ROSE MEXTCAX AXD CENTRAL AMERICAN PLANTS* 121 



once pinnate; leaflets 15 to 19, linear-oblong, 10 to 13 mm. long, 2 to 3 mm. broad, 

 gla])rous, entire, obtuse; fruit solitary on short reflexed peduncles, orbicular, glab- 

 rous, 3 lines long. 

 Type U. S. National Herbarium no. 801368, collected by J. N. Rose at San Juan 



Capi^trano, Zacateca?^, August 21, 181)7 (no. 2455). 



This species is nearest T. microphyUa (A. Gray) Rose and T. morelensis (Ramirez) 

 Rose, from both of which it differs in its more distinct leaflets, shorter peduncles, etc.

Terebintlius odorata (Krandegee) Rose. 



Burscra odorata Rrandegee, Proc. Cal. Acad. 11. 2; 138. 1889. 



M\\ Brandegee reduced this species to 7?. fayaroidcSy but a study of good material 

 recently collected by Nelson and Goldman convinces me that while its relationship 

 is evidently here it is clearly distinct.

In 1844 Bentham described from the Bay of :\ragdalena two species of Bursera 

 under the names Ehiphrium rhoifoliuin and E. 7undseaMu//i differing, as he states, oidy 

 in the number of leaflets, the former having 3 and the latter only 1. Dr. Engler in 

 his Monograph of the Burseraceao has reduced rhoifolia to a variety of hmheana 

 although the name rlffn/olia has precedence bypositi<m. There appears to be no 

 ground for maintaining both species and very little to support a subspecies. lihoifolia 

 should therefore be tlie nan:ie of the species and huuhama should either be consigned 

 to synononiy or takt^n u]) for a subsijccies if there proves to be one. Mr. Brandegee, 

 who has visited thu ty[.e locality, states that the number of leaflets varies from 1 to 9 

 and lie is therefore of the opinion that no variety should be retained, with which 

 oi)inion I am in accord. 



Terebinthus rubra Uose, sp. no v. 



Small trees or shrubs with smooth red trunks, tlie bark peeling off in broad sheets; 

 young branches and leaves glabrous; leaflets 5 to 7 pairs, lanceolate, rounded at base, 

 acuminate, serrate below, entire ab(n^c, paler beneath, 4 cm. long or less; flowers 

 not seen, but inflorescence apparently open; fruiting peduncle 1 to 2 cm, long, bear- 

 ing two to four fruits; fruit obovato, somewhat 3-anglcd. 



Only seen in southeastern Sinaloa in the foothills, where it seems to be common 



growing with 1\ teiiaifolia. 



Type U. S. National Herbarium 30052*), collected by J. N, Rose near Colomas, 



Sinaloa, July 14, 1897 (no. 1670). 



This species seems nearest T. jmnglei but has shorter petioles and peduncle and 



much broader leaflets, etc.
