Predominant caulines however in strong vigorous plants are 
triangular-ovate-acuminate with winged base, already mentioned 
as typical; 4 x 214 or less. 
Axiles oblong-lanceolate, incurved into a sessile or a short- 
wing base, often developing a peculiar subcircular dilated wing, 
separated from leaf and stem by an abrupt contraction.  Axiles 
remain large, 375 x 2 in. or less. 
Rameals similar, smaller from the first, 134 x 34 in., persis- 
tently the same in size, sometimes 8 or 9 such on each of a dozen

long ascending branches, the upper ones sessile by a broad base. 
Ramulars at once smaller, triangular-elongate with a broad 
sessile base, resembling the upper axiles of A. Claytoni ; or many 
of them ovate ; a half-inch long or less, and subentire. 
Teeth sharp, dentate or repand on lowest leaves, the points 
becoming more and more forward-directed and acuminated as the 
leaves ascend, the principal axiles and rameals being slit-serrate. 
Little curvature appears, but a few curvescent teeth occur on 
middle caulines. z
