This fine Begonia rec^uires similar treatment to B. conchcsfolia, 
previously figured, except that it delights in plenty of pot-room 
to bring its large glaucous foliage to perfection. I have again to 
thank the Eoyal Botanic Garden, Kew, for this addition to my 
extensive collection of this beautiful genus of plants. — W. W, S,
