other genera of Cactacese, in which they are sessile and solitary. 

 The petals are pale yellow or tinged vvdth pink, the stamens j^ellow, 

 and the 5-rayed stigina white. The bracted apple-shaped fruit, as 

 I have already stated, is 

 used in the West Indies for 

 tarts and sauces, like goose- 

 berries. Pereskia tampi- 

 cana, a species closely 

 allied to Peresh'm grandi- 

 folia of Brazil, is a Mexi- 

 can species, which has 

 only been collected on the 

 banks of the Hio Panuco, 

 not far from Tampico, in 

 the northern comer of 

 Veracruz. Another species 

 growing at Salinas Bay, 

 on the west coast of Costa 

 Rica, Pereskia hjclinidifora^ attains the size of a small tree, and has 

 yellowish-red flowers with petals fringed along the margin as in the 

 genus Lychnis. Other arboreous species occur in tropical America. 

 One of them, with long slender spines and the habit of an Osage 



orange, was observed 

 by the writer in 189G 

 growing in hedges at 

 Punta Arenas, Costa 

 Rica, where it was 

 called puipute, or ma- 

 teare. It has since been 

 described by Weber as 

 Pereskia nicoyana. As- 

 sociated with it was a 

 columnar organo {Ce- 

 reus aragon'i Weber) 

 with edible fruit locally 

 known as tunas de 

 organo. Pereskia au- 

 tumnalis (plate 10, fig. 

 1), called manzanote in 

 Guatemala, was col- 

 lected by O. F. Cook, of 

 the United States Department of Agriculture, in 1902, at El Rancho, 

 near Zacapa, Guatemala. Excellent photographs of this species 

 by Guy N. Collins have recently been published by Rose, in Contri- 

 butions from the National Herbarium, volume 12, pages 399, plates 52,
