Chytranthus, Pancovia. 799 



fl. Dec, n. 6016«. — »An erect unbranched miniature tree; trunk often divided at 

 the base; leaves only at the extremities of the stems; flowers appearing all over the 

 trunk; calyx greyish-brown externally.« »Leaves about 60 cm long; leaflets 14 — 25 

 X 5 — 9 cm; petiolules up to 10 mm long; inflorescences 20 — 30 cm long; pedicels up 

 to at least 5 mm long; calyx connate for 2 — 3 mm with lobes 4x2 mm; petals 5 — 7 

 X 2,5 — 3 mm; stamens 5 — 5,5 mm long; ovary 3,5 mm in diam. with style 2 mm long.« 



»This species seems to be allied to Ch. setosus Radlk., from the Gameroons, which 

 has also a 6-locular ovary and petal-scales which are not joined to the petals by the 

 median ridge, which is characteristic of the genus. Both these species, and particularly 

 Ch. mayumbensis, approach the genus Glossolepis in their characters. The latter genus 

 has been distinguished by the greater number of stamens (12 — 15 in Glossolepis, 8 in 

 Chytranthus) and by the petal-scales, which are joined at the base and partly at the 

 edges, and provided with an extra flap or crest; while in Chytranthus the petal-scale 

 has a median ridge as mentioned above. Ch. Zenkeri Gilg is described, however, as 

 having up to 11 stamens, while Ch. mayumbensis has 12; Ch. setosus Radlk. and Ch. 

 mayumbensis both have petal-scales, which are free except at the base and margins. 

 The only distinction between Glossolepis and Chytranthus is thus the crest to the 

 petal-scale.«
