Zahlhr., S.j'oliosus (iriseh., and S. nemoralls (jriscb., from which 

 it is distinguished by its subulate, spinulose-denticulate sepals; 

 more closely resembling .S'. hipaejormis reduncus Wimmer ined., 

 which has prominently reticulate leaves truncate at the base. 



e^ Siphocampylus fissus n. sp. 



Stem woody, twining, scabrously pubescent above, the inter- 

 nodes 5-10 mm. long, later lengthening to 2 cm.; peticjles stout, 

 4-6 mm. long, rough-pubescent; leaf-blades coriaceous, dark 

 green, shining above, broadly ovate-oblong, 20-27 mm- l«ng. 

 12-18 mm. wide, broadly rounded at the apex, truncate or broad- 

 ly rounded at base, subrevolute at the cartilaginous margin, 

 sharply and finely denticulate with subulate salient teeth (about 

 4 teeth per cm. of margin, 0.5 mm. long), glabrous and strongly 

 rugose above, brownish-green and scabrously pul;escent on the 

 veins beneath, the veinlets prominently reticulate; peduncles 

 axillary, 15 mm. long, densely pubescent, forming a leafy raceme; 

 hypanthium turbinate, 3 mm. high, 6 mm. wide when pressed, 

 densely puliescent; sepals erect, oblong, 1.5 mm. long, rounded 

 at apex, thinly pubescent, separated by broad flat sinuses; corolla 

 pale yellowish-green, the tube densely pubescent, 10 mm. long, 

 3-4 mm. wide when pressed, the lobes closely pubescent, nar- 

 rowly linear, the upper 23 mm. long, the lower a little shorter; 

 filaments equaling the upper corolla-lobes, glabrous below, pu- 

 berulent at the summit; anther-tube 10 mm. long, glabrous, the 

 two lower anthers penicillate. 



Type, Machride 4863, collected 16-24 June 1923, Playapampa, 

 Peru, altitude about 9000 feet, and deposited in the herbarium of 

 the Field Museum of Natural History (duplicate in herb, of 

 New York Botanical Garden). A relative of 5. Purdiaeanus 

 Planch, and 5. secundus Wimmer, as shown by the deeply cleft 

 corolla; differing from the latter in its broad blunt leaves and 

 pubescence and from the former in its small, rugose, shining 

 leaves.
