﻿83. CHEIROPLEURIA. 733 



lanceolate, simple, narrowed towards both ends, with ± 3 prominent ribs, on 

 stipes 45 c.M. or more long. 



War. integrifolia : Barren fronds ovate-acuminate, simple.

8G«. LEPTOCHILXJS, Uaulfuss. 



Sporangia densely crowded over the under surfaceof the contracted fertile 

 fronds or pinnae of fertile fronds. Paraphyses mostly small or wanting. 

 Spores generally bilateral or ellipsoidal, often purveyed with more or less 

 deciduous, elevate, reticulate, entire, plicate or fimbriate membranes. 



Rhizome generally creeping. Stipes not articulate to the rhizome. Fronds 

 dimorphous, simple or pinnate; veins anastomosing copiously, + as in Aspi- 

 dium, very rarely as in Nephrodium; areolae generally with included free 

 veinlets. 



Pan tropical. 



Arrangement of the sections. 



§ 1. POECILOPTERIS (Gymnopteris). Main veins distinct nearly or quite to 

 the edge. Hk. Bk., Syn. Fil, tab. VII, fig. 60, v— x, aa— bb; Diels, in 

 Engl. & Prantl, Nat. Pfl.Fam., I*, fig. 106—107. 



§2. CHRYSODIUM. Main veins wanting or indistinct. Fronds simple or 

 ternate, the segments not articulate to the rachis. Hk. Bk., 1. c, i]g. 

 60, y-z. 



§3. LQMAGRAMMA. Like § 2, but the fronds pinnate, the segments articu- 

 late to the rachis. (*) 



§ 1. POECILOPTERIS 



a. Barren fronds typically simple and entire, but some of them sometimes ter- 

 nate or quinale. 

 §. Veins anastomosing in costal arches only, the rest free. 



(1) L. oligodictyusi 

 $.$. Veins anastomosing copiously.
