53. P. shastensis Greene, Plantae Bakerianae III. 1. (1901) 32. — Die Beschreibung 

 ist unvollkommen, enthält nur folgende Angaben : »Also [d. h. ebenso wie P. retrorsa Greene] 

 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 coriaceous, 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.« 



*) Der Name P. muscicola Rock kann bestehen bleiben, da Rock 1. c. am Schlüsse der Beschrei- 

 bung der Varietät bemerkt: Specimens of this variety have been distributed to herbaria as Plantago 

 muscicola. 



*) Bezieht sich wohl auf die dünnen Adventivwurzeln.
