Blake — Five New Species of Cedrela. 109 



axils, evenly but not densely spreading-pilosulous along the secondary and 

 tertiary veins and veinlets, the lateral veins 13 to 20 pairs, prominulous 

 on both sides, the secondaries prominulous beneath, less so above; panicle 

 (imperfect) sordid-pilosulous, the axis zigzag, angled, the branches densely 

 floriferous from the middle; cymules about 3-flowered; pedicels mostly 

 less than 1 mm. long; calyx 2 mm. long, 5-lobed to middle, loosely and 

 sordidly tomentose-pilosulous especially toward margin, the lobes im- 

 bricated at base, suborbicular-ovate or deltoid-ovate, obtuse to acute, 

 thick-herbaceous with thinner paler margins; corolla in bud ovoid-oval, 

 blunt, thick, 6 mm. long, densely pilosulous-tomentose, griseous, along 

 the edges of the petals rufidulous; petals 5 (two exterior, two interior, one 

 with one margin exterior), oblong-oval, obtuse, pubescent within; column 

 in bud slightly shorter than pistil; stamens 5, glabrous, the subulate 

 filaments in bud 1.8 mm. long, the oval apiculate anthers 1.2 mm. long; 

 ovary subglobose, glabrous, 2 mm. long in bud, the thick glabrous style 

 1.2 mm. long. 



Type in the U. S. National Herbarium, No. 1023058, collected in the 

 vicinity of Quito, Ecuador, October 26 to November 1, 1918, by J. N. 

 Rose and G. Rose (No. 23571). 



Cedrela rosei is related to C. bogotensis Tr. & PL, of Colombia, but may 

 be distinguished by its puberulous branches, its larger leaflets, and its 

 thicker calyx. When the mature flowers are known they will doubtless 

 prove to be much larger, as the petals of C. bogotensis are said to be only 

 6 mm. long, while the buds of C. rosei are of the same length. 



Cedrela rotunda Blake, sp. nov. 



Tree; branchlets gray-green, striate, spreading-puberulous, glabrescent; 

 leaves abruptly pinnate, with 2 to 4 pairs of leaflets; petiole subterete, 

 spreading-puberulous, 2.3 to 6.5 cm. long; rachis similar, striate above, 

 4 to 12.5 cm. long; leaflets subopposite, on densely spreading-puberulous 

 petiolules 3 to 4 mm. long, the blades broadly oval to orbicular, the lower 

 4 cm. long, 3 cm. wide, the upper 6.5 to 11 cm. long, 4.5 to 9 cm. wide, 

 subequilateral, broadly rounded at each end or obtuse, sometimes emargin- 

 ulate, papyraceous, above light green, slightly lucid, rather sparsely 

 spreading-puberulous, glabrescent, beneath densely and softly griseous- 

 pilosulous with incurved hairs, the costa and the 4 to 6 pairs of chief veins 

 whitish and prominulous beneath, the costa impressed above and the 

 veins somewhat prominulous, the secondaries slightly prominulous above, 

 obscure beneath; fruiting panicle loose, pyramidal, glabrescent, about 

 25 cm. long and 18 cm. wide; fruiting pedicels stout, 8 mm. long; fruit 

 oval, obtuse, 2.5 cm. long, 1.4 cm. wide, fuscous, pustulate, dehiscing from 

 the apex, 5-celled; seeds obovate, 1.4 to 1.6 cm. long, 5 to 6 mm. wide,
