Wild in Mexico ? — 



I have only seen one flower of this beauiiful plant , which might ai flrst siglii be 

 mistakftn for 0. Cervantesii. It is, however. readily known by its wingless column. 

 and especially by ihe very l.irge size of tbe yellow appendage. seated at the base of 

 ihe lip , which is scarcely shorler th.m the column. The flowers are pure wbile, 

 wiih rich crimson spots ot the base of all the six parls.

jjPseudobulbis ovoideo-oblongi?: rompressis 1-phyllis, folio oblongo 

 lanceolalo acutissimo; scapo 1 — 2-floro; floribus albido-coerulescentibus; 

 iabello cordalo, membrjnaceo, aculo, margine sinuoso, eroso ; gynoste-

Wild in Mexico— Galeotli. 



I have from M. Galeoiti, wiihout name, what raay possibly be tbis species. If so, 

 it resembles ihe preceding in its manner of growth, but the lip is ovate, repand. and 

 obiuse . and the sepals are three timcs as narrow as the pctals. In that case this 

 arid 0. rubesccns may have lo be uniicd; but the flowcrs of the laiier are much 

 smaller.

Wild in Nicaragua— Skinner. 



Remarkable among ihc white-lipped species for its fiowers being sufTused wiih a 

 teDder blush colour. The sepals nre very narrow. stroight and sharp-pointed. richly 

 spoited all ovcr wiih crirason. The petals are twice as broad, and have similar 

 spots. bui only near their base; ihe lip is spoiless, crisp, aiid cordalo.
