Though not in all respects agreeing with the description 

 of L cuspidata given by Wight & Arnott, or with Wight's 

 tab. 741, I have no hesitation in referring to that species 

 the plant here figured. It differs from both figure and 

 description in the conspicuous snowy-white farina on the 

 stem and branches, which give it a very remarkable 

 appearance. There are several Peninsular, Indian and 

 Ceylon species, to which it is closely allied, and with 

 which it has been more or less confounded by Thwaites, in 

 his " Enum. Plant. Zeyl." by myself in the " Flora of 

 British India," and by Trimen in his *' Handbook of the 

 Ceylon Flora," all distinguished by the alternate exstipu- 

 late leaves, axillary one-flowered peduncles with no trace 

 of bracts or bracteoles, cymbiform lip abruptly narrowed 

 into the spur, and ellipsoid capsule narrowed (in a^^;) f5 

 both ends. Such are /. latifolia, Bot. Mag. tab. o6Zo
