32 PLANTS BAKERIAN^E. 



1901, C. F. Baker, n. 40. The plant so closely simulates, 

 habitally, the common but always more northerly E.pumilus, 

 that but for its very remarkable double pappus it would 

 have been let pass for that species. But upon examination 

 its pubescence is of another character, and the whole plant 

 is greener and more slender. 



PLANTAGINACE^;. 



PLANTAGO RETRORSA. Perennial, of the size and with the 

 habit of P. eriopoda, and with even a closely similar pubes- 

 cence^ but wholly wanting the fuscous woolliness, which so 

 conspicuously marks that species, the leaves not entire but 

 coarsely though sparsely runcinate-toothed below the mid- 

 dle : sepals much more herbaceous, and capsules more elon- 

 gated; seeds elliptic-oblong. 



Abundant in alkaline meadows at Doyle's, 28 June, n. 

 627. Excellently marked by the four characters indicated, 

 as distinct from the kindred species, with which it may 

 have been confounded, if before collected ; but the plant is 

 wholly new to me. 1 



NYCTAGINACE.E. ' 



ABRONIA BAKERI. Allied toA.fragrans, but much smaller, 

 and suffrutescent, the stems and branches, both the woody 



1 i P. SHASTENSIS. Also allied to P. eriopoda, and with definite traces 

 of its basal woolliness, but leaf -outline and leaf -texture very different, all 

 being comparatively thin, not at all ceriaceous, and the outline distinctly 

 obovate, the whole margin apt to be more or less repand-toothed : spikes 

 relatively short, and much more dense than in P. eriopoda; capsules almost 

 globose and not exceeding but even quite included within the calyx, the 

 sepals of which are largely herbaceous, and their narrow scarious margins 

 distinctly ciliolate all around : seeds oval. Species known to me only as 

 collected by myself on the plains of Shasta River in Northern California, 

 twenty-five years since. They were distributed for P. eriopoda, but are 

 now seen to represent something very distinct.
