united by arched and angled transverse veins and these again 

 connected by longitudinal ones {i. e. parallel with the costu- 

 lar) thus forming costular areoles again reticulated or inclu-

 with a pale-coloured margin, — Gymnopteris, /. Sm. in Hook.

Hab. Luzon, Cuming, n. 225. Malay Peninsula, Sir Wm. Norris. — My speci- 

 men from Mr. Cuming is quite a pinnated one ; those of Sir W. Norris have pin- 

 nated and subsimple fronds ; but Fee's figure seems rather to represent the sterile 

 frond of a terminal pinna than an entire simple frond. 



§ 13. Leptochilus. — Only differs from the preceding section (§ Gymnopteris) 

 in the very narrow-linear or almost filiform fertile fronds or their pinnce. —

156. A. (Leptochilus) axillare, Cav. ; caudex very long 

 scandent flexuose here and there branched ; sterile fronds 

 rather distant (with very short stipites almost none or 1-2 

 inches long and stramineous) membranaceous 5-6 inches to 

 1 foot and more long \-\h inch wide lanceolate more or 

 less acuminate strongly costate entire gradually tapering 

 below and long-decurrent sometimes to the base of the stipes 

 and even auricled there ; fertile fronds (with stipites 3-4 

 inches long a little scaly at the base) 6 inches to a foot long 

 1-3 lines wide linear tapering at both extremities flexuose.

 base entire, costules indistinct, areoles with free veins ; 



fertile ones coriaceous a span to 1 foot long 2-6 lines broad.
