smooth ; cells about 6-seeded.—I have seen but one specimen, and in fruit only. 
** Capsule crustaceous, rarely coriaceous, loculicidal on the crown only ; cells 
many-seeded ; seeds usually angular. Cymes sessile, capitate or few-flowered, axillary 
or terminal ; leaves glabrous or hispid, with one central nerve ; stipules with long 
bristles. —SCLEROMITRION, W. & A.

form of the leaves, but he deseribes these as glabrous, wheras they are distinctly 
seabrid in H. pinifolia; he further, by some error, quoted Miquel's Hedyotis rigida
