PENTSTEMON. 



branching mass of some 8 to 20 inches, beset with thread-like foliage, 

 and breaking into loose showers of narrow curved flowers about half 

 an inch in length, and varj 7 ing from white to rosy flesh-colour. 



P. angustifolius is also P. coeruleus, and another queen in the race — 

 a leafy thing of 8 inches or so, forming an almost bushy mass of lovely 

 blue-grey shoots from which later summer elicits spikes of ample 

 blossom such as only the high gods, pillowed on the Empyrean, could 

 have imagined — beginning gently in dreaming tones of lavender and 

 rose, from which the sunlight of maturity stiffens the dawn-softness 

 into clear coerulean tones that herald day, yet never arrive at its hard 

 and shadowless certainties. Not even in Omphalodes is there any 

 matching the tender yet assured magnificence of the pale azures 

 deployed in time by P. angustifolius, which should have the same site 

 and soil as P. alpinus, if long life is desired for its loveliness. 



P. antirrhinoeides need have little note. It is yellow, foot-high, 

 and tender. 



P. arenicola is some 8 inches or a foot tall, with unbranching stems, 

 hairless, and glaucous-blue with oblong leaves. The flowers in their 

 time are no less blue also — tubes of half an inch or so, in short spike- 

 like spires, leafy below. (From sandy deserts in the region of the 

 Central Rockies.) 



P. aridus is a beautiful glandular-downy one-flowered sub-species 

 of P. laricifolius, q.v., with blue blossoms. (From Montana.) 



P. arizonicus is tall and reddish-purple, with smallish flowers, 

 being no more than the variety stenosepalus of P. glaucus, q.v. 



P. azureus is a doubtful name. Plants bought under it ought at 

 least to be of good colour. 



P. baccharifolius should be a scarlet -flowered species from Texas, 

 about a foot in stature. 



P. Bakeri. See P. alpinus. 



P. barbatus is Chelone barbata, a wand-like delicate stem of a yard 

 high or so, set delicately with long thin scarlet tubes. There are 

 many varieties in gardens of this : and all are most daintily effective 

 in drifts and billowing masses of line colour in late summer. 



P. Brandegeei is a variety or sub-species of beautiful P. cyananthus, 

 with thick leathery, fringed leaves, and flowers of pure pale azure 

 suddenly gaping wide, and borne in loose clusters in an almost dense 

 spire. 



P. brevifolius (not P. breviflorus) sends out subterraneous shoots, 

 and is woody and branching, with slender weakly -rising stems spreading 

 about the ground and in length some 4 to 12 inches, set with almost 

 round smooth-edged leaves at the base of the stems and on the barren
