2. Rolliniopsis simiarum Safford, sp. nov. 



A small irregularly branching tree with small narrow round-pointed 

 leaf blades, 3-winged flowers, and dense clusters of small yellow aro- 

 matic berries. Young growth grayish-tomentulose, the branchlets 

 soon becoming glabrous, those of the vegetative growth slender, zigzag, 

 with reddish brown bark sparsely dotted with lenticels, those termin- 

 ating the limbs often irregular, with grayish bark, short internodes, 

 and prominent leaf scars. Leaf blades variable in shape, those at 

 the base of the branchlets smaller and relatively broader than the 

 succeeding ones; normal leaf blades oblong-lanceolate, rounded or 

 very slightly retuse at the apex, rounded at the base, 8 to 10 cm. long, 

 2.8 to 3.5 cm. broad, with 9 to 13 nerves on each side, membranaceous, 

 deep green above, paler beneath, yellowish green or olivaceous when 

 dry, apparently glabrous on both faces but as seen under the micro- 

 scope clothed with scattered minute curved whitish hairs; midrib 

 impressed above, prominent beneath, reddish brown, sparsely clothed 

 with grayish hairs; parenchyma between the lateral nerves divided 

 into polygonal areoles by fine reticulating veins; petioles broadly 

 grooved above, clothed at first with grayish tomentellum, those of the 

 normal leaves 6 to 8 mm. long, of the smaller leaves 3 to 5 mm. long. 

 Flowers (only the detached petals of one flower observed) reddish 

 brown when dry; petals laterally compressed, winglike, suborbicular, 

 abruptly contracted at the base, 11 mm. long, 9 mm. broad; calyx 

 persistent (observed only on dry fruits), 3-lobed, the divisions rounded 

 or obtuse at the apex, 2 mm. broad, 1.8 mm. high; peduncles (only 

 those of fruit observed) at length woody, 12 to 21 mm. long. Fruit 

 a cluster of small distinct sessile carpels borne on the indurated recep- 

 tacle; mature carpels aromatic, pyriform or obovoid, 8 to 12 mm. long, 

 5 to 6 mm. in diameter, rounded or abruptly beaked at the apex, 

 gradually narrowed at the base; pericarp glabrous, yellow when fresh, 

 dark brown or blackish when dry; seed solitary, obovoid or pyriform,
