New Species of South American Plants 55 



mens small, about two-thirds the length of the calyx-lobes. 

 Style short, stout, 



"A shrub 4 to 5 feet high, moderately common on open 



land, top of San Lorenzo Ridge, 7000 to 7500 feet, February 27, 



the plants then going out of flower." (Herbert H. Smith, 



Colombia, No. 1701.) No. 2758 is the same. 



Gay a rubricaulis. 



Yellowish gray-tomentsllate throughout. Stems nearly a 

 meter high, slender, erect, terete, branched at the top, the 

 branchlets slender, sub-erect. Petioles 6 to 10 mm. long, the 

 stipules 3 mm. long and broad, triangular, acuminate, per- 

 sistent. Blades 2 to 4 cm. long, 1.5 to 2.5 cm. wide, abruptly 

 deflexed, ovate with cordate base, the lobes rounded, and ob- 

 tusish summit, unequally and irregularly crenate-dentate, the 

 teeth and sinuses mostly obtuse, thickish, the venation slightly 

 impressed above, prominent beneath, 2 or 3 pair of secondaries 

 radiating from the base, one or two above on each side, con- 

 nected by a coarse reticulation. Peduncles axillary, in fruit 

 2 cm. long. Fruiting calyx 2 cm. broad, lobed about half-way, 

 the lobes broader than long, widely spreading, mucronate, the 

 point erect. Persistent central carpel-tube 3 mm. high, 5 mm. 

 broad, campanulate, many nerved, the nerves terminating in 

 short erect teeth. Petals nearly 2 cm. long, unguiculate, broad, 

 very thin and hyaline, finely nerved. Stamens 7 or 8 mm. 

 long, the free portion of the filaments nearly as long as the 

 united portion. Styles a little longer than the stamen-tube. 

 Fruit 10 to 12 mm. broad, 5 mm. high, the central cavity en- 

 closed by the carpel-tube, the apical filaments of the latter 

 attached to the summit of the carpels. Base of carpel 8 mm. 

 broad, the lower margin slightly indented, the upper portion 

 strongly incurved, obtuse. Seed about 1.5 mm. long and broad, 

 its inner margin about 1 mm. from the margin of the carpel. 



Specimen unique, collected in Bolivia by M. Bang, probably 

 near Cochabamba, without number. 



Malvastrum micranthum. 



Grayish-pubescent. Stems 3 dm. or more high, erect or 

 ascending with spreading branches, stout, coarsely angled, 

 sparingly leafy. Stipules 6 or 7 mm. long, lance-linear, acumin- 

 ate, thin, brownish, strongly nerved. Petioles sometimes ex- 

 ceeding 5 cm. in length, stoutish, sulcate. Blades 2 to 4 cm. 

 long, the breadth about the same, or a little greater, triangular- 

 ovate with truncate or slightly cordate broad base and rounded 

 summit, 3-lobed, mostly about half-way, the lobes irregularly 

 and rather coarsely crenate-dentate, the teeth mostly about as 

 broad as long, obtuse, the sinuses acute; thick, drying yellow-
