New Species op South American Plants 45 



pitted in drying. Branches stoutish, terete. Stipules not 

 visible. Petioles to 2 cm. long, slender, narrowly grooved, the 

 glands minute, sessile, blackish. Blades 4 to 7 cm. long, 2.5 to 

 4 cm._ wide, oval of ovate with rounded, minutely apiculate 

 summit and minutely cordate rounded base, the margin bear- 

 ing very minute gland-like teeth; thick, roughish on the upper 

 surface, the venation slender, not conspicuous, the secondaries 

 about 6 on a side, nearly straight. Spike terminal, sub-sessile, 

 not much elongated, rather densely flowered, the pistillate 

 below, few, solitary, on very short, angled pedicels, the stamin- 

 ate crowded above, 2 or 3 together on filiform pedicels longer 

 thcin themselves and subtended by shorter subulate gray-hairy 

 bractlets. 



Staminate Flowers. — Sepals 2 mm. long, ovate, obtuse, thin. 

 Petals longer, lanceolate, obtuse. Stamens 15, on a long-pilose 

 torus, the filaments filiform, a little longer than the petals. 

 Disk 1.5 mm. broad, the lobes oval, partly adnate to the base 

 of the calyx. 



Pistillate Flower. — Calyx parted nearly to the base, the 

 lobes 2.5 mm. long, linear, obtusish. Petals none. Disk simi- 

 lar to that of the male flower, but larger. Ovary depressed 

 globose, densely long-pilose. Styles elongated, spreading, dis- 

 tinct, entire, the stigmas small. 



"A shrub, to 5 or 6 feet, in thickets on dry rocks on a hill 

 near the sea at Santa Marta, September 13." (Herbert H. 

 Smith, Colombia, No. 371.) 



Croton (§ Palanostigtna) ochromaefolius. 



Densely and coarsely yellow-scurfy and tomentellate. 

 Branches very stout, coarsely angled, the leaves crowded at 

 their ends. Stipules 6 mm. long, narrowly linear and attenuate^ 

 early deciduous. Petioles (only the upper seen) 1.5 dm. long, 

 6 mm. thick at the base, very stout, narrowly and deeply grooved 

 on the upper side, and bearing a pair of small black, globoidal 

 sessile glands at the summit. Blade 2 dm. long and nearly as- 

 wide, broadly and shallowly cordate, coarsely toothed when 

 young, then 3-lobed, and later 5-lobed, the lobes triangular- 

 ovate, acute, the sinuses acute or acutish, extending about a 

 third of the way, the margin closely beset with minute yellow, 

 gland-like tubercles or teeth. Leaf thick but not coriaceous, 

 roughish. 5-ribbed from the base, the ribs nearly straight, 

 stout, prominent on both surfaces, the secondaries of the midrib 

 about 7 on a side, widely spreading, little curved. Peduncles 

 shorter and stouter than the petiole, very strongly and sharply 

 angled. Spike becoming 4 dm. or more long and 2.5 cm. wide,, 

 the flowers distinct at the base, dense above, brownish-yellow, 

 the fascicles densely many-flowered, the pedicels at length about 

 as long as the flowers, stout, the bracts very small, linear, at- 

 tenuate.
