A small genus, nearly confined to tropical Africa, India, and the intervening islands. The 

 following species appear to be all endemic, and confined to the west of the continent. 

 Mature leaves densely hoary-tomentose beneath. 



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



Mowers axillary. Ovary glabrous 2. H. Afzelii. 



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



solitary 3. H. macrophylla. 



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- 

 lanceolate to ovate ; inner obtuse 5. H. anyolensis. 



Leaves narrowed to the base, glabrous, except midrib. Sepals 



ovate-lanceolate 6. if. Planchoni. 



Leaves shining above. Inner sepals obcordate, apiculate ; outer 



with revolute margins 7. H. platysepala. 



1. H. spicata, Oliv. An extensive climber. Extremities about as 

 thick as a goose-quill, shortly tomentose-pubeseent or puberulous at first. 

 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 £-i 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

 above. Fruit globose, glabrous.

2. H. Afzelii, R. Br. ; Planch, in Lond. Journ. Bot. vii. 525. Brandies 

 hoary-tomentose. Leaves oblanceolate-oblong or -elliptical, shortly acumi- 

 nate, rather remotely serrulate or denticulate-serrate, at first with a deciduous 

 tomentum above, soon glabrous and shining, white or pale-tomentose be- 

 neath ; lateral veins with numerous, transverse, parallel veinlets, 3^-6 in. 

 long, 1J-1± i". broad; petiole about £ in. Stipules pinnatipartite or sub- 

 paknatifid ; segments subulate. Flowers in axillary subsessile fascicles, more 

 rarely pedunculate, shortly and closely racemose. Outer sepals ovate, 

 densely silky -tomentose where exposed. Petals spreading or recurved, obo-
