Garden and Forest, 1893, and other species are recorded. 1 

 Ascherson and Magnus 2 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. 



1 : special reason for this difference in color can be assigned. 

 The white forms are found growing (usually in colonies) b) r 

 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. Myrtttlus var. leucocarpon. But in 1879 Schroeter 

 showed that the white color w 7 as due to a fungus which he called 

 Peziza baccarum (now Sclerotinia baccarum). 5 Ten years 

 later Woronin gave a full account of similar white berries found 

 by him in Finland on Vitis-Idaa, Oxycoccus and uligiiwsum, — 

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

 of the fungus producing the color.- 



BOTANICAL NOTES. 



Vaccinium (Origin of the name obscure) ; Vaccimacece. 

 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 te rmina l 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
