 3—4 mm longus, basi bracteolis geminis minimis ovatis vel sub-

L, tomentella gehort nach der Bestimmungstabelle von Dunn (Kew 

 Bull. [1910] 388) in die Nahe von L. micrantha Dunn und L. reticulata 

 Dunn (beide von Lagos), und diirfte besonders der letzteren nahekommen, 

 von der sie sich durch geringere Zahl der Seitennerven der Blattchen, 

 gleichmassige kurzfilzige Behaarung der Blattunterseite und kleinere 

 Bliiten mit trocken schwarzlicher Krone unterscheidet. Sehr nahe steht 

 unserer Art wohl auch L.vdutina Dunn in Kew Bull. (1914), 246 (Franz. 

 Kongo), bei der aber die Nerven der Blattchen 6-paarig sein soUen; 

 ausserdem sollen bei L. velutina die Stipellen 3—4 mm lang sein, wahrend 

 sie bei unserer Art ganz kurz sind.

Small or middle sized tree, with white or bluish 



glaucous twigs whose bark is usually somewhat thicker than in the 

 preceding; leaves pinnately or incompletely bipinnately compound; 

 leaflets usually smaller than those of the preceding, 3—11, usually 3—7 

 on fruiting branches and 5—11 on sterile shoots, leaflets rather thick 

 and veiny, dark-green above and paler beneath, glabrous on both sides 

 except on the veins of the lower surface, with rather densely pubescent 

 tufts in the angles of the principal veins; leaflets variously and irre- 

 gularly toothed and cleft especially the terminal and basal lateral which 

 are often again trifoliolate; secondary veins prominent and mesophyl 

 pale beneath; flowering and fruiting racemes usually 4 on a twig, oppo- 

 site in pairs, with numerous samaras, and at the ends of the twigs of 

 preceding years growth; racemes on short side branches 1 cm or less 

 in length, with or without reduced simple or ternate leaves; peduncles 

 2 — 2,5 cm long: samaras densely clustered, in appearance usually 

 smaller: samara wings joined usually at an acute angle at the base, and 



not at all, or not much attenuated; fruit body glabrous.
