A. cornea, Kidl. This was originally described from the draw- 

 ing of an inflorescence of a plant flowered in the Penang 

 botanic gardens and brought from the Lankawi islands 

 by Curtis. I found it very abundant on the limestone 

 rocks, where a few decayed leaves rested, in Perlis on 

 Bukit Lagi and Setul, on Bukit Eajah Wang. It is a small 

 sized species with a tuber rounded and flat topped about 

 2 inches across. The petiole of the leaf is about 14 or 15 

 inches tall, and half an inch through at the base, smooth 

 and of a dirty white color with dull Indian red longitudi- 

 nal blotches; there are two long close fitting sheaths at 

 the base. The blade has 3 branches, and is about 6 or 8 

 inches across, the leaflets are thin, light green, lanceolate, 

 ending on a long point, the largest one 5i inches long, 

 and \\-\± inch wide, the margins undulate, the nerves 

 meet in loops distant from the margin, the petioluls 

 short, are winged nearly to the base.
