Trailing arbutus (Epigaea repens) January, 1919. 



Yellow jessamine (Jasminum nudiflorum) 1 January, 1876; January 1, 

 1919. 



In addition to the above plants, the Golden Bells (Forsythia spp.), it is 

 believed, sometimes bloom in the true winter months, although no definite 

 date of their so doing is now at hand. 



During the winter of 1918-1919, various herbaceous plants as Senecio, 

 Capnoides, Arabis, Galium, and Veronica seemed more fully grown than 

 usual. Elder (Sambucus canadensis) and certain cultivated roses had put 

 out leaves up to an inch in length in February. 



Casual Flowering. 



In an entirely separate category should be placed two irrepressibles 

 which bloom at the slightest encouragement. These are the chickweed 

 (Stellaria media) and the dandelion (Taraxacum officinale). Sample dates 

 of winter flowering of the former are: December 6, 18, 25, 30; January 5; 

 February 19, 20; and for the latter: November 16; December 1, 8, 23, 25, 

 first week of January and February 2. Two of the other plants previously 

 mentioned seem bent on entering this class, namely hepatica and pepper- 

 grass. The moss pink (Phlox subulata) 1 , according to Dr. E. T. Wherry, 

 has been in bloom in every month during the winter of 1918-1919. 



In the writer's former home — Indiana — one of the common blue or 

 johnny violets bloomed at almost any season; here the only violet that 

 manifests such a tendency — and that to a much lesser degree — is the birds- 

 foot violet.
