20G Eastwood : New species of western plants 



This was collected on Mount Shasta, California, altitude 3120 

 meters, July 16, 1903, by Dr. Edwin Bingham Copeland, and dis- 

 tributed by C. F, Baker, being his number ^5/5, of 1903. 



It comes under the aggregate P. viscosnm Nutt,, to which it 

 seems closely allied, but as that has been an aggregate of many 

 different forms it seems unlikely that this from Mt, Shasta can be 

 the same as plants collected on the '^ Headwaters of the Platte." 



• Pentstemon Austin! sp. nov. 



Glabrous and pale-glaucous, stout from a woody stock, 5 cm. 

 thick, branching from the base, almost a meter high : lower leaves 

 oblong or ovate, on broad petioles as long as the blades, acute, 

 sharply denticulate ; upper leaves with shorter, broader petioles, 

 the uppermost meeting but not perfoliate : thyrsus virgate, 3-4 

 dm, long, the cymes 2-4-flowered, distinct : peduncles and pedi- 

 cels slightly and finely glandular -pubescent, the peduncles shorter 

 than the unequal pedicels : sepals ovate-lanceolate, pink on the 

 margins, 5 mm. long, slightly glandular, closely, longitudinally 

 veined : corolla rose-colored with the tube slightly longer than 

 the calyx, the throat abruptly dilated, 2.5 cm. long, slightly 

 glandular; upper lip of 2 rounded lobes of half its length, lower 

 with 3 spreading lobes, glandular within but not bearded : stamens 

 glabrous, anther-cells confluent and explanate ; sterile filament as 

 long as the fertile, scarcely broadening at tip, glabrous : earliest 

 capsules twice as long as the later ones, surpassing the calyx : 

 seeds irregularly angled, black, glossy, minutely papillate. 



Collected at Oak Creek, Inyo County, California, July 4, 

 1899, by Mr. S. W. Austin, in whose honor it is named, Number 

 lySj of the Death Valley Expedition, collected in the mountains 

 of Inyo County, is the same. It differs from P. spectabilis Thur- 

 ber, to which it is closely allied, by the simpler virgate inflo- 

 rescence, the shorter tube of the corolla, the less dilated sterile 

 filament, the anthers glabrous along the line of dehiscence instead 

 of ciliate, and the smaller corolla. P. flondus Brandegee is prob- 

 ably nearer, but it differs also from this in the distinctly petioled 

 radical leaves, the glaucous foliage, the longer tube of the corolla 

 and different shape of the lobes, the divaricately spreading divi- 

 sions of the anthers in bud instead of parallel ; the corolla is also 

 less ventricose below the opening.
