Zuelania roussoviae ! Pittier, sp. nov. PLATE 79. 
A deciduous tree, 10 to 25 meters high, the trunk 30 to 50 cm. in diameter at the 
base. Trunk about 8 meters high; crown rounded. Bark grayish and rugged on the 
trunk and main limbs, reddish, smooth, and sparsely verruculose on the young twigs. 
Leaves on young shoots only. Petioles about 1 cm: long, pilose-pubescent. Leaf 
blade oblong, rounded at base, subacute, serrulate on the margin, pellucid-dotted, 
more or less pubescent above, hairy-tomentose beneath, 8 to 10 cm. long, 3 to 3.5 cm. 
broad. Stipules narrowly lanceolate, acute, about 6 mm. long, hairy, early caducous. 
Inflorescence of 10 to 15-flowered clusters, in the defoliate axils at the end of the 
branchlets. Interpedicellary bracts small, ovate-acuminate, scarious, hairy on the
