about 20 on each side of the midrib, the secondary nerves and 

 reticulations lax, indistinct; petioles 1 to 1.5 cm long. Inflores- 

 cence terminal, corymbose, branched from the base, about 5 cm 

 long, 5 to 6 cm wide across the top, the branches mostly trichoto- 

 mous, pale-olivaceous, shining, subterete. Flowers numerous, 

 crowded at the tips of the ultimate branchlets, 5 to 7 on each 

 branchlet, sessile, the buds obovoid-obcuneate, about 4 mm long, 

 the calyx terete, brown and slightly rugose when dry, the throat 

 about 2.5 mm in diameter, the limb truncate, produced about 

 1.8 mm above the ovary. Petals wholly united into a deciduous 

 calyptra about 2.5 mm in diameter. Filaments numerous, 3 to 

 5 mm long.
