mainly from expeditions to the West Indies, and 998 by pur- 
chase; it will be seen that more than half of the plants 
secured during the year were obtained by gift. 
There have been prepared 620 herbarium specimens of 
cultivated plants, 230 from the conservatory collections and 
390 from those outside.
