New Species of South American Plants 25 



Brunellia boliviana. 



Brunellia boliviana Britton ex Rusby, Mem. Torr. Bot. Club, 

 3 (1893), 13 is a homonym for B. Oliverii Britton, Bull. Torr. 

 Bot. Club 16 (1889): 160. At the time that I wrote the de- 

 scription for the new species, I inadvertently took up the wrong 

 herbarium sheet, namely Mr. Bangs No. 664, instead of Rusby's 

 2577i which has thus gone undescribed. I therefore now name 

 and describe the latter as follows. 



Brunellia Brittonii. 



Veins on the lower leaf -surf aces, calyx, etc. minutely puberu- 

 lent; branchlets elongated, very stout, coarsely angled, purplish, 

 ■containing a large pith; petioles 1.5 dm. long, very stout, cos- 

 tate; rachis in one of the two leaves seen 1.5, in the other 2.5 

 dm. long; leaflets about 6 pairs, their petiolules 2 or 3 mm. long 

 and about as broad, the blades i to 1.5 dm. long, 4.5 to 6 cm. 

 broad, oblong, inaequilateral and somewhat falcate, lightly cor- 

 date at the base, coarsely sinuate-dentate, very thick, very pale 

 ■and slightly shining above, with the midrib slightly impressed, 

 yellowish underneath with the midrib and 18 to 20 pairs of 

 crooked, lightly ascending secondaries terete and very prom- 

 inent, the prominent venation finely reticulate; peduncles 7 or 

 8 cm. long, very stout and coarsely and sharply angled; panicle 

 about 2 dm. long, nearly as wide, very loose and open, the stout 

 peduncle sharply 4-angled. Flowers sessile, only the staminate 

 seen. Sepals 6 mm. long and 3 wide, ovate, obtuse, thick and 

 fleshy. Filaments very slender, much exceeding the sepals, the 

 ■anthers large, stout, obtuse, versatile. 



Unduavi, Bolivia, 8,000 feet, October 1885 (H. H. Rusby, 

 No. 2577). 



Species very near B. boliviana, Britton, and distributed 

 ^nder that name. 



Weintnannia lyrata. 



Branchlets, etc., tomentose, the branchlets numerous, short, 

 angled, swollen at the nodes, the leaves crowded. Stipules 

 ■caducous, not seen. Leaves 3 or 4 cm. long, including the short, 

 stout petiole, ovate in general outline, of 3 to 7 leaflets, the 

 intemodes of the rachis broadly winged, the wing narrowed 

 •downward and with an angle on each side near the summit. 

 Lower leaflets smaller, 6 to 9 mm. long, oval, obtuse, obtusely 

 •serrate, the terminal 1.5 to 2.5 cm. long, ovate, serrate like the 

 lateral and somewhat incisely lobed or pinnatifid. Leaves 

 thick, sub-glabrous above, coarsely pilose bsneath, the venation 

 impressed above, prominent beneath. Racemes crowded at 

 the ends of the branchlets, 2 to 4 cm. long, slender, loosely 

 ilowered, the branchlets i to 3 flowered, the bracts minute, the
