var. nov. 
Rootstock short and thin, with a number of stout, long, 
fibrous roots. Stem branching freely almost from the base, with 
lanceolate leaves 4-5 cm. long, rather long-petioled; leaves of the 
branches broader, 2 cm. long, and of the numerous secondary 
branches with their almost innumerable verticils ovate, 1 cm. 
long. The plants though collected immediately before the frost, 
showed no signs of flower buds. Perhaps their excessive tendency 
toward leaf production exhausted their ability to complete their 
growth.
