Flowers spicate or paniculate. Ovary hirsute 1. H. spicata. 



Flowers axillary. Ovary glabrous 2. H. Afzelii. 



Leaves 1 ft., narrowed below, hirsute on veins beneath. Ovules 



solitary S. H. macrojjhylla. 



Leaves under 8 in., at length nearly or entirely glabrous. 



Young leaves with deciduous tomentum above and below. Sepals 



obtuse; inner obovate or rotundate 4. H.foliosa. 



Leaves usually rounded, at the base, obsoletely puberulous and 

 dull above, sparsely pubescent beneath. Sepals from ovate-

 Leaves very coriaceous, oblong-elliptical or ovate-oblong, obtuse or acute, 

 rounded and sometimes narrowly subcordate at the base, broadly crenate- or 

 undulate-serrulate, dull or glaucescent and glabrous above, with reticulations 

 perceptible to the touch when dry, softly and densely hoary-tomentose be- 

 neath, 5-8 in. long, 2-3^ in. broad ; petioles \-\ in. Stipules pinnati- 

 partite, deciduous. Flowers in erect, terminal and axillary, simple spikes 

 2-4 in. long, or branched below and somewhat panicled 2 or 3 together in 

 the axils of pectinate bracts. Sepals ovate, tomentose externally. Petals
