and 



branches strongly compressed. Leaves tap^ering at base almost to a pet- 

 iole, with the point nearly white. Flowers towards the summit of the 

 branches, commonly 5 — 7 on each branch. Petals obliquely" obovate, a 

 little longer than the stamens, with a tooth or angle near the summit. 

 Styles as usual, separating as the capsule maturte. Capsule 3 celled.

In the shape and size of the leaf this plant strongly resembles the H. 

 rosmarmifolium, it differs from it however widely in many respects; to 

 the IL Kalmianum it has a much closer affinity, but its flowers are not at 

 all corymbose, and I have found them invariably trigynous.
