subcuneate at base upon a sbort slender petiole, 2 to 10 lines loi^ : 

 pedicels very slender, 2 to 4 (or in fruit 6 to 8) lines long: p< 

 linear, equalling the filaments: fruit depressed-globose, 2 or 3 lines 

 broad. — Ravines about Guaymas. (200.) 



Serjania (Phacococcus) Palmkri. A stout climber, pubes-

 2 lines or more broad, faintly reticulate, thin and crustaceous, narrowly 

 crested on the back, the wing broadly dilated to a rounded base (3 or 

 4 lines broad) ; dissepimeut narrow : seed attached below the middle,
