Liebmannii: drawing and fragm. G) Cates in forests on 
slopes of mountains, “ terre froide,” Nov., Ghies reght 554 (TYPE 
of G. ovata: G.). — After careful comparison of the sketch and 
fragments of the type of G. Liebmannii in the Gray Herbarium 
with material of G. ovata, I have been unable to discover any dif- 
ferences between them which appear to substantiate the claim of 
the former to specific rank. Klatt’s species seems to have been 
based on a small and weak specimen of G. ovata. 
31. V. Princier Rob. & Greenm. Frutescent, 1-3.3 m. high, 
the stem tuberculate-hispid and glandular-granulose. Leaves 
mostly opposite, oval or oblong- or ovate-oval, obtusish to acutish, 
mucronate, rounded at base, pale green both sides, entire, very 
harshly lepidote-tuberculate both sides, 3-nerved above the base, 
strongly reticulate beneath, slightly revolute, 4-7.3 cm. long, 
3 cm. wide; petioles granular-hispidulous, 1-1.5 mm. long. 
Heads 3-15 in contracted cymose panicles at end of stem and 
branches, 2.5 em. wide; peduncles 1-2.5 cm. long; disk 8-12 mm. 
high, 1-(fruit)1.8 cm. thick. Involucre 5-seriate, graduated, 
6-8 mm. high, strongly radiating in fruit, the phyllaries stiffish, 
lanceolate to linear-lanceolate, narrow, mucronulate, slightly pale- 
margined, with thickened midrib, densely granular-tuberculate, 
hispidulous-ciliolate. Rays 10-12, oval-oblong, 12 mm. long, 
6 mm. wide; disk-corollas minutely granular-tuberculate, 4.6 mm. 
long (tube 1 mm.). Pales somewhat wing-keeled, granular- 
tuberculate at the colorate apex, 6.5-7 mm. long. Achenes silky- 
villous on margin, slightly so on sides above, 4 mm. long, 1.5 mm.
