28 PLANTS FROM NEW CALEDONIA. 
et anticis et posticis; cellulis majusculis oblongo-quadratis striolatis. Foliola 
4-fida, disco cellulas 1-2 alto 12 lato, lobis basi cellulas 4 latis pinnatis, 
cruribus longis. 
Dimensions. Stems 1 to 2 inches long, diam. ‘3 mm. to ‘4 mm.; with 
leaves 1:5 mm. wide; leaves, dise ‘1 mm. to :2 mm. high x ‘4 mm. to ‘6 mm. 
broad, lobes *6 mm. long x:2 mm. wide at base, crura *3 mm. to "4 mm. long : 
cells ‘06 mm.x 04 mm. ; underleaves, dise *2 mm. high. 
Obs. Although this species agrees with Stephani’s description of the dise 
(2 mm. high x ‘4 mm. broad) and 6-lobate leaf-form of T. levifolia, the 
leaves are striolate, the plant not rigid but flaccid, and dull green in colour : 
the crura proceeding from all round the lobes give it a woolly appearance, 
which is noticeable in the dried specimens of the plant.

oribus, dense cæspitosa. Caulis a fronte compressus, sectione transversi 
cellulas interiores 20 x 20 transverse paulo elongatas, cellulas peripherieas 
parvas 50 exhibens, paraphyllosus, rigidus bipinnatus, pinnis alternis dissitis 
horizontalibus vel paulo ascendentibus, pinnulis in paria 5 dispositis, oppositis 
sensim decrescentibus. Folia geniculata erecta transverse vel paulo oblique 
inserta, caulina dissita arcte adpressa 4-lobata, lobis fimbriatis, disco cellulas 
4-5 alto 20 lato, cruribus capillaceis oppositis omnino lateralibus brevibus 
(cellulas uniseriatas 7-10 longis) sub-æquilongis (apicali paulo longiore); 
euticulà dense striolatä ; cellulis majuseulis quadratis vel oblongo-quadratis 
paehydermibus, trigonis nullis. Folia ramea arcte imbricata. — Foliola 
transverse inserta 2-3-lobata, lobis ciliatis sub-æquilongis, disco cellulas 2 alto. 
Planta mas tenerior ; andræcia e caule vel e ramis tenuibus orta ; bracteæ 
perigoniales in paria 4-5 dispositæ saccatæ, disco magno cellulas 4 alto; 
antheridia solitaria ovali-rotundata e stipite longo orta. 
Dimensions. Stems 1 to 2 inches long, diam. *3 mm. ; with leaves '5 mm. 
wide ; crura of leaves ‘4 mm. long; cells of dise ‘04 mm., ‘05 mm., of 
crura ‘07 mm.x:025 mm. ; underleaves, dise ‘4 mm. high; perigonial bracts 
-7 mm.x:35 mm. ; antheridia '25 mm.x:2 mm. 
Obs. Distinct from any of the few Trichocolewr recorded from Asia- 
Oceania. T. breviseta St. (New Guinea) and T. striolata St. (Luzon) have 
nude stems. The geniculate stem-leaves and the short subequal crura 
distinguish this species at once from any Trichocolee from Asia-Oceania.
