halves remain closed, and assume a saccate form. In 
reference to this character I find that the neglect of it in 
the drawing of P. speciosus, Dougl. (P. glaber, Pursh) in 
the Botanical Register, renders it impossible to distinguish 
that figure from P. azureus. The anthers of P. speciosus 
have divaricated cells, as may be seen in Douglas’s type 
specimens at Kew, whilst those represented in the Register 
are of exactly the same form as in azureus. 
Pentstemon azwreus was raised from seeds sent to the 
Royal Gardens in 1895 by Professor Goodale, Director of 
the Botanic Garden of Harvard University, Massachusetts. 
Plants raised from these flowered in June of the present 
year in the open air. The stems, which become hard and 
woody, were protected in a cold frame in’ winter. 
Deser.—More or less glaucous. Stem two to three feet 
high, woody and branching from the base; branches 
erect, slender, green and red-brown. Lower leaves three 
to five inches long, narrowly oblanceolate, acute, quite 
entire, or rarely with one or two lateral incisions, yellow- 
green ; upper leaves gradually smaller, about an inch long, 
linear, narrowed to the base. Flowers secund, in slender 
terminal and lateral racemes, which are sometimes 
branched at the base, bracteate and bibracteolate ; pedicels 
slender; bracts and bracteoles ovate-lanceolate, one-sixth 
to one-third of an inch long. Calyx small, lobes ovate, 
with recurved tips. Corolla an inch and a half long, 
bright azure or violet blue, rose-purplish towards the 
base of the tube, and on the disks of the lower corolla- 
~ lobes; tube terete, about a third of an inch long, gradually 
dilated into the tubular-campanulate elongate throat ; 
limb broadly two-lipped, three-quarters of an inch broad 
across the tips; upper lip of two broad retuse recurved 
lobes; lower broadly transversely oblong, shortly trun- 
cately three-lobed, the lobes retuse. Stamens included, 
filaments quite glabrous; anthers golden yellow, margins 
of cells shortly villous. Staminodes filiform, tip clavate, 
quite glabrous. Ovary and style glabrous.—J. D. H.
