Delphinium Brownii 
Perennial : stem about 1 m. high, glabrous and shining through- 
out, simple: leaves palmately divided into about 5 divisions, 
puberulent ; lower petioles 8-10 cm. long ; divisions 4-6 cm. long, 
oblanceolate in outline, once to twice cleft into lanceolate, acute, 
somewhat spreading lobes: inflorescence a rather lax raceme; 
bracts linear ; pedicels slender, 1-2 cm. long, almost erect, ‘curved 
and twisted; upper portion sometimes slightly puberulent ; bract- 
lets linear-subulate, small, 3-4 mm. long: sepals dark blue or 
purple, oblong-oval, obtuse or the lower and upper acutish, 10-12 
mm. long: lateral petals also blue or purplish ; blade cleft only 
about one third its length; upper petals of the same color or 
paler, obliquely cuneate, acute ; spur short and rather thick, I cm. 
or less long, straight and ascending : follicles erect, glabrous. 
This is nearest related to D. glaucum, but differs in the puberu- 
lent leaves with narrower segments, the lax raceme with more 
erect pedicels and the darker flowers.

‘ Delphinium elongatum 
Tall perennial with a short woody caudex: stem glabrous and 
glaucous up to the inflorescence, which is slightly strigose : leaves 
digitately. divided into about 7 divisions, glabrous and glaucous 
beneath ; petioles fully 1 dm. long; divisions of the blade oblance- 
olate in outline, 5-7 cm. long, cleft into lanceolate, acute lobes : 
inflorescence strict and elongated ; bracts small, linear, almost fili- 
form; pedicels 1-2 cm. long, at first ascending, in fruit almost 
erect ; bractlets minute, subulate : sepals and petals dark blue, the 
former oval, obtuse or acutish, about 1 cm. long; spur short, 
straight, about 12 mm. long: lateral petals cleft at the apex, mee 
or less toothed: follicles erect, 12-15 mm. long, strigose-puberulent. 
In some respects nearest to D. glaucum, but differing im the 
puberulent pod, strigose pubescence at least on the pedicels, ee 
the narrower divisions and lobes of the leaves. It grows at an alti- 
tude of about 2000 m.
