This is a charming new Pentstemon, very distinct from any 
hitherto known to us, and which will prove a great acquisition 
to our gardens. It was discovered by Dr. Wright in Texas, and 
has been distributed among the very interesting dried collections 
of that gentleman, without any name, by Dr. Engelmann, who, 
we trust, wil] not object to its bearing the name of its discoverer. 
It flowers in June and July.

foot and a half or two feet high, terete, branching from the base,

oblong or obovate, entire, tapering into a stalk, all except the 
uppermost pair at the base of the panicle, which are ovate,

long, bearing several pairs of small ovate bracteas, from the axil 
of each of which is seen a 2-flowered peduncle, with a small ovate
