3. M S C U L U S, Linn. 

 1. iEsCULUS Californica, Nutt. 



Hab. Fertile places along the Sacramento, and near San Fran- 

 cisco. — Although this is commonly a shrub, only 5 to 10 feet high, 

 Dr. Pickering found individuals of it 25 feet high, with a trunk a 

 foot in diameter. It produces large straggling branches from near 

 the base. On vigorous shoots the leaflets are six to eight inches long 

 and nearly four inches wide. 



Ord. 22. CELASTRACEJE. 



1. PACHYSTIMA, Baf. (Oreophila, Nutt.) 



1. Pachystima Mtrsinites, Raf. 



Hab. On the Cascade Mountains, and other parts of Washington 

 and Oregon Territories. — Leaves variable in size and form, as well 

 as in the size of the serratures. It is remarkable that all the speci- 

 mens of this plant that we have received in numerous collections, are 

 in flower only. No botanist except Nuttall appears to have examined 

 the fruit.
