214 CONTRIBUTIONS FEOM THE NATIONAL HERBARIUM. 



Pentstemon dasyphyllus A. Gray in Torr. Bot. Mex. Bound. 112. 1859. 



"Stony hills of the Pecos, and Cook's Spring," Wright 1478. 



The first of these localities is in Texas, the second in New Mexico. From Doctor 

 Gray's statement I take it that both collections were distributed under the same 

 number in spite of the fact that the two localities are more than 150 miles apart, such 

 being a common practice of his. 



Pentstemon fendleri Torr. & Gray, Pac. R. Rep. 2: 168. pi. 5. 1855. 



"On the Pecos and Llano Estacado," Pope in March and April of 1854. 



If Pope's collection is the type the plant probably came from Texas; there is a bare 

 possibility that it was collected in New Mexico. Doctor Gray in the Synoptical 

 Flora considered this a synonym of P. acummatus Dougl. Doctor Krautter gives it 

 as a synonym of P. nitidus Dougl. It is probably distinct from both. 



Pentstemon linarioides A. Gray in Torr. Bot. Mex. Bound. 1 12. 1859. 



"Organ Mountains," Parry; also "Copper Mines and Las Animas," Wright 1472; 

 Thurber 331, 1115. 



Not infrequent in the Organ Mountains at the lower elevations, flowering in spring 

 and early summer. 



Pentstemon metcalfei Wooton & Stand ley, Torreya 9: 145. 1909. 

 A new name for /'. puberulus Woolon & Standley. 



Pentstemon pauciflorus Greene, Hot. Gaz. 6: 218. 1881. 



"On a bluff of the Gila River, in the extreme southwestern part of New Mexico near 

 the border of Arizona," August 30, 1880, E. L. Greene. 



Doctor Krautter places this as a synonym of P. lanceolatus Benth. The statement 

 that the type locality is in "the extreme southwestern part of New Mexico" is hardly 

 correct, for the Gila flows from New Mexico into Arizona about 100 miles from the 

 southwestern corner of New Mexico. 



Pentstemon puberulus Wooton & Standley, Bull. Torrey Club 36: 112. 1909. 



=Pentstemon metcalfei Wooton & Standley. 



"On shady slopes at the Lookout Mine, Sierra County," May 2, 1905, O. B. 

 Metcalfe 1605. 



Pentstemon thurberi Torr. Pac. R. Rep. 7 3 : 15. 1857. 



= Leiostemon thurberi-(A. Gray) Greene. 



"Burro Mountains," August, 1854, Dr. Thomas Antisell. 



This seems to be the type locality; but Thurber's plants were collected in Sonora. 

 Doctor Greene, very properly it seems to the writer, makes this the type of a new 

 genus, for the group of plants to which it belongs is very different from true Pentste- 

 mon. This species has been considered by some a subspecies of P. ambiguus Torr. 



Pentstemon virgatus A. Gray in Torr. Bot. Mex. Bound. 113. 1859. 

 "Santa Rita del Cobre, on the mountains, " Bigelow, Wright 1476 in 1851. 



Pentstemon whippleanus A. Gray, Proc. Amer. Acad. 6: 73. 1862. 

 "Arroyas in the Sandia Mountains," Bigelow in 1853. 



Scrophularia coccinea A. Gray in Torr. Bot. Mex. Bound. 111. 1856. 



"At the base of a rocky ledge near the summit of a mountain, Santa Rita del Cobre," 

 Wright 1470 in 1851. 



A very rare plant, collected only once since 1851, apparently, by Mr. O. B. Met- 

 calfe in this same region in 1904. His collection was distributed as a new species under 

 Doctor Greene's approval, but the latter has never published the description of the 

 new species.
