58 New Species of South American Plants 



slender, narrowly grooved. Blades lo to 13 cm. long, 4 to 5 

 cm. broad, obovate, with acute base and a very abrupt, short, 

 narrow and acute point at the summit, thin, lightly and un- 

 equally serrulate, some of the teeth rounded and some minutely 

 pointed, above deep-green and sub-glabrous, with the venation 

 slightly prominent, underneath pale, pilose on the veins and 

 becoming nearly glabrous, the venation prominent, the prin- 

 cipal secondaries about 8 on a side, strongly falcate near the 

 midrib, then strongly ascending and disappearing in the mar- 

 gin, connected by very numerous straightish tertiaries. Pan- 

 icles long-peduncled, short and broad, densely flowered, the 

 bracts small, linear, or lance-linear, the flowers mostly short- 

 pedicelled, the pedicels slender, the inflorescence short-pilose 

 and scurfy, slightly ferruginous. Flower i cm. broad, the 

 sepals and petals sub-rotund, the sepals about half the length 

 of the petals. Stamens numerous, the longer about equaling 

 the petals. Ovary globoidal, about i mm. long, lightly 4- 

 grooved, the styles 4, distinct, much longer than the stamens. 



"A forest tree at Calagualita, 1500 feet, May." (Herbert 

 H. Smith, Colombia, No. 857.) 



Species near vS. pedunculata H. B. K. 



Clusia oblanceolata. 



Glabrous, the branchlets stout, angled, brown, rough with 

 leaf-scars. Leaves 15 to 20 cm. long, 3 to 4 cm. broad, the 

 petioles only about 2 mm. long, 3 mm. broad, the base of the 

 oblanceolate blade narrow and cordate, the summit abruptly 

 short-pointed and obtuse, the margin entire, thinly revolute, 

 brownish, the midrib prominent on both surfaces, deep-brown 

 underneath, the secondaries very numerous, slender, parallel, 

 slightly falcately ascending, the texture thickish and coriaceous. 

 Raceme terminal, strongly peduncled, few flowered. Only 

 pistillate flowers seen. These long and stoutly pedicelled, 3 or 

 4 cm. broad. Bracts 2, rotund, about 12 rnm. long. Petals 

 and sepals similar, the petals narrower, obovate with narrowed 

 base, nearly 2 cm. long. Staminodia numerous, distinct, tor- 

 tuous and somewhat matted, less than half the length of the 

 petals, some bearing small rudimentairy 2-celled anthers. Stig- 

 mas 5, very large, obovate with narrowed base, reflexed over 

 the staminodia and partly concealing them, coarsely and un- 

 equally lobed and lacerate at the summit. 



"A tree to 35 or 40 feet, common in mountain forest, 5,000 

 to 6500 feet. Collected about Valparaiso, 5500 feet, March
