Garden and Forest, 1893, and other species are recorded.^ 

 Ascherson and Magnus^ have made a special study of the color 

 and form variations of Vaccinium, and citations are given which 

 show the very general distribution of albino forms throughout 

 the world. 



No special reason for this difference in color can be assigned. 

 The white forms are found growing (usually in colonies) by 

 the side of the normal type. If exposed to full sunlight, the 

 fruit is very likely to have a blush cheek, or even to be of a 

 scarlet color. 



The albino forms must, however, be carefully distinguished 

 from the "white berries" caused by the presence of a fungous 

 growth. One of these white forms was described in 1859 by 

 Doll as V. Myrtillus var. leucocarpon. But in 1879 Schroeter 

 showed that the white color was due to a fungus which he called 

 Peziza baccarum (now Sclerotinia baccamm).^ Ten years 

 later Woronin gave a full account of similar white berries found 

 by him in Finland on Vitis-Idcea, Oxycoccus and uliginosum, — 

 three species which are also common in the United States — and 

 of the fungus producing the color.* 



BOTANICAI, NOTES. 



Vaccinium (Origin of the name obscure) ; Vacciniacece. 

 Branching shrubs, creeping vines or small trees (sometimes 

 epiphytes), with alternate, often coriaceous, evergreen or decid- 

 uous, sometimes membranaceous leaves,; flowers small, white, 

 pinkish or reddish in lateral racemes or terminal clusters, some- 

 times solitary in the axils, mostly nodding on slender bracted 

 pedicels and bearing blue black or red berry-like fruits, mostly 

 edible. Calyx 4-5 toothed, adherent to the ovary, persistent, 

 forming a crown-like appendage to the fruit. Corolla various 

 in shape, usually campanulate, cylindraceous or urn-shaped, 

 rarely sub-globose, 4-5 toothed or cleft. Stamens distinct, 

 included within the corolla tube or exserted; anthers often 

 2-awned at the back, the cells separate and prolonged upward
