114 FLORA OF ST. CROIX AND THE VIRGIN ISLANDS. 



971. Oncidium Lemonianum, Lindl. 



Fl. May-July. Never giving fruit, but propagating itself by pro- 

 ducing young plants from buds in the axils of the sterile bracts below 

 the flowers, which remain in connection with the parent plant, and thus 

 often forming long colonies of plants from one tree to another. In for- 

 ests and thickets, gregarious, but rare. St. Thomas (Picara Peninsula, 

 Fortuna). 



(The lateral sepals in my specimens being distinct, I am inclined to 

 retain Lindley's specific name instead of uniting my plant with 0. tetra- 

 jyetalum, W., as done by Grisebach.)

Fl. July-Octb. On rocks and trees in shady places, not uncommon. 

 Virgin Islands.

 hills, not uncommon. Virgin Islands.
