174 PENTSTEMON SECUNDIFLORUS. ONE-SIDED PENTSTEMON. 



more will be added to the list. The species now illustrated, 

 Pcntslcmou scciuidiflorns, was first found on the second expedi- 

 tion of Fremont, across the continent, in 1843-44, ^"<^ ^^'^s given 

 the name it bears by the eminent botanist Bentham, after an 

 examination of a dried specimen of Fremont's collecting from 

 Dr. Torrey's Herbarium, who published it in 1S45 '^^ the work 

 of De Candolle's, above cited. The genus is wholly American ; 

 one-third of the whole number known being native to California, 

 and most of the others being found in the drier parts of the 

 central regions of our country, chiefly in the W^ahsatch and 

 Rocky Mountain regions. The present species was found by 

 Fremont in what is now known as Colorado. It extends south- 

 wardly along the mountains of this State into Arizona, and prob- 

 ably into New^ Mexico, but has not been found outside of this 

 comparatively limited area, though a closely allied species, 

 Pcntstcmou acuminatus, and with which this was once confounded, 

 is found from Colorado across to California. The region of country 

 where this and kindred Pentstemons are found is very dry, and 

 the soil has a barren and parched appearance. Scarcely any of 

 the flowers found there have any fragrance; but a large number 

 are very showy, and give a gay feature to the scenery which 

 enraptures the traveller. The Pentstemons aid particularly in 

 the autumn beauty of this scenery, and especially the species we 

 now describe, which, together with the allied Pcnistcinon aciiiui- 

 iialns is one of those most frequently met with. It grows in 

 tufts, having several stems bearing flowers, and these are about 

 eighteen or twenty inches high. Mr. Lunzer's drawing is of a 

 fair average specimen, and from a plant brought by the writer 

 of this from South Park, Colorado. 



Many plants of the Rocky mountains, and regions further 

 west, do not thrive well in Eastern gardens ; but this one seems 

 to make itself quite at home. A plant has grown, without much 

 care, in an open, sunny place, from 1S73 to iSyS.when our draw- 

 ing was made. The lower portions of the root-stock, however, 

 in time become feeble, and it is best to take up and reset the
