 Very variable in the size of the fronds and in the length of the stipes ; best dis- 

 tinguished from G. axillaris by the very different caudex.

 Isle of Samar, Philippines, Cuming, n. 320 {in Herb. Fee, but that number in 

 our herb, is Gymnopt. normalis, J. Sm., our A. lanceolatum, 0). — Cuming's n. 326 

 would appear to include two s[)ecies. The present is the Leptochilus minor of 

 Fee, but is not the G. normalis, J. Sm.. which bears the same number of Cuming. 

 The present is the smallest species of the genus.
