344 Scrophularinewe—Pentstemon. 
and a profusion of purplish carmine or violet flowers. Sepals 
serrate. There are several garden varieties, amongst them one 
having rosy flowers with a white throat. 
4. P. ovatus.—In foliage this species is extremely near 
P. diffusus, bat the corolla is more decidedly tubular, only 
slightly expanded at the mouth, and the lobes erect. Flowers 
deep violet-blue, slightly freckled. 
5. P. speciésus.— A handsome hardy species from 2 to 3 feet 
high with glaucous spathulate leaves and long narrow panicles 
of large intense blue bilabiate flowers, produced all the 
Summer. It is said to be variable 
from seed, rarely reproducing the 
beautiful tint of the wild form. Cali- 
fornia. 
6. P. Wrightit.—This is another 
good hardy species from 12 to 18 
inches high. Leaves glaucous, entire. 
Flowers of medium size, rosy carmine. 
Corolla broadly tubular, with a. wide 
mouth slightly irregular but not bila- 
biate. <A native of Texas. 
7. P. gentianordes (fig. 190).—A 
very beautiful hardy species from the 
high mountains of Mexico. It grows 
about 3 or 4 feet high, bearing long 
leafy panicles of bright violet-blue or 
scarlet and white flowers. This must 
not. be confounded with P. Hartwégit, 
which bears the same name in some 
gardens, and has rather smaller violet- 
blue flowers shaded with deep blue on 
the outside. The tube is shorter and 
more inflated. Possibly they may be 
varieties of one species, as they are 
both very variable under cultivation. 
8. P. pulchéllus——A showy but 
Fig. 190, Pentstemongentianoides. yather tender species with sessile 
(¥ nat. size.) 3 
linear-lanceolate serrulate glabrous 
leaves and secund racemes of rosy pink flowers sometimes 
tinged with purple. Corolla very much inflated, with small
