Pentstemon Thurberi : shrubby, much branched, very smooth; tube of the corolla very short, 
tubular-funnelform ; lobes of the limb ovate; sterile filament smooth. Burro mountains, New 
Mexico; August. This is No. 1056 of the collection of Mr. Thurber, who found it in Sonora 
and indicated to me the characters in which it differs from P. ambiguus. The tube of the 
corolla in the latter is nearly three-fourths of an inch long, and curved, while the whole length 
of the flower of the former is not half an inch. 
Pentstemon linarioides, Gray, Mss. Chiricahui mountains, New Mexico ; August. This 
species will be described in the botany of Capt. Whipple’s Pacific Railroad Report. It belongs 
to the section Cepscosmus, and is No. 1472 of Wright’s New Mexican collection, and No. 331 
of Thurber’s. 
Pentstemon centranthieolius, Benth. Scroph. Ind. p. 7, ( adnot .) & in DO. Prodr. 10, p. 
323. Kikal Mungo mountain and Solidad ; March and December. A handsome scarlet-flow¬ 
ered species. 
Scrophularia nodosa, Linn.; Benth. in DO. Prodr. 10, p. 309. San Bernardino and Los 
Angeles; March and April. Leaves varying from serrate to deeply lobed, with the lobes 
sharply toothed. 
Diplacus glutinosus, Nutt, in Tayl. Ann. Nat. Hist. 1, p. 138 ; Benth. in DO. Prodr. 10, 
p. 368. D. leptanthus, Nutt. 1. c. San Isabel, &c.; May. A beautiful flowering shrub with 
red or orange yellow flowers. It is variable in the breadth of the leaves as well as in the length 
of the peduncles. 
D. glutinosus var. pubescens: branches and under surface of the leaves pubescent; peduncles 
many times shorter than the calyx. D. longiflorus, Nutt. 1. c.; Benth. 1. c. Between San 
Bernardino and San Diego; April. Peduncles, 2-3 lines long. Calyx, nearly an inch in length. 
The corolla in this variety is pale yellow or, sometimes, almost cream color.

Mimulus brevipes, Benth. Scroph. Lnd. p. 28. & in DO. Prodr. 1. c. San Isabel, and from 
San Luis Rey to San Diego ; May. The specific name is not appropriate, for the peduncles are 
one third of an inch long. This and several other species resemble Diplacus in the placentae 
remaining adnate to the valves of the capsule after dehiscence.
