(7) A. reticulatum Kaulf. Fronds 15 to 50 cm. iii;.'li, mostly about one- 

 tenth as broad, exceedingly variable, broadest in tin- middle or near the 

 apex, gradually or abruptly contracted to an aemninatc or merely subacute 

 apex, attenuate below to a sessile base, or (in Pliilippine specimens) short 

 stalk, thin-coriaceous; costa black or green, usually visible for a few cen- 

 timeters into tlie frond, sometimes wanting, venation very evident; sori 

 jisually copious and anastomosing, rarely sparse, or even reduced to two 

 lines on each half of the lamina. This is our commonest Antrophyum, and 

 in one or another of its forms approaches almost all the other species. Our 

 conunonest form is A. fulratum Bl.. which is shorter-stalked than the type, 

 but not really distinguishable. A. Cumingii Fee, Cuming 416, also col- 

 lected in southern Luzon by Baranda, is likewise inseparable from it.
