

 inch, and bluntly rounded at the end in the bari'cn frond ; narrower in the fertile 

 frond. The pinua^, being jointed on to the rachis, fall off in drying, wliich makes 

 the dried specimens wear a wretched appearance. It very much resembles Xephro- 

 lepis acuta in appearance, and, like it, has little chalky dots along the edge of the 

 upper surface of the pinnte. 



Found by me on one Palmyra tree only in Tavoy, and gathered only once, 

 owing to the circumstance that the fronds disappear soon after the rains are over, and 

 my visits to Tavoy were, on all but one occasion, made in the dry weather. No 

 doubt a resident would find it on other trees. 



L. EXSIFOLIA, Sw. 



L. Griffithiana, Hook. 



A most variable plant. In its " ensifolia " form, it is found on the hill over- 

 looking Maulmain. This form shall be first described. Fronds closely set upon a 

 slightly creeping rhizome, roots numerous, wiry. Height varying fi'om 8 inches to 

 18, or even more; stipes about half the height; frondose portion pinnate ; ])innie 

 opposite or nearly so, 5 or 6 paii's and a terminal one, on short stalks, narrow, 

 linear, blunt-poiuted, the lowest the longest, 5 or 6 inches long by ^ inch broad, 

 sliortt'ning upwards, the topmost sometimes pinnatifid. The stipes is slender, smooth 

 and light brown in colour. 



L. Griffithiana has a stipes 10 inches or a foot long, terminated by a simple 

 undivided frond 7 or 8 inches long by f inch broad. This, however, is but an unde- 

 veloped form of the foregoing, as was clearly proved by my finding at " Madrema- 

 cam " both forms on one stock, and numerous plants of intermediate forms : — and, 

 what is rather strange, the young seedlings are often bipinnate in an early stage and 

 become simpler afterwards. 



Lindsaya Lobbiana, hardly, if at all, ilistinct from L. cultrata, is also found in 

 the same small paradise of Ferns. 



Adiaxiuji,- L. 

 The indusia of this genus open inwardly, being formed, in fact, by a portion of 

 the edge of the frond turned back so as to cover the marginal sori ; they are either 

 distinct, or confluent and continuous. 



A. Paeishii, Hooh. 



This is a most interesting discovery. Until it was found only one species of 

 Adiantum was known to exist, which had an absolutely undivided frond : — this was 

 A. reniforme, a Madeira and Tenerifl'e jdant. My plant is thus described. AVholo 

 height 1 to 2 inches, tufted, i.e. with stii)ites growing all round a common central 

 axis, as opposed to those ferns which have creeping root-stocks and throw up fronds 

 here and there from it. "A few fibrous tomentose radicles descend into the soil, 

 and, from the summit of these, at the dry season of the year, are seen little else but
