The glabrousncss of the calyx and the upper part of the inflorescence 

 suggests A. melanocarpay but the leaves are pubescent beneath and the 

 fruit is bright red and ripens In October. Specimens with similar pubescence 



1 have seen from Maine, Virginia and South Carolina, but in llie absence 

 of fruits it is impossible to say if they belong here or to A . florihiinda , This 

 new variety is apparently not identical with A. arbutifolia b. glabra El- 

 liott (Sketch Bot. i. 557 [1821]) which is described as having a glabrous 

 calyx and the leaves a little hairy beneath while young, and glabrous at ma- 

 turity, while in our form the leaves are tomentose beneath as in the type.^

This is a dwarf form with creeping and rooting stems, small leaves and 

 dark red fruits. I have little doubt that Lindley's Pyrus depressa is the 

 same. Its dark purple fruits are described as downy, as are those of 

 Mespihis pumila, which excludes A. floribunda with glabrous lustrous 

 fruit. Specimens from Newfoundland agree in habit with the plant 

 figured by Schmidt, but the color of the mature fruit of the Newfoundland 

 plant is not known.

* There was no specimen of this variety to be found in the Elliott herbarium preserved in 

 the Charleston Museum, Charlesto:^, S. C., but in the local herbarium I noticed a specimen 

 from the Chicora woods, collected March 28, 1913, which answered Ell'ott's description and 

 was stated to have ''red berries."
