the middle, but with firmer walls ; the seeds are less turgid and more 

 shining. 



Ceanothus azureus, Desf. (C. cceruleus, Lag.) Locality un- 

 certain (17G) ; 118 and 119 Parry & Palmer. 



Ceanothus depuessus, Beuth. San Rafael Mountains (103 

 SchafFner) ; 122 Parry & Palmer, referred to G. huxifoUus. 



Ceanothus Gueggii, Gray. A variety with the leaves white- 

 toraentose beneath, and occasionally with a few spinose teeth. At 

 Lerios, Coahuiia (175). Also the typical form from the Morales 

 Mountains (102 Schaffuer) ; 120 Parry & Palmer. 



Ampelopsis pubescens, Schlecht. At Guanajuato (Duges). 



ViTis INCISA, Nutt. At Laredo, on the Rio Grande (177). 



ViTis ^STivALis, Michx. At Parras, Coahuiia (180), and in the 

 mountains near Saltillo (2126). — Also var. cinerea, Engelm. (?), 

 with different seeds from those of the jjreceding. Southwestern 

 Texas (178). 



ViTis CORDIFOLIA, Michx., var. (?) Covered throughout with a 

 very short spreading pubescence, the leaves less acuminate and more 

 bluntly toothed than in the typical form. In the Caracol Mountains, 

 southeast of Monclova, Coahuiia (179). 



Cakdiospermum Halicacabum, Linn. At Uvalde (185) and at 

 Sutherland Springs, Texas (3G6). 



Cardiospermum molle, Linn. At San Luis Potosi (100 Schaff- 

 ner) ; 123 Parry &, Palmer. 



Serjania (?) INFLATA. Branches herbaceous, elongated, puberu- 

 lent, the tendrils often not floriferous : leaves like those of Cardio- 

 spermum Halicacabum, somewhat pubescent : flowers in a small racemose 

 panicle, bicirrhose at base : petals 3 lines long : ovary about equalling 

 the pubescent style ; capsule an inch long or more, glabrous, thin-mem- 

 branous, resembling that of C. Halicacabum, but abruptly rounded 

 above, and the carpels attenuate downward and wing-margined below 

 the middle : seed solitary in each cell, attached to the middle of the 

 axis. — In the Caracol Mountains, Coahuiia (186). Closely allied 

 to 8. macrococca^ Eadlk,, and S. incisa, Torr. (^Paullinia subulata, 

 Gray), and intermediate between Serjania and Cardiospermum. It 

 would perhaps be better to refer all these species to the latter genus. 



Serjania brachycarpa. Gray. At Corpus Christi Bay (125). 



Serjania racemosa, Schum. At Guanajuato (Duges). 



Ungnadia speciosa, Endl. At Saltillo, Coahuiia (187), and at 

 Guajuco, Nuevo Leon. 



Sapindus marginatus, Willd. In Burnet County, Texas (184).
