lower shorter^ 3-parted and recurved. The plant is ambiguous between rhe sections Cepocosraus 



and Elmigera. 



Pentstemon cordifoliuSj Bentli, Scroph. Ind. p. Y^ achwt d in DC. Prodr. 10, ^9. 320. 



Mountains oast of San Diego, California; June; Parry. Near the town of tbe same name; 

 May ; Tlnirher. Santa Barbara ; Major 0. Ricli. This species differs from all tbe rest of the 

 genus in its somewhat climbing habit. It runs over tall bushes like a Lonicera, and has bright 

 ecarlet flowers, which are resupinate. 



Pentstemon TERXAius, (Torv. 3ISS.): glaber ; caulibus e basi fruticosa erectis ; foliis ternatini 

 verticillatis lanceolatis argute denticulatia utrinque acutis ; panicula laxa pauciflora ; corolh^ 

 tubo elongato vix ampliato labio recto ; filaraentp sterili barbato. — Mountains east of San Diego ; 

 June; Parry. Branches straight and 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 centrantiiifolius, Benih. Scroph. Ind. p. 7^ adnot. d: in DC. Prodr. 10, p. 323. 

 Mountains east of San Diego, California ; June ; Parry. Also near Monterey ; Dr. Andrews 

 and Mr. Shelton. A fine deep scarlet-flowered species, with the leaves very variable in breadth. 



Pentstemon breviflorus, Lindl. Bot. Reg. t. 1946; Benth. in DG, Prodr. 10, p. 329. Cali- 

 fornia, (near Monterey;) Bev. A, Fitch. A rare and remarlcable species; also found by Dr. 

 Bigelow on the Stanislaus river. Corolla yellow, except the lobes of the lower lip, which are 



pale purple. 



Pentstemon 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. Xear 



■Monterey ; Dr Andretas. Our specimens appear to be suff^rutescent. The flowers are pale 

 purple. 



Pentstemon ANTiRRmNOiDES, Benth. in DO. Prodr. 10,^. 594. Dry valleys among the moun- 

 tains east of San Diego, California ; June ; Parry. San Pasqual ; Thurher; May. A rare 

 shrubby species, 3 or 4 feet high. 



Leucophyllum Texanum, Benth. inDG. Prodr. 10,^. 344. Common in southern and western 

 TexaSj occurring in all the collections. The stigma is bilamellate, as described by KunzCy but 

 the two lamellae commonly cohere. This must be a beautiful shrub when loaded, as it often is, 

 witb its rich violet-purple blossoms, contrasting with its silvery white foliage. In the finest 

 specimens the limb of the corolla is fully an inch in diameter, and delicately soft-bearded within, 

 and the wide tube two-thirds of an inch long to the base of the lobes. Sometimes the fifth 

 stamen is present and imperfectly antheriferous. 



Leucopuyllum minus (sp. nov.) : humile ; foliis obovato-spathulatis retusis pube minuta 

 argenteis ; calycis laciniis linearibus ; corolL'B 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 &ize. Leaves from a quarter to half an 

 incli long, including the petiole or tapering base. I am not sure that this is specifically distinct 

 from L. arabiguum, having no specimen of that species. The corolla is, however, as deeply 

 cleft as in L. Texanum. 



MiMULus LUTEUS, L. ; Benth. in DG. Prodr. 10, p. 370 ; var. gracilis ; floribus minoribus. (Near 

 M. Scouleri ; Hooh ; which can be only a form of M. luteus.) Copper Mines^ New Mexico and
