(874, in part) ; 61 6|- Parry & Palmer. Much resembling C. canes- 

 cens, but with more ovate leaves, and with the fruit and the more 

 unequally inserted stamens of the section £ddya. The embryo is 

 straight and the cotyledons entire. 



COLDENIA TOMENTOSA. Resembling the last, but of closer habit 

 and more densely leafy, the thicker ovate-lanceolate leaves densely 

 tomentose beneath, as well as setosely hispid, more strongly revolute 

 and mostly with shorter petioles : flowers somewhat larger, " purple " 

 or " magenta," with longer filaments and larger anthers : nutlets de- 

 cidedly larger (§ of a line long) and more coarsely granulated. — In 

 the Sierra Madre, south of Saltillo (864). 



CoLDENiA Greggii, Gray. At San Lorenzo de Laguna, Coahuila 

 (865). " Flowers rose-color." 



TouRNEFORTiA CAPiTATA, Mart. «fc Gal. At Guanajuato (Duges) ; 

 613 Parry «fe Palmer. 



TouRNEFORTiA MoKCLOVANA. Perennial, stout, herbaceous, a 

 foot high, tomentosely pubescent throughout : leaves ovate to oblong- 

 lanceolate, acute, abruptly cuneate at base, 2 to 4 inches long, on 

 stout petioles : spikes in pairs or threes, on peduncles nearly equalling 

 the leaves, ebracteolate : calyx-lobes narrowly linear, 1| lines long; 

 corolla glabrous, 3 or 4 lines long, the limb as long as the tube, and 

 throat naked : anthers sessile on the middle of the tube, acute : stigma 

 conical, sessile : fruit subglobose, pubescent, \\ lines in diameter. — 

 In the mountains northeast of Monclova, Coahuila (887), Resem- 

 bling T. hirsutissima, but with more simple inflorescence, glabrous 

 corolla, etc. 



Heliotropium angustifolium, Torr. In the Caracol Mountains 

 (879), at Soledad (880), and Juraz, in Coahuila (881), and at Monte- 

 rey, Nuevo Leon (405, 878). Flowers cream-color. 



Heliotropium confertifolium, Torr. At Laredo, on the Rio 

 Grande (875), the typical form; 616 Parry & Palmer. This is 

 probably the same as H. rupestre, Mart. & Gal., which is an older 

 name. Also a less silky variety, more diffuse and with the leaves less 

 crowded, from Monclova (863) and Soledad, Coahuila (890). This 

 is the H. limbatum of the Botany of the Mexican Boundary, scarcely 

 diflfering from H. limhatum, Benth., but in the more leafy and scarcely 

 at all scorpioid inflorescence. Flowers white. 



Heliotropium inundatum, Swartz. At San Lorenzo de Laguna, 

 Coahuila (882), and a low decumbent form in the San Miguelito 

 Mountains of San Luis Potosi (726 Schaflfner) ; 619 Parry & Palmer. 

 Also a variety, more canescent and with larger and more hispid fruit
