154 GYMNOGRAMME, § SYNGRAMME. 



a short distance from the margin where they unite by a series 

 of angular arches which constitute a zigzag line, sori most 

 beautifully and regularly arranged simple or forked clothing 

 the whole length of the veins but not extending to the con- 

 necting marginal arches. (Tab. CCC.) 



Hal). Borneo, Thos. Lohb. — A very pretty species, which I can nowhere find 

 described. 



59. G. (Syngramme) Borneensis, Hook. ; caudex creeping 

 the apex clothed with short black velvety hairs, stipites very 

 short scarcely 3 lines long pale-brown aggregated, fronds 

 simple coriaceous glabrous; sterile ones 4-7 inches long | of 

 an inch wide spathulato-lanceolate shortly acviminate ;/er/27e 

 ones 6-8 inches long scarcely j of an inch broad narrow 

 linear-lanceolate longer but more bluntly acuminate, all of 

 them gradually attenuated at the base nearly to the caudex 

 very minutely pellucido-punctulate, the margin narrowly sca- 

 riose serrulate towards the apex, the costa pale stramineous 

 beneath, veins copious subhorizontally patent simple or 

 forked united by a distinct longitudinal vein a little within 

 the margin, sori copious linear simple or forked extending 

 the whole length of the veins or more copious towards the 

 margin. (Tab. CCCI.) 



Hab. On trees, Sarawak, Borneo, alt. 2500 feet, Thos. ioii.— Evidently allied 

 to G. Lobbiana, but very distinct in texture, venation, and in the attenuated 

 base of the almost sessile fronds. 



60. G. (Syngramme) vittceformis, Hook. ; caudex creeping 

 partially clothed with setaceous black scales, stipites approxi- 

 mate subcsespitose 1-1 h foot long subflexuose purple-black, 

 fronds simple coriaceo-membranaceous 7-^2 inches long 

 |-2^ inches broad (in the sterile ones) shortly and ob- 

 tusely acuminate moderatelv attenuated at the base in the 

 fertile fronds long and narrow attenuated and decurrent on 

 the stipes, the margin subsinuato-dentate, veins copious very 

 patent simple or forked anastomosing into 2-3 series of 

 areoles only at the margin, sori narrow-linear occupying the 

 whole length of straight veins and extending partially to the 

 anastomosing ones. — Syngramme, J. Sm. in Hook. Lond.Jovrn.

 I have seen no specimens save from the above locality.
