SYMPLOCACEAE. 307 
SympLocos. Sweet Leaf. 
(Family Symplocaceae). 
Shrub or small tree: tardily de- 
ciduous. Twigs moderate, terete: 
pith moderate, pale, chambered. 
Buds sessile, solitary or super- 
posed, broadly conical, with about 
4 seales. Leaf-scars alternate, 
half-round, low, bundle-trace a 
single crescent-shaped or trans- 
verse aggregate: stipule-scars lack- 
ing. Leaves when present oblan- 
ceolate, cuneately petioled, entire. 
(Hopea). 
The chambered pith of Symplo- 
cos, which seems to have escaped 
the notice of special writers on . 
the pith of trees, is mentioned 
and photographically illustrated 
in Hough’s Handbook of the 
Trees of the Northern States and 
Canada, p. 381. The tree is ever- 
green in the southern part of its 
range, and holds its foliage until heavy frosts come else- 
where. It is sometimes called horse sugar because its sweet- 
ish leaves are eaten by stock after green herbage has gener- 
erally disappeared in early winter. 
End-bud absent: leaf-scars 2-ranked. S. paniculata. 
End-bud present: leaf-scars more than 2-ranked. 
(1). S. tinctoria.
