36 New Species of South American Plants 



the leaflets distinctly oblanceolate. The calyx is similar, but 

 the petals decidedly shorter. 



Cedrela Boliviina. 



Inflorescence sparsely and minutely canescent. Leaves 

 (only the uppermost seen) 5 dm. long, the petiole i dm_. long, 

 slightly grooved upon the upper surface, like the rachis, the 

 leaflets sub-opposite, 7 to 9 pair, the internodes about a third 

 as long as their leaflets. Petiolules very slender, about 6 mm. 

 long, articulating by a thin, disk-like base. Blades 8 to 16 cm. 

 long, 2.5 to 4 cm. broad, the lower successively smaller, lanceo- 

 late, with mostly obtuse or sub-rotund base and long-acuminate 

 summit, entire, thin, the slender venation lightly prominent 

 beneath, the secondaries 15 to 20 on each side, abruptly dilated 

 at the base, widely spreading, lightly curved and uniting to form 

 a thin, brown revolute margin, the remaining venation very 

 finely reticulate and faintly impressed on both sides. Panicle 

 (much broken in my specimen) apparently as long as the leaves, 

 distantly branched and very loose and open, the branches 

 elongated, divariacate or the lower declined, pedunculate and 

 loosely flowered, the flowers shortly and stoutly pedicelled,the 

 bractlets broadly ovate, acuminate or attenuate, longer than 

 the young buds. Calyx campanulate, 2 mm. broad and nearly 

 as long, lobed nearly to the base, the lobes rounded. Corolla 

 pilose, twice the length of the calyx, the upper petals very 

 thick. Disk 5-lobed. Filaments very slender, short, the 

 anthers oval, nearly as broad as long, compressed. Style 

 stout, the stigma discoid and peltate, very large. Staminodia 

 not apparent. 



"A tall tree at Cotana, near Ilimani, Bolivia, 2,450 M. alti- 

 tude, November 1911. (Otto Buchtien, No. 3199.) 



Trichilia oblanceolata. 



Glabrous, the branchlets rather stout, terete, very leafy. 

 Petioles (only the upper leaves seen) 2 or 3 cm. long, slender, 

 terete, bearing near the base one or more embryonic linear 

 leaflets, 7 or 8 mm. long. Normal leaflets mostly 5, the petiol- 

 ules of the lateral ones 5 to 6 mm. long, stout, lightly grooved 

 above, the blades of the upper pair about i dm. long and 3 or 

 4 cm. broad, oblanceolate with acuminate base and abruptly 

 acuminate and acute summit, thin, the slender venation prom- 

 inent beneath and faintly so above, the principal secondaries 

 10 to 12 on each side, strongly falcate and irregularly anasto- 

 mosing near the margin, the venation rather coarsely anasto- 

 mosing. The lower pair similar but only about three-fourths 

 as long. Panicles in the upper axils, shorter than their leaves, 

 short peduncled, the flowers rather dense at the ends of the 

 branchlets, the bractlets very small, ovate, acute, the flowers
