1. CORDIA, L. 



Trees or shrubs often with cystoliths (best seen when dry) and a 

 maro-inal nerve in the leaves. FloAvers in 2-chotomous corymbose 

 cymes or clusters, ebracteate, polygamous. Calyx tubular or cam- 

 panulate, accrescent in fruit, teeth usually short, often n-regular. 

 Corolla tubnlar or funnel-shaped with 4-8 recurved petals, ^t 4-8 

 usually hairy at the base, anthers large exserted. Ovary 4-celied. 

 Style twice 2-partite. Drupe with a hard 1-4-celled putamen. beeds. 

 exalbuminous. 



The cystoliths appear as superficial discs on the dried leave.?, but Q^ature ^f,^^'^^ 

 are required for comparison of one species with another. Owing to the usual 

 absence of old leaves in herbaria and to my not having been able to collect tiowei s 



from the same trees as the mature leaves I am doubtful of some of the following 

 forms.

 lono- at the time of flowering, attaining 3-4" when mature, entire or

 mature scabrid with white discs when dry. Flowers small white with 

 calyx -12" long, corolla-tube included, petals 4 spreading oblong,
