254 SCROPHULARIACE.E. Antirrhinum. 



A. filipes, Gray, 1. c. More delicate than the preceding, and with broader more mem- 

 branaceous leaves: capillary tortile peduncles equally long : flowers very small, "white." 

 Ives Colorad. Exped. Bot. 19. Arizona, in desert arroyos of the Colorado, Newberry. 

 Flowers perhaps imperfect, the corolla little exceeding the calyx. Perhaps a depauperate 

 or attenuated state of the foregoing. 



* * Perennial, climbing by the slender tortile petioles and axillary peduncles : calyx longer than 

 the globular capsule. 



A. maurandioid.es, Gray, 1. c. Low or tall climbing : leaves triangular-hastate or the 

 lower cordate-hastate; the lateral lobes often with a posterior tooth: corolla purple or 

 sometimes white (half to an inch long), with a nearly closing palate: sepals lanceolate, 

 very acute : style slender : seeds strongly costate, the ribs corky. Usteria antirrhlniflora, 

 Poir. Maurandia aittirrhittiflura, Willd. Hort. Berol. t. 83; Bot. Mag. t. 1043; Benth. I.e. 

 M. personuta, Lagasca. Texas to Arizona and the borders of California. Common in 

 cultivation. (Mex.) 



5. GAMBELIA, Gray, 1. c. Capsule and seeds of preceding section : stems 

 erect and more or less shrubby, not climbing : palate of the tubular corolla some- 

 what prominent, but not closing the throat : most of the leaves opposite or in 

 threes.-- Gambelia, Nutt. PI. Gamb. 149. 



A. speciosum, Gray, 1. c. Shrub, 3 or 4 feet high, somewhat pubescent, leafy through- 

 out : leaves oval or oblong, short-petioled, coriaceous : corolla " scarlet " or pink-red, 

 hardly an inch long, thrice the length the lanceolate sepals, and the tube thrice the length 

 of the narrow lips. Gambelia speciosa, Nutt. 1. c. t. 22. California, on the Island of 

 Catalina, Gambell. (Guadalupe Island, Lower Calif., Palmer.) 



A. junceum, Gray, 1. c. Shrubby slender stems glabrous, 2 feet high : leaves small, 

 oblong-linear, or above hardly any : tube of the corolla 8 to 12 lines long. M. juncea, 

 Benth. Sulph. 41. From San Diego southward (to the bay of Magdalena in Lower Cali- 

 fornia, Hinds; also Cerros Island, Dr. Streets). 



5. MAURANDIA, Ortega. (Dr. Maurandy, a botanical teacher at Car- 

 thagena.) -- Perennial herbs (Mexican and Arizonian), climbing by the slender 

 tortile petioles and sometimes by the axillary peduncles ; the leaves cordate- 

 triangular or hastate, only the lower opposite ; and showy purple or rose-colored 

 or rarely white flowers. Gray, Proc. Am. Acad. vii. 377. Maurandia (excl. 

 1) and Lophuspermum (Don), Benth. in DC. Prodr. I.e. This comprises the 

 two true Maurandias with wingless tuberculate seeds, Lbphospermum, of one or 

 perhaps two species, with seeds bordered by an irregular and lacerate wing ; and 

 the section EPIXIPHIUM, Engelm., with a narrow entire wing to the seeds, and 

 capsule pointed by the subulate indurated style, containing the following 

 species. 



M. Wislizeni, Engelm. Glabrous, mostly low-climbing : leaves hastate, or some of 

 them sagittate ; the lowest obtuse, the others acuminate and with pointed basal lobes : 

 peduncles short: corolla (pale blue, an inch long) with lips about half the length of the 

 rather ample tube : sepals in flower linear-lanceolate, becoming in fruit triangular-lanceo- 

 late and gradually acuminate, much enlarged, rather rigid, very veiny-reticulated, and 

 strongly saccate-carinate at base, enclosing the coriaceous globose-ovate capsule, and 

 about the length of the sword-shaped indurated style : seeds compressed, oval, surrounded 

 by a narrow entire wing, the sides chaffy-rugose. Gray in Bot. Mex. Bound. 111. New 

 Mexico, on the banks of the Rio Grande, &c., and adjacent borders of Mexico, Wislizenus, 

 Parry, Wright, Biyelow. 



6. MOHAVEA, Gray. (Name of the river on the banks of which the 

 plant was discovered by Fremont. It had been previously collected, in fruit 

 only, by Dr. Coulter.) Single species.
