12. Calyptranthes pullei Burret ex Amshoff, Rec. Trav. Bot. Neerl. 42: 4. 1950. 



A shrub or small tree to 8 m high, the young branchlets winged, the wing up 

 to 0.3 mm high, terminating distally at a node between the leaf-bases; plant 

 glabrous or essentially so, the young branchlets and the inflorescence sometimes 

 sparsely pubescent with appressed dibrachiate sessile reddish-yellow hairs to 

 0.3 mm long; leaves broadly elliptic or ovate, (1.5-) 2-3.8 cm wide, (2.5-) 3-5.5 

 cm long, 1.4—1.8 times as long as wide, rounded or obtuse at the apex, obtuse to 

 rounded or subcordate at the base, the margins abruptly decurrent on the petiole 

 which is 1-2 mm thick, 1.5-2.5 mm long. dark, abruptly differentiated from the 

 midvein on the lower surface ; midvein concave at the base on the upper surface, 

 plane near the tip, prominent beneath; lateral veins about 15 pairs, the number 

 indefinite, with numerous intermediates approximately equal in size ; marginal 

 vein 1-2 mm from the margin, about equaling the laterals and arched between 

 them, with a weaker submarginal vein beyond it ; leaves smooth and nearly con- 

 colorous, impressed-punctate above, marked beneath with 15-25 small dark 

 glandular dots per mm 2 ; inflorescence of paired panicles to 6-7 cm long, the 

 abortive axis up to 5-9 mm long, compressed, 2 mm wide, the panicles 3 times 

 compound, 30- to 40-flowered, the flowers mostly in 3's near the tips, the pe- 

 duncle 2-4 cm long, nearly terete, about 1.5 mm thick just below the lowest node ; 

 buds 2.5-3 mm long, obovoid to nearly globose, weakly apiculate or rounded at 

 the apex, turbinate at the base ; calyptra convex, 2 mm across ; open hypanthium 

 cup-shaped, prolonged 1 mm beyond the summit of the ovary, the orifice 2 mm 

 across ; style 5-6 mm long ; stamens about 150, the longest 4 mm long, the anthers 

 0.4 mm long ; petals none ; fruit not seen.
