ROSACEAE. 113 
Kerria. ‘“Corchorus.” 
(Family Rosaceae). 
Small shrubs: deciduous. Twigs 
somewhat 5-angled or _ ridged, 
very slender, zig-zag: pith rel- 
atively large, white, continuous. 
Buds solitary, sessile, oblong, 
with about 5 exposed scales. Leaf- 
scars alternate, 2-ranked, crescent- 
shaped or 3 sided, somewhat 
raised, small: bundle-traces 3: 
stipule-scars lacking. 
Like Philadelphus, Kerria il- 
lustrates the tenacity of Latinized 
plant names when once estab- 
lished as vernacular names. In- 
troduced as a Corchorus — the 
genus to which the jute plant be- 
longs, the plant still finds cor- 
chorus clinging to it as its garden 
name; just as syringa stands for 
the mock orange and not for the 
lilac, which belongs to the genus 
Syringa, in popular parlance. 
Few people have difficulty in recognizing it at sight, after 
having made its acquaintance once, for its very slender zig- 
zag angled bright green twigs are unlike those of anything 
else that is likely to be seen. Its winter-characters are given 
by Schneider, f. 137; and Shirasawa, 254. 
Twigs green, glabrous: buds subappressed. K. japonica.
