Galium pubens : perenne, undique pube densa patente cinereum ; 

 caulibus (ultrapedalibus) adsurgentibus paniculato-ramosis inerraibus ; 

 foliis quaternis quinisve ovatis vel oblongis (lin. 4-6 longis) fere mu- 

 ticis uninerviis secus margines costamque magis hispidulis; cymulis 

 foliosis paucifloris, pedicellis fructiferis deflexis ; corollis albidis vel 

 carneis raro 3-5-fidis ; fructu ut videtur carnoso, immature- pubero. — 

 Yosemite Valley and adjacent mountains, Bolander, Torrey. The 

 specimens collected by the former have perhaps only male flowers, on 

 very short pedicels ; those collected by the latter have fertile flowers, 

 on pedicels mostly twice the length of the flower and fruit. The 

 pubescence, although soft and velvety to the touch, is hispidulous, 

 but not uncinate, although rather hispid on the margins of the leaves ; 

 the angles of the stem not at all armed or roughened. 



Galium Bolanderi : glabrum ; caulibus e radice perenni ramos- 

 simo diffuso (ultrapedali) ramulisque fere laevibus ; foliis quaternis 

 lato-linearibus uninerviis margine rariter scabro-hispidulis (3-5 lin. 

 longis) ; paniculis laxe floribundis ; pedicellis flore purpureo brevi- 

 oribus vel sequilongis ; fructu (immaturo) subgranulato glabro. — 

 Sierra Nevada, on the Mono Trail, Bolander. — Flowers small : the 

 corolla only a line or a line and a half in diameter, apparently deep 



dull purple. 



Galium acutissimum : scabrido-puberulum, inerme ; caule gracili 

 ramoso ; foliis quaternis (lin. 3 longis) ovato-lanceolatis seu lanceolatis 

 valide uninerviis sensim in cuspidem rigidum acuminatis ; cymulis 

 paucifloris ; floribus albis brevissime pedicellatis ; ovario glabro. — 

 Between the Rio del Norte and New Mexico, Dr. Newberry. A very 

 small-flowered species, remarkable for its gradually attenuated, cuspi- 

 date, rather rigid leaves. 



Brickellia incana : tomento implexo (aetate subdeciduo) de- 

 albata; foliis ramorum alternis subcordatis vel ovatis sessilibus fere 

 integerrimis basi subtrinervatis ; capitulis ramos terminatibus breviter 

 pedunculatis multifloris ; involucri pluriserialis squamis obtusis, ex- 

 timis ovatis, intimis linearibus ; acheniis sericeis. — Providence Moun- 

 tain, in the Mohave district, 1861, Dr. J. G. Cooper. Only a single 

 specimen, which wants the lower part of the stem. Leaves rather 

 thin, the largest present less than an inch long, those on the flowering 

 branchlets barely half an inch long. Heads single on the branchlets, 

 even larger than those of B. lanata (an inch long, very many-flow- 

 ered), the down finer and whiter, completely hiding the veins.
