New Species op South American Plants 73 



of leaflets, the basal pair on the lower branch 3-foliolate. Ulti- 

 mate segments from 3 to 6 cm. long, 1.5 to 3.5 cm. broad, ovate 

 with rounded to truncate, occasionally inequilateral base and 

 abruptly acuminate acute summit, sharply and sparsely ser- 

 rate,' very thin, the venation obscure. Umbels crowded in ter- 

 minal corymbs with short, very thick, bracted branches, about 

 2 cm. broad, on slender peduncles 3 to 5 cm. long, the bracts 

 of the branches broadly ovate, thick and corky. Pedicels 

 crowded, slender, about 3 mm. long, bracteolate at the base. 

 Flowers 4 to 5 mm. long and broad, the calyx about one-third 

 ■of the length, crateriform, minutely toothed, dark, the petals 

 very lightly imbricate. 



"A tree to 40 feet or more, occasional in forest below 1500 

 feet. Flowers white, in March or April. Inflorescence of 10 

 to 20 short branches crowded together to form a large cluster. 

 Leaves deciduous about the time of flowering, three times 

 pinnate, some of the final segments divided or pinnate. Col- 

 lected near Masinga, 250 feet, March 22." (Herbert H. Smith, 

 'Colombia, No. 1595.) Very near Balansa's No. 3758. 



Hydrocotyle grossulariaefolia. 



Stems very slender, creeping, regularly sulcate, the ribs and 

 ■grooves rounded. Petioles slender and weak, 2 to 6 cm. long, 

 striate, sparsely pilose below, densely so toward the summit, 

 the hairs reflexed. Blades 4 to 6 cm. broad, 2 to 3 cm. from 

 petiole to summit, strongly and broadly cordate, 5 to 7-lobed, 

 the lobes broadly ovate, obtuse or acutish, lightly 3-lobed and 

 coarsely and obtusely serrate, the sinuses acutish. Leaves 

 thin, pilose on the veins underneath, the upper surface with a 

 few scattered minute short trichomes. Peduncles filiform, 

 some longer, others shorter than their petioles, more or less 

 pilose, the umbels spherical, loose and open, about i cm. broad 

 in flower, very little more in fruit, then dense. Pedicels very 

 slender. Flowers scarcely 0.5 mm. long and nearjy as broad. 

 Fruits 2.5 mm. long, 4 mm. broad, strongly ribbed, both ribs 

 and grooves obtuse. 



Species near H. Poeppigiana, but differing in the form of the 

 leaf-lobes and especially in the angled fruits. 



" Diffuse, rooting, 3 to 4 feet, covering the ground on wet 

 banks in open land. Sierra del Libano. One specimen at 

 7,000 feet, February 26, another from near Valparaiso, 5000 

 feet, January 20." (Herbert H. Smith, Columbia, No. 1316.) 



Gaultheria sanmartansis. 



Glabrous. Branchlets elongated, slender, angled, pale- 

 ;green, densely leafy, the leaves imbricated, at length divaricate
