﻿1%^ 79. STENOCHLAENA. § 1. LOMARIOPSIS. 



cuneate, slightly unequal-sided, the edge shallowly crenate but more deeply 

 towards the apex. Texture coriaceous; surfaces naked, upper dark-coloured, 

 lower paler; costae prominent on both sides, with the upper side tomentose 

 towards the base ; veins prominent beneath, the higher ones simple or forked, 

 the lower 2 X furcate or subpinnate, all united at the base by a prominent 

 costal line. Fertile fronds not seen. — The description is taken from a 

 specimen determined as Lomariopsis sorbifolia, Fee. 

 Amboyna (Teysmann).

Rhizome firm, wide-climbing, prickly, varying from slender to 5 m.M. 

 thick. Fronds scattered, the barren ones dimorphous. Normal barren fronds 

 stalked, 40 — 100 c.M. long, pinnate. Pinnae articulate, acute or acuminate, 

 entire, cuneate or rounded at the base, to 11 c.M. long, to SVj c.M. broad. 

 Texture firm and green (thin and reddish-purplish in S. gracilis, Kze); rachis 

 and costae often minutely scaly; surfaces naked. Abnormal barren fronds 

 variously divided, with very small, entire, crenate or incised, roundish, oblong 

 or linear ultimate segments, much smaller than the normal fronds and ad- 

 pressed to the substratum; texture membranaceous. Fertile fronds pinnate, 

 the pinnae narrowly linear. — The forms of this species are often considered 

 as forms of S. sorbifolia, J. Sm. or palustris, Bedd.
