LARDIZABALACEAE. 53 
DECAISNEA. 
(Family Lardizabalaceae). 
Loosely branched large gla- 
brous shrubs: deciduous. Twigs 
coarse, terete: pith large, homo- 
geneous, roundish, pale. Buds 
solitary, sessile, large, ovoid-acu- 
minate, suberect or appressed, ob- 
tusely somewhat 2-edged, with 2 
scales, the end-bud lacking. Leaf- 
scars alternate, low, shield-shaped, 
very large, with 7-9 bundle-traces: 
stipule-scars lacking. 
Decaisnea and the two follow- 
ing genera, with four others, are 
now admitted to constitute a nat- 
ural family, named after the ge- 
nus Lardizabala. The affinities of 
the plants are such, however, that 
those now placed in the Lardiza- 
balaceae have found earlier clas- 
sification in the related families 
Berberidaceae and Menisperma- 
ceae. 
Twigs buff: buds glaucous, coarsely wrinkled. D. Fargesii.
