S. tristis, Hortul. 
In Virginia and Carolina. T? . v. v. s.Jl. ; v. s. c.Jl. 
in Heri. Banks, specimen Houstonianum. This spe- 
cies, so frequently found in the gardens under the 
name of S. tristis, is very far from being in any way 
related to it. The specimen in the Banksian Herba- 
rium was collected by Houston, and, as it is said, in 
Vera Cruz. But I am confident it is a more northern 
plant, as I frequently have seen it in Virginia. The 
branches are extremely brittle at their base.
