318 PROCEEDINGS OF THE AMERICAN ACADEMY 



15 lines long, the petals spatulate, about 9 lines long, the claw open- 

 ing by a narrow orifice into the very slender elongated sjjur, which is 

 4 inches long or more. — In the Caracol Mountains, south of Mon- 

 clova, Coahuila (10). Allied to A. ccerulea and A. chrysantha, but 

 distinguished from both by the narrower petals and the constricted 

 mouth of the much more elongated spur. 



Delphinium leptophtllum, Hemsl. In the San Miguelito 

 Mountains (27 SchafFner) ; Guanajuato (Duges) ; 7 Parry & Palmer. 



Delphinium azureum, Michx. Guajuco, Nuevo Leon (11). 

 Apparently not differing from slender few-flowered forms of this vari- 

 able species. 



CoccuLus Carolinus, DC. San Antonio, Texas (12), 



CoccuLus DiVERsiFOLius, DC. ( C. oUongifolius, DC.) Laredo, 

 on the Rio Grande, Texas (13). Both with oblong and with ovate- 

 cordate leaves, representing the two forms figured by Mo9ino & Sesse 

 and described by De Candolle. 



Berberis Schiedeana, Schlecht. (^Mahonia trifolia, Cham. & 

 Schlecht.) In the Sierra Madre, forty miles south of Saltillo (14). 

 The specimens accord very closely with Schlechtendal's description, 

 except that the leaves are all trifoliolate, as in Schiede's original 

 specimens. The racemes are short, about equalling the petioles. 

 The Mahonia ilicina of Schlechtendal (Berberis, Hemsl.), at first 

 supposed by him to be this species, he afterward identified (Bot. Zeit. 

 12. 655) Avith B. pallida, Hartw. 



Berberis trifoliolata, Moric. In the same locality (15), and 

 also at Lerios, forty-five miles east of Saltillo (16). 



Berberis gracilis, Hartw., var. With the 5 to 7 leaflets often 

 rounded at base and the racemes shorter (1 or 2 inches long). In the 

 San Miguelito Mountains (711 Schaffner) ; 8 Parry & Palmer. 



Ntmph^a ampla, DC. At San Lorenzo de Laguna, Coahuila 

 (17), and at Monclova (18). 



Argemone platyceras, Link & Otto, Icon. PI. Ear. Hort. 

 Berol. i. 85, t. 43. {A. hispida, Gray.) At Saltillo (19) ; 10 Parry 

 & Palmer. A probable variety was also collected at Parras (20), 

 with the large flowers of a decided pink color, and the seeds less than 

 a line long, scarcely more than half of the usual size. 



Argemone fruticosa, Thurber. At San Lorenzo de Laguna, 

 Coahuila, in flower and fruit (21). The flowers, which have not 

 before been collected, are noted as sulphur-yellow, and are 2.V to 3 

 inches in diameter. The beaks of the sepals are large and conical, 

 terminating in stout rigid spines.
