the most coming from Tuxpan. I have seen no specimens of this 

 species. Mr. K. \V. Nelson, who is familiar with the tree and its dis- 

 tribution, tells me that it comes from the humid tropics and is likely to 

 be distinct from either of the above and from the Yucatan species 

 (G. odorata). It is not unlikely that this species may be the little known 

 G. anguatifolia or the very doubtful G. mexicana, M. C. do Candolle 

 writes me that G. mexicana can not be determined from the description. 

 The type locality, however, is known, and by this the species may yet 

 be made out. 



The North American species maybe noted as follows: 

 Cedrela occidentalis C. DC & Rose, sp. nov. 



Tree 15 to 20 meters high ; the trunk 6 din. in diameter; leaven rather variable, 2 to 

 8 dm. long; leallots (> to 20 pairs, variable, oblong and obtuse to lanceolate and 

 shortly acuminate (acumen either acute or obtuse), base unequal and acute on shorter 

 side, rounded or subacute on the other side, 5 to 18 cm. long by 2.0 to 7 cm. broad, 

 glabrous above, at first pubescent (as is also the rachis), beneath becoming glabrate ; 

 inflorescence a broad open panicle often 1 dm. long, glabrous; pedicels very short; 

 calyx 2 mm. long, 5- toothed; teeth broadly ovate, subacute, as long as the tube, 

 glabrous or nearly so ; petals 6 mm. long, obtuse, whitish-pubescent without; sta- 

 mens glabrous, anthers not apieulate at top; column 2 to 3 mm. long, longer than 

 the ovary; style shorter than the (glabrous) ovary; capsule 25 to 30 mm. long. 



Collected by J.X.Rose at Acaponeta, .June, 1897 (No. 1438); by Dr. E. Palmer at 

 Tepic, 1891-92 (No. 18<J4) ; and by E. W. Nelson at San Bias, 1897 (No. 4343), and Rosa 

 Morada, 1897 (No. 4357) — all in the Territorio do Tepic. 



Cedrela oaxacensis C. DC. &. Rose, sp. nov. Cedrela montana mexicana C. DC. 

 Monogr. Phan. 1:711. 1878. 



A small tree; leaflets 6 to 7 pairs, opposite, very shortly potiolate, oblong, 5 to 12 

 cm. long, 3 to 4.5 cm. broad, truncate at base, shortly acuminate and obtuse, nearly 

 glabrous above, softly pubescent beneath; inflorescence abroad terminal panicle, 

 much longer than the leaves, glabrous; calyx glabrous, or nearly so, 5-toothed; 

 sepals obtuse; petals I mm. long, reddisli pubescent above, grayish below; column 

 rather short ; style short. 



This species is distinct from C. montana, which comes from Venezuela. According 

 to Do Candolle it was collected first near Oaxaea by Andrieux, and more recently 

 near the same locality by C. (J. Pringle, August 15, 1894 (No. 4802), Lucius C. Smith, 

 July 20, 1899 (No. 79), and J. N. Rose, Jnne 17, 1899 (No. 4604). 



The following key to the North American species may serve to distinguish the 

 species until fuller collections may warrant a recasting of the descriptions:
