BOTANY. 111 
MAURANDIA (Еріхірнгм) WISLIZENI (sp. nov. Zngelm.): scandens, glabra; foliis hastatis ; 
pedicellis axillaribus petiolo sæpiusque calyce brevioribus; corolla “pallide сюгша,” fauce 
pervia nuda; calyce fructifero demum subcoriaceo valde aucto et reticulato basi 5-angulato seu 
5-carinato, lobis triangulari-lanceolatis sensim acuminatis; capsula ovoidea coriacea calyce in- 
clusa stylo ensiformi rigido persistente cornuta, loculis juxta apicem rima transversali dehiscen- 
tibus ; seminibus compressis ovalibus alatis disco paleaceo-rugosis.—Along the Rio Grande below 
Doña Ana, etc. This was first received in the collection of Dr. Wislizenus, and afterwards in that 
of Wright and most others from the northern borders of Mexico. Dr. Engelmann proposed it 
long ago, in MSS., as a new genus, under the name of Epiziphium maurandioides, which is here, 
with his permission, changed to Wislizeni, since I incline to view the plant as thetype of a mere 
subgenus of Maurandia, freely admitting, however, that its characters are as well marked as 
those of Lophospermum. ‘lhe remarkable fructiferous calyx is 8 or 9 lines broad at the base, 
strongly 5-angled and keeled, and an inch or an inch and a half long; the sword-shaped per- 
sistent style nearly equals the calyx-lobes, and the dehiscence is by a clean transverse chink on 
each side, which inclines to extend downwards so as to become valvular. Seeds blackish, dis- 
tinctly winged, 14 to 2 lines long. 
ANTIRRHINUM NUTTALLIANUM, Benth. in DO. Prodr. 10, p. 592. San Diego, California ; 
May-June ; Parry. Оп the Great Colorado; Schott. Leaves of the branches mostly roundish- 
cordate. Segments of the calyx ovate, a little unequal. Persistent base of the style oblique. 
ANTIRRHINUM CouLTERIANUM, Benth. l. c. Near San Pasqual, California, May; Thurber. 
Mountains east of San Diego, June; Parry. Root annual. Stem 3 or 4 feet high, supporting 
itself on other plants by its twining slender branches. Raceme nearly a foot long: persistent 
base of the style oblique. This species is near A. majus. 
LINARIA CANADENSIS, Dum.; Benth. in DO. Prodr. 10, p. 278. Near the Copper Mines, and on 
Rock creek, New Mexico ; Bigelow. Monterey, California; Parry. Upper Sacramento ; Stillman. 
SCROPHULARIA COCCINEA (sp. nov.): glabra ; foliis deltoideo-ovatis vel subcordatis acutis grosse 
dentatis, dentibus pauci-serratis ; thyrso oblongo aphyllo ; cymis plurifloris floribusque minutim 
glandulosis ; calycis segmentis ovatis margine haud scuriosis ; corolla lete coccinea, lobis 2 pos- 
ticis tubo ovato-oblongo gibboso dimidio breviore, anticis brevissimis ; anthera sterili obovato.— 
At the base of a rocky ledge near the summit of a mountain, Santa Rita del Cobre, New Mexico ; 
Wright (1410), Bigelow. What appears to be the same species in fruit was collected by Dr. 
Bigelow near the Organ mountains. А truly handsome species. Specimens raised from seeds 
in the autumn of 1852 (but which were unfortunately soon lost) displayed flowers as bright red 
as those of Stachys coccinea. 
COLLINSIA BICOLOR, Benth. im Hort. Trans. n. ser. 1, p. 48, & in DC. Prodr. 10, p. 318. 
Oak woods near Santa Barbara, and San Diego, California; March ; Parry. 
PENTSTEMON AMBIGUUS, Torr. in Ann. Lyc. N. Y. p. 228, & in Marcy's Rep. p. 293, 6. 16. Grav- 
elly hill sides near Tascate; July ; and Burro mountains; September; also near San Diego; 
Bigelow. Sand hills, Chihuahua ; Thurber (142.) A common species in or near the southern 
Rocky mountains. In the figure cited above, the sterile filament is represented as bearing a 
small anther, to which no allusion is made in the letter-press. It is not found in the present 
specimens, but exists in all those collected by Captain Marcy. In this as in several species of 
the genus, either ай four fertile stamens or the two posterior are often free from the corolla 
nearly or even quite to the base. РРА /%/
