210 SAPINDACEAE. 
UNGNADIA. Mexican Buckeye. 
(Family Sapindaceae). 
Tender shrub: deciduous. Twigs 
moderate, subterete: pith moder- 
ate, rounded, continuous, slightly 
brownish. Buds solitary, some- 
what above the axil, sessile, glo- 
bose, very red-hairy and with 
concealed scales, the end-bud 
lacking. Leaf-scars alternate, 
somewhat raised, 3-lobed: bundle- 
traces numerous, following’ the 
contour of the scar, or somewhat 
clustered in 3 groups: stipule- 
sears lacking. , 
Like the horsechestnut and 
true buckeyes, the large seeds of 
this species contain a poisonous 
principle. It is considered worthy 
of cultivation where the winter 
temperature is moderate, but 
rather as a novelty than in com- 
petition with many other shrubs. 
Like the following genus, it has the sapindaceous char- 
acter of alternate leaves, in contrast with the opposite leaves 
of Hippocastanaceae. 
Twigs densely dingy-tomentulose. U. speciosa.
