386 Ferns of British India and Ceylon. 



simple and sometimes anastomosing, or regularly anastomosing near 

 the margin, forming a continuous marginal vein, with one or more 

 series of marginal areoles ; fronds various, adherent to the caudex; 

 habit of Diplazium. 



i. Syngramme fraxinea. (Don. tinder Diplazium}) Rhizome 

 creeping ; stipes naked, glabrous, 1-4 feet long ; fronds 1-4 feet long, 

 simply pinnate with the pinnae a foot or rather more long, attenuated 

 at the base, stalked, and 2 inches broad, or bipinnate, the secondary 

 pinnae 3 inches long by f inch broad, sessile or subsessile with a 

 broad rounded base, in both forms finely acuminate, texture firm- 

 herbaceous, glabrous, or a little pilose beneath, entire or subentire, 

 or finely toothed ; veins very close, forked from the base near the 

 midrib, or much higher up, one or both of the branches often again 

 forked, rarely joining with the next group of veins ; sori running 

 along all the branches, but stopping far short of the margin. Dipla- 

 zium fraxineum, Don. Fl. Nep. 12-13. Gymnogramma javanica, 

 (Bl.), Bedd. F. S. I. t. 232, the pinnate form. F. B. I. t. 57, the 

 bipinnate form. G. serrulata, Bl. Pl.Jav. Fit. 113. Wall. Cat. 3 and n. 



Himalayas, from Chumba to Bhotan, 1,000-8,000 feet elevation, 

 very common ; Khasya, 1,000-5,000 feet elevation ; Ceylon, 5,000- 

 6,000 feet elevation ; Malay Peninsula, Tenasserim, &c. 



(Also in the Malay Islands ; South Pacific Islands, Africa and 

 Japan.) 



This Fern should certainly be associated with "Wallichii" and 

 " alismae folia," with which it quite agrees in habit, the anastomosing 

 of the veins is rare, but I detect it in all my specimens. 



2. Syngramme vestita. (Wall. Cat. 12.) Stipes tufted 3-6 

 inches long, wiry, more or less matted, the scales at the. base densely 

 tufted, silky; fronds linear, simply pinnate, 6-12 inch long, i-i| inches 

 broad; pinnae 7-14 on each side, in distant subopposite pairs, ovate, 

 stalked, entire, or often with an auricle at the superior base, texture 

 thick but flaccid, the rachis and both sides, but more especially the 

 under, densely coated with fine velvety ferruginous hairs ; veins
