seen, thin, soft-hairy on both surfaces, especially beneath, where 

 the venation is prominent, the secondaries about 20 on each 

 side, slender, little ascending and very little curved, connected 

 by numerous tertiaries. 



Specimen in young fruit, the peduncles 5 or 6 cm. long, 

 slender, somewhat quadrangular, the panicle bearing a basal 

 pair of long and slender branches, densely flowered at the ends, 

 the flowers sessile or very shortly pedicelled. Fruiting calyx- 

 tube turbinate, strongly annulate at the summit, by the base of 

 the limb, which is irregularly and shortly 5-toothed. 



Yungas, Bolivia, 6,000 feet, 1885 (Rusby, No. 2446). 



Distributed as " Chimarris, sp. n. " 



Lygistum tomentosum. 



Tomentose, the young branchlets more or less ferruginous, 

 the branchlets stout, with crowded leaves. Stipule interpeti- 

 olar, broadly deltoid-ovate, acuminate, nearly equalling the 

 petioles, ferruginous, like the inflorescence, petioles, etc. Leaves 

 very thick, 2 to 4 cm. long, 1.5 to 2 cm. broad, varying from 

 oblong to ovate, with rounded base and acute summit, the 

 finely reticulate venation strongly impressed on the upper sur- 

 face. Peduncle about as long as the petiole, stout, several- 

 flowered, the flowers shortly and stoutly pedicelled. Flowering 

 calyx 6 mm. long, the lobes about as long as the turbinate tube, 

 triangular ovate, acutish, thick. Corolla apparently deep 

 purple, the tube about equalling the calyx, the limb about as 

 long as the tube. Mature fruit 6 or 7 mm. long and nearly as 

 broad. 



"Growing in water at Unduavi, North Yungas, Bolivia, 

 3,300 M. altitude, December 2, 1907. (Otto Buchtien, No.

Gonzalagunia acutifolia. 



Pilose with appressed hairs and somewhat sericeous. Stip- 

 ules 4 mm. long, the base triangular-ovate, the summit seta- 

 ceous. Petioles 3 mm. long, slender, the blades 5 to 10 cm. 

 long, 2 to 3.5 cm. wide, ovate or lance-ovate and mostly a little 

 inequilateral, with rounded or blunt base and acuminate and 

 acute summit, thin, the venation not prominent, the secondaries 

 slender, about 7 on a side, strongly falcate-ascending, the vena- 

 tion coarsely reticulating, obscure. Spikes to i dm. long, very 

 loosely flowered, the fascicles sessile, i to 5-flowered, the flowers 

 very shortly pedicelled, densely long-pilose throughout, the 

 bracts narrowly linear. Tube of the flowering calyx i mm. 

 long, globose, the lobes about as long, subulate, erect-spreadmg, 

 later recurved. Corolla 4 or 5 mm. long, the tube narrowly 

 infundibular, the 4 lobes very unequal, lance-ovate, acuminate
