Luzon, Cagayan Province, Bur. Sci. 7970 Maximo Ramos, April 20, 1909. - 
Luisia Ramosii is a stout plant, in habit similar to L. teretifolia. The lateral 
sepals are strongly keeled near the apex, the keel passing into an elongated, 
uncinate apicula. 
Three species of Luisia are now known to be natives of the Philippine Is- 
lands: L. valida Reichb. f., L. Foxworthyi Ames and the present one. Of these 
L. valida is not known to me. The description does not agree with any of the 
Philippine material I have examined, still its brevity leaves much to be desired.

This is a curious species composed of fleshy yellow-green roots 3-7 cm long, 
and filiform scapes. The minute flowers appear to open in succession. The 
lateral sepals appear to arise wholly from the lip and look like lateral lobes as 
their middle nerve continues from the base into the sae.
