Tedcrium Canadense, Linn. At Saltillo, Coaliuila (1099). 



Teuckiu.-m Cubensk, Linn. At San Lorenzo de Laguna, Coahuila 

 (1101), at Monterey, Nuevo Leon (1100), and in the San Miguelito 

 Mountains (687 Schaffner) ; 727 Parry & Palmer. 1101 is referred 

 by Ilemsley to T. laciniatum^ Torr., which is not clearly distinguished 

 from this species, but is perhaps best defined by the decidedly peren- 

 nial root, much larger flowers, and more elongated calyx-teeth. 



Plantago major, Linn. At Parras, Coahuila (1105), and a very 

 paniculately branched form (1106). 



Plantago Patagonica, Jacq. Between the Frio and Nueces 

 Rivers, Texas (1110), and at San Luis Potosi (659 SchafFuer, in 

 part). 



Plantago Mexicana, Link. A reduced depressed form, with the 

 scapes shorter than the leaves. At San Luis Potosi (65',) Schaffner, 

 in part) ; 765 Parry & Palmer, at least in part. Perhaps the species 

 should be included among the forms of P. Patagonica. 



Plantago Virginica, Linn., var. (?) (Var. longifoUa, Gray, 

 Syn. Flora, 2. 392, in part.) Scapes procumbent, very short : leaves 

 pinnatifid-toothed : capsule exceeding the sepals : seeds red, over a line 

 long, and broader in proportion than in P. Virginica. — Between the 

 Frio and Nueces Rivers, Texas (1108), at San Lorenzo de Laguna, 

 Coahuila (1109), at Monterey, Nuevo Leon (1107), at San Luis 

 Potosi (656 Schaffner) and iu the San Miguelito Mountains (655 

 Schaffner). Collected also by Dr. Gregg at Buena Vista, and by 

 Berlandier at Matamoros (2128), together with a more erect form. 

 763 Parry & Palmer is referred to this species. In the ordinary 

 forms of the species the shorter sepals about equal the capsule and the 

 brown seed is less than a line long. 



Plantago hirtella, HBK., var. (?) Leaves narrowly lanceo- 

 late, attenuate into a long winged petiole, rather sparingly pubescent, 

 entire or obscurely toothed : sepals glabrate, or somewhat pubescent 

 on the midvein, shorter than the capsule : seeds olive-colored. — ■ At 

 San Luis Potosi (657 Schaffner). 400 Bourgeau and 926 Coulter 

 (referred to P. Virginica), 1128 Bourgeau, and 174 Botteri appear 

 to be the same. 



Plantago caulescens. Caulescent, probably perennial, the cau- 

 dex usually branching and the leafy stems 1 to 4 inches long : leaves 

 linear, attenuate each way, silky-pubescent, 2 to 6 inches long by 1 or 



2 lines wide : peduncles exceeding the leaves, erect : spikes capitate, 



3 to lines long: bracts ovate, acutish, shorter than the calyx, the 

 margins scarious below : sepals 2 lines long, nearly uniform, but the
