New Species of South American Plants 61 



deep-green above, grayish-green beneath, obsoletely serrate^ 

 the teeth few and very small, the venation prominent beneath, 

 the secondaries about 8 on a side, strongly ascending, connected 

 by numerous crooked tertiaries. Flowers solitary in the axils, 

 the peduncles 7 or 8 mm. long, erect, articulated to the calyx, 

 subtended by 2 pairs of whitish cartilaginous, ovate acute 

 bracts. Sepals 5, unequal, ovate, obtuse, herlsaceous, thin, 

 strigose, the lateral 9 or 10 mm. long, the others shorter and 

 broader. Lower petal 15 mm. long, saccate at the base, longi- 

 tudinally folded and slightly narrowed upward, falcately curved 

 so as to form a long stout beak. Lateral petals i cm. long, 4.5 

 mm. broad at the base, ovate, obtuse, the 2 upper of the same 

 length, long-unguiculate, the oval limb about twice the width 

 of the claw. Stamens sessile, 8 mm. long, the erect membranous, 

 appendages nearly as long as the anthers, obtuse. Two of the 

 anthers spurred, the spur 3 mm. long, blue, obtuse, nearly 

 straight. Ovary ovoid, obtuse, 3 mm. long, the stout style 4 

 mm. long, incurved, blunt or sub-truncate. "A small tree to 

 15 feet, in low damp forest, one mile from the coast, Don Diego,. 

 May 8." (Herbert H. Smith, Colombia, No. 2731.) 



Rinorea (?) dichototna. 



Glabrous. Arborescent, the branchlets slender, flexuous^ 

 terete. Petioles 4 or 5 mm. long, stout, narrowly margined^ 

 the blades 8 to 14 cm. long, 4 to 5 cm. broad, lanceolate with 

 obtuse base and acuminate obtusish summit, obsoletely serrate^ 

 thickish and rigid, bright-green, the very slender venation 

 sharply prominent underneath. Inflorescence once or usually 

 twice dichotomous, the common peduncle stout, 3 to 5 mm. long, 

 bearing one or more short, broadly ovate, acutish, thick and 

 rigid bracts, its branches similarly bracted, gradually elongating 

 as the flowers fall and leave crowded persistent stipes of the 

 pedicels, these stipes short and stout and terminating in a 

 brownish annulus or disk which is somewhat accrescent and at 

 length nearly twice as broad as its stipe. Pedicels about i cm. 

 long, slender, slightly thickened above, minutely pappillose,. 

 articulated to their stipes. Flowers about 8 mm. long. Calyx 

 open, the 5 sepals imbricate, broad and sub-rotund, the inner 

 somewhat larger. Corolla imbricate, the 5 petals erect, lanceo- 

 late, obtuse, thickish. Stamens 5, alternating with the petals, 

 distinct, about half the length of the petals, the filaments 

 longer than the anthers, broad, with pale margins, slightly 

 narrowed above, the anthers ovate, mucronate, the tip whitish. 

 Style nearly equalling the corolla, filiform, the lower portion 

 persistent, the ovary ovoid. Stigma terminal, minute. Young 

 fruit obovoid.

 Smith, Colombia, No. 1492-)
