llection of Dr. Wislizenus, and afterwards in that 

 borders of Mexico. Dr. Engelmann proposed it 



MSS., as a new genus, under the name of ^ 



with his permission^ changed to Wislizeni, since I incline to view the plant as the type of a mere 

 subgenus of Maurandia; freely admitting, however, that its characters are as well marked as 

 those of Lophospermum. The 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, 1^ to 2 lines long. 



Antikrhinum Nuttallianum, Benth. in DG. Frodr. 10, p. 592. San Diego, California; 

 May-June ; Parry. On the Great Colorado ; Scliott. 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 ; Thiirber, 

 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.

 At the base of a rocky ledge near the summit of a mountain, Santa Rita del Cobre, New Mexico ; 

 Wright (1470), Bigelow. What appears to be the same species in fruit was collected by Dr. 

 Bigelow near the Organ mountains. A 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.

(742,) 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 all four fertile stamens or the two posterior are often free from the corolla 

 nearly or even quite to the base.
