AERIDES. 



SVib-VSir.— Sander's (Gard. Chron. XXII. (18S4) p. 134), flowers pale

Aerides Laivrencecc was introduced by Messrs. Sander and Co.

sometimes quite exposed. It is often associated with Vanda

 larger flowers in which the purple spots are much brighter. It is 

 appropriately dedicated to Lady Lawrence, wife of the respected 

 President of the Royal Horticultural Society.
