PENTSTEMON Jaffrayanus ; perennis erectus glaber glaucus, foliis omnino inte- 
gerrimis, radicalibus spathulatis in petiolum brevem attenuatis, intermediis 
oblongo-ellipticis, supremis sensim minoribus sessilibus bracteisque cordato- 
ovatis, floribus pseudo-verticillatim paniculatis majusculis, calycis lobis late 
ovatis acutis, corolle pulcherrime czrulez basi fauceque rubree limbo bila- 
biato, filamento sterili elongato imberbi. 
My first knowledge of this lovely and hardy species of Pent- 
stemon was derived from Mr. Jaffray’s collections made at Clear 
Creek, North California, in 1853 (n. 1116 of his specimens). 
Seeds were at the same time sent home by him ; but I know not 
if they ever germinated. Messrs. Veitch and Sons, of Exeter, 
and King’s Road, Chelsea, have been more fortunate with Cali- 
fornian seeds of the same species they received from Mr. William 
Lobb ; and in August, 1857, I had the pleasure to receive living 
specimens here represented. The P. speciosus, Douglas. and 
Lindley (Bot. Reg. p. 1270), from the Strahan River, North- 
west America, is perhaps its nearest affinity, from which it is 
abundantly distinct, and is certainly more beautiful,—for there 
is that mixture in the corolla which is so unusual, viz. of bright 
blue and red, of which however we have an example in the 
Buglosses and some other Boragineous plants. This plant will 
assuredly form an interesting addition to our hardy herbaceous, 
and especially “bedding-out ” plants. It continues to produce 
a succession of flowers in the summer months. . _ 
Drscor. Root perennial. Stems erect, branching only below, 
about a foot high, young ones tinged with red, glabrous, as is 
every part of the plant. eaves all very glaucous, entire ; ower 
leaves spathulate, especially the root-leaves, and tapering below
