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 height, bearing numerous spikes on slender peduncles : 

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

 down, in age fulvous. 



Galium angulosuai. Fniticosum, patenti-ramosissimum, hispi- 

 dum ; ramis insiguiter costato-5-7-angulatis ; foliis crebris sublineari- 

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

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

 pedunculatum fulcrantibus conformibus ; corolla flavescente ; fructu 

 ut videtur carnosulo vel baccato fere lievi. — Guadalupe Island, on 

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

 species seemingly belongs to the Relhuninm 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 intcrnodes 

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

 2)receding ones, in which respect it differs much from G. Relbun and 

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

 they are visible even on portions that have become woody.
