purpurea, vexillo rotundato-cordato cucullato. — Arkansas, at the cross- 

 ing of Red River, Dr. Newberry ; New Mexico, Mr. Dieffendorfer 

 (ex T. C. Porter), J. T. Rothrock. Much branched, apparently a 

 foot or less in heiglit, bearing numerous spikes on slender peduncles : 

 leaflets about half an inch long : spikes at first white with the silky 

 down, in age fulvous. 



•^ Galiuji angulosu.m. Fruticosum, patenti-ramosissimum, hispi- 

 dum ; ramis insigniter costato-o-7-angulatis ; foliis crebris sublineari- 

 oblongis fere eveniis, cpsta subtus prominula, caulinis 5-7-nis (lin. 

 3-4 longis), ramulorura 4-6-nis paullo minoribus, ultimis florem brevi- 

 pedunculatum fulcrantibus conformibus ; corolla flavescente ; fructu 

 ut yidetur carnosulo vel baccato fere Itevi. — Guadalupe Island, on 

 rocky precipices in the middle of the island, Dr. E. Palmer. This 

 species seemingly belongs to the Relbuniiun section ; but only forming 

 fruit was collected ; its surface is obscurely granulate. The leaves 

 on the crowded and divaricate branches are as long as the internodes 

 or longer ; and the ultimate whorl and its interuode are just like the 

 preceding ones, in which respect it diifers much from G. Relbun and 

 its near allies. The numerous ribs to the stem are remarkable, and 

 tiiey are visible even on portions that have become woody. 



' Brickellia mickophylla Gray, var. scabra. Foliis parvulis 

 rigidioribus papilloso- vel Iiirtello-scabris ; pappo tantum 16-20-cha;to. 

 — Rocks, Southern Colorado, Dr. Parry, T. S. Braudegee in Hay- 

 den's Exploration, 1875.

 nunc in paniculam effusam ramulosam solutis ; foliis filiformibus (pol- 

 licaribus, fasciculorum brevioribus) parum punctatis ; involucro tur- 

 binato, squamis lato-linearibus chartaceis graiuiloso-subglandulosis 

 apicem obtusissimum versus fimbriolato-ciliatis ; ligulis 3-4 flores disci 

 11-15 baud superantibus ; acheniis breviter linearibus villosulis. —
