VI. SOME NEW SPECIES OF MEXICAN AND NICA- 

 RAGUAN DICOTYLEDONS. 



By M. L. Fernald. 



Chlorophora mollis. Tree ; the branches covered with greenish 

 gray rough bark bearing many pale lenticels ; young branchlets cinereous 

 with soft fine pubescence : leaves ovate, subcordate at base, caudate- 

 acuminate at tip, 3 to 7.5 cm. long, 2 to 4.5 cm. broad, finely crenate- 

 serrate near the middle, and pilose on both surfaces, dull green above, 

 cinereous beneath, the nerves strongly oblique (making an angle of 

 30° with the midrib) ; the slender cinereous petiole 6 to 8 mm. long : 

 pistillate heads canescent-puberulent, 4.5 to 6 ram. in diameter, on 

 slender canescent peduncles 2 or 3 mm. long. — Oaxaca, Tomelliu 

 Cafion, June 23, 18'J9 {Rose 4" Hough, no. 4672). Differing markedly

 flowers. Staminate aments not seen.
