Branches compres- 
sed ; leaves linear- 
lanceolate, acute, mu- 
cronate; flowers axil- 
lary and terminal ; 
leaves of the calyx 
unequal, linear lan- 
ceolate, as long as the 
corolla; petals tooth- 
ed near the summit ; 
styles 3, united. 
Shrub 2 — 4 feet high with a scaly bark, and with its numerous opposite 
branches strongly compressed. Leaves tapering 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 matures. Capsule 3 celled. 
In the shape and size of the leaf this plant strongly resembles the H. 
rosmarinifolium, it differs from it however widely in many respects ; to 
the H= Kalmianum it has a much closer affinity, but its flowers are not at 
all corymbose, and I have found them invariably trigynous.
