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- 

 scars 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.
