A genus of inconspicuous, taper-leaved , rushy plants , with dingy green or pur- 

 plish or yellowish flowers. The species diff^er greatly in the form of ihe lip and ihe 

 proportions of ihe sepals and petais. They are iiot of t!ie least interest to cultiva- 

 tors ; the most remarkoble is L. volucris, found in Khasia by Mr. T. Lobb, which 

 does not appear to have been gathered by any other traveller. 



A species occurs on rocks on Mount Victoria in llong Kong, where it was found 

 by Major Champion (herb. Chamb. 526); bul it was nol seen in flower aad cannot be 

 identified. It may possibly be L. teres.
