the nodes,” glabrous or nearly so; leaves petioled lanceolate to oval, dark 
glandular-dotted and slightly pubescent; panicle disposed in 3—5-flowered 
clusters; stamens 2. The narrowly obconical fruit evidently truncate, dis- 
tinctly 5-angled, ‘flowers small, purple ”.—Cienega, Arizona (588), along

short pubescent above; pistils and stamens exserted; stigma capitate; fruit 
terete, glandular at the apex. Dr. Torrey, in Bot. Mex. Bound. p. 172, 
thinks this may safely be assigned to B. scandens, L. So far as Choisy’s 
description of it goes, DC. Prod. vol. 13, pars 2, p. 454, I can see no reason 
why it should not, and have simply described it under this name, because 
it has been so. identified by my friend Dr. Gray—Head of the ‘“ Cienega”, 
Southern Arizona (590).
