ViOLACEAE 



Calceolaria appendiculata 



The slender elongate spreading branclilets shortly and 

 roughly hairy, the leaves scabrellate. Leaves opposite, the very 

 short petioles margined, about as broad as long, the blades 4 to 

 7 cm. long, 2 to 3 cm. wide, ovate with blunt or rounded base and 

 acuminate and acute smnmit, obscurely crenate-dentate, thin, 

 rigid, l)right-green, the slender venation lightly prominent on 

 both sides, the secondaries 5 or 6 on each side, strongly falcate 

 and obscurely connecting near the margin, the venation loosely 

 reticulate. Stipules very small, subulate, thickish, deciduous. 

 Flowers irregularly clustered in axils, snbracemose, the 

 slender pedicels at length 5 nnu. long, bearing 2 subopposite 

 minute subulate braetlets below the middle. Calyx 1.5 mm. 

 broad and nearly as long, 2 sepals slightly smaller. Large petal 

 nearly thrice the length of the calyx, its yellowish limb about 

 half the length and two thirds of the breadth of its white claw, 

 with which it is connected by a narrow base ; ovate, obtuse, entire, 

 the claw ovate, apparently without either sac or glands. Lateral 

 petals nearly as long as the large one, inequilaterally ovate, ob- 

 tuse, about as broad as the claw of the large one. Fourth and 

 fifth petals a little shorter than the lateral, the basal portion 

 narrowly ovate, the upper portion about as long, linear, obtuse, 

 connected by a narrow base. Two anthers connate, their ap- 

 pendages about half as long as the other three. 



Species peculiar in the apparent appendaging of the two 

 petals, of which the lower portions are probably to be regarded 

 as claws. 



Huachi, 1,800 feet, 0. E. White, September 4, 1921 {no. 1009). 



Calceolaria biacuminata 



Glabrous, the branclilets elongate, slender, widely spreading. 

 Stipules inconspicuous, subulate. Leaves opposite, the petioles 

 1 mm. long, very slender, the blades 1.5 to 4 cm. long, 5 mm. to
