Yungas, 1890 (629)— Mandon's 500; also collected at Pata by 
Pearce. Species near G. Zindleyi Hook. 
My specimen consists of one undeveloped leafy stem and the 
leafless fruiting summit of another, so that my description is 
necessarily incomplete and perhaps inaccurate as to size of leaves. 
ALLOPLECTUS SOLITARIUS SP. n. 
Glabrous, the branches coarse but weak, apparently partly de- 
cumbent or reclining, coarsely and obtusely 4-angled and sulcate, 
purplish ; leaves 1-2 or 3 dm. long, 5-10 cm. broad, oval, below 
abruptly acuminate into a long petiole-like base, the apex abruptly 
short-acuminate, acute, the margin serrate with very small rather 
distant teeth, the principal veins 7 or 8 pairs, much arched and 
continued along the margin; flowers solitary in axils from which 
the leaves have fallen, the pedicels slender, about 1 cm. long, much 
thickened near the calyx; calyx campanulate, gibbous, nearly 3 
cm. long, the tube small, turbinate, the limb membranaceous, 
strongly veined, purple, unequally lobed, the lobes very broad, 
ovate, obtuse or acutish, obscurely toothed ; two of the disk-glands 
large, the others more or less reduced; corolla deep purple, 3.5—4 cm. 
long, the tube cylindrical, nearly straight, the-throat not contracted, 
the móuth slightly oblique, lobes unequal, short, erect-spreading ; 
free portion of the filaments shorter than the anthers, which are 
broadened at the apex; ovary 6 mm. long, style stout, strongly: 
flattened. 
Songo, Nov. 1890 (856). 
ALLOPLECTUS, species certainly undescribed. 
My specimen is so badly eaten by insects that a description is- 
impossible. Yungas, 1890 (571). Also collected by Holton. 
COLUMNEA (SYSTELOSTOMA) BoLiviANA Britton sp. n. 
Minutely strigose the branches thick but weak, apparently 
decumbent or reclining, obtusely 4-angled and sulcate, light brown, 
glabrate; petioles about 1 cm. long, stout, strigose, the blades I 
and 
densely ‘pilose, 3 cm. long, curved, the base strongly gibbous on 
he upper side, the limb about equally ventricose on the lower 
side, the mouth oblique, the lobes equal, about 2 mm. long, 4 mm.
