Terebinthua Longipea Rose, sp. nov. 



\ Bmall tree 3 to J meters high, with a smooth trunk an. 1 with a broad Hat t->p, 

 glabrous throughout; Leaves pinnate, 10 to 25 cm. long; common petiole terete, not 

 at all winged between the Leaflets; leaflets 3to6 pairs, on Blender petiolulee the 



longer 10 mm. long) long-acuminate, the terminal ones cuneate at base, tl then 



usually rounded, sometimes narrowed, always more or less oblique at base, 

 above, paler and somewhat reticulated below, quite glabrous on both ridel 

 when quite young; inflorescence paniculate, 10 cm. long; flowering pedicels I to - r > 

 mm. long, in fruiting 5 to 8 mm. long; sepals ovate, obtuse; petals white, oblong, 3 

 mm. long; fruit oblong, 12 mm. long, borne in a dense cluster. 



Type U.S. National Herbarium no. 346674, collected bj J. \ Rose and Walter 

 Hough "ii the dry hills above Matamoras, Puebla, June 26, 1809 (no. 4691 }. Also 

 collected by C. G. Pringle near Jojutla, Morelos, L901 (no. 8610). 



This species was not common about Matamoras, but was found scattered along the 

 brow of dry hills mingled with various Bpecies of Acacia. Mimosa, and < >pnntia. 



The type Rose's no. 1691 I is a fruiting specimen. The flower characters arc 

 drawn from Pringle' s no. 8510, which apparently belongs here although the leaves 

 are very immature. This species, while related to T. simaruba, is very different in 

 its habit of growth, inflorescence, foliage, etc. 



Terebinthus macdoug-ali Pose, Tonvya 6: 170. August, 1906. 



\ Bmall tree; hark of 1 an<l 2 year old branches reddish, smooth; leaves clustered 

 at the ends of short spurs, either simple or with •"» to 5 leaflets; rachie of compound 

 Leaves winged; petiole- short: blade oblong, obtuse, 1 to 1.5 cm. long, crenately 

 to. .the,!, with a very short,, dense pubescence on both Burfaces; male flowers home 

 in short racemes or panicles; sepals and petals densely pubescent; female flowers 

 solitary; peduncles very short, 4 mm. long, glabrous. 



A Bpecies common on the hills near the head of the Gulf of California, tirst 

 collected by Dr. E. rainier in L870 and recently collected near the same region by 

 l>r. I >. T. MacDougal, after whom I take great pleasure in naming it. 



This has heretofore been confused with B. hindsiana of southern Lower Calif ornia, 

 from which, however, it seems quite distinct. It differs in its more vigorous branches, 

 reddish instead of blackish bark on 1 and 2 year old shoots, Borneo hat thicker leaves 

 and leaflets, shorter and denser pubescence on leaves, more pubescent petals, etc.
