lower shorter, 3-parted and recurved. The plant is ambiguous between the sections Cepocosmus 
and Elmigera. 
上 ENTSTEMON CORDIFOLIUS, Benth. Scroph. Ind. p. T, adnot & in DC. Prodr. 10, p. 329. 
Mountains east of San Diego, California; June; Parry. Near the town of the same name; 
Мау; Thurber. Santa Barbara; Major O. Rich. This species differs from all the rest of the 
genus in its somewhat climbing habit. It runs over tall bushes like a Lonicera, and has bright 
scarlet flowers, which are resupinate. 
PENTSTEMON TERNATUS, (Torr. MSS.): glaber; caulibus e basi fruticosa erectis ; foliis ternatim 
verticillatis lanceolatis argute denticulatis utrinque acutis; panicula laxa Mailen: corollae 
tubo elongato vix ampliato labio recto; filamento sterili barbato.—Mountains east of San Diego ; 
June; Parry. Branches straight ico slender. Leaves about one inch long. Flowers in 
terminal racemose panicles. Pedicels verticillate. Segments of the calyx ovate-lanceolate, acumi- 
nate. Corolla nearly an inch long, pale scarlet according to Dr. Parry. This species belongs 
to the section Elmigera of Bentham. 
PENTSTEMON CENTRANTHIFOLIUS, Benth. Scroph. Ind. p. Т, adnot. & in DC. Prodr. 10, p. 823, 
Mountains east of San Diego, California; June; Parry. Also near Monterey ; Dr, Andrews 
and Mr. Shelton. А fine deep scarlet-flowered species, with the leaves very variable in breadth. 
PENTSTEMON BREVIFLORUS, Lindl. Bot. Reg. t. 1946; Benth. in DC. Prodr. 10, p. 329, Cali- 
fornia, (near Monterey;) Rev. A. Fitch. A rare and remarkable species; also found by Dr. 
Bigelow on the Stanislaus river. Corolla yellow, except the lobes of the lower lip, which are 
pale purple. 
PPNTSTEMON HETEROPHYLLUS, Lindl. Bot. Reg., t. 1899; Benth. in DC. Prodr. 10, p. 300; 
Gray in Bot. Whipp. Rep. Mountains east of San Diego, California; June; Parry, Near 
Monterey; Dr Andrews. Our specimens appear to be suffrutescent. The flowers are pale 
purple. 
PENTSTEMON ANTIRRHINOIDES, Benth. in DO. Prodr. 10, p. 594. Dry valleys among the moun- 
tains east of San Diego, California; June; Parry. San Pasqual; Thurber; May. А rare 
shrubby species, 3 or 4 feet high. 
LzucoPHYyLLUM TExANUM, Benth. in DC. Prodr. 10, p. 344. Common in southern and western 
Texas, occurring in all the collections. The stigma is bilamellate, as described by Kunze, but 
the two lamellae commonly cohere. This must be a beautiful shrub when loaded, as it often is, 
with its rich violet-purple blossoms, contrasting with its silvery white foliage. In the finest 
specimens the limb of the corolla is fully an iuch in diameter, and delicately soft-bearded within, 
and the wide tube two-thirds of an inch long to the base of the lobes. j Sometimes the fifth 
stamen is present and imperfectly antheriferous. | (ao. 
LEUCOPHYLLUM MINUS (sp. nov.): humile; foliis сола дынан retusis pube minuta 
argenteis ; calycis laciniis linearibus; corolle lobis tubo dimidio brevioribus.—Hills on and 
near the Pecos; Wright, (442, 1481.) Between Van Horn's Wells and Muerta; Bigelow, 
Parry. A low, spreading shrub, only two feet high ; the tomentum much finer and closer than 
in the foregoing, and the purple flowers not half the size. Leaves from a quarter to half an 
inch long, including the petiole or tapering base. I am not sure that this is specifically distinct 
from L. ambiguum, having no specimen of that species. The corolla is, however, as deeply 
cleft as in L. Texanum. |
