<-lifferent constitutions ; and some are incapable of being poisoned with it at all. Persons of irritable habits 
are most liable to receive it. 
Rhus aromatica and suaveolens, the male and female of one species, have been made into a distinct genus 
called Sckmaltzia, by Desvaux and Turpinia, and afterwards Lobadium, by the ingenious M. Rafinesque 
Schmaltz. The expressed oil of the seed of this species, and also of R. succedanea, acquires the consistence 
of suet and serves for making candles. 
R. Toxicodendron is poisonous to some persons, like R. vernix, but in a less degree. Kalm relates, that of 
two sisters, one could manage the tree without being affected by its venom, whilst the other felt its exhalations 
as soon as she came within a yard of it, or even, when she stood to windward of it, at a greater distance ; that it 
had not the least effect upon him, though he had made many experiments upon himself, and once the juice 
squirted into his eye ; but that on another person\5 hand, which he had covered very thick with it, the skin, 
a few hours after, became as a piece of tanned leather, and peeled oflF afterwards in scales. 
R. pumila is another dangerous species. Lyons, the collector, suffered severely for several weeks, after only 
collecting the seeds. 
R. cotinus is cultivated for tanning leather near Valcimara in the Apennines, where it is called Scotino. 
682. Cassine. An American name. These are shrubs with handsome foliage, but generally inconspicuous 
white or green flowers. C. Maurocenia has its specific name in honor of the Venetian senator F. Mauroceni, 
who had a fine garden at Padua. 
683. Spathelia. The upright habit and want of bra ches make this tree resemble a palm-tree, anciently 
called 2t«3^-/i. A very handsome stove shrub, rarely flowering.
