522 BORAGINEZ. 
leaves were 44 by 2 inches, gradually decreasing to J inch; 
both sides of the leaves are thickly studded with calcareous 
tubercles which support stiff, white, calcareous bristles. Heads 
of flowers scorpioid and branched, thickly studded with white 
stiff bristles; bracts lanceolate to linear lanceolate, bristly ; 
calyx half an inch long, 5-partite; segments linear-lanceolate, 
bristly; peduncles very short when the plant is in flower, 
lengthening to half an inch when in seed, and becoming studded 
with calcareous spots; pistil hairy, bifid at the apex, double 
the length of the calyx ; corolla one and a half inch long, half 
an inch wide at the throat, funnel-shaped, almost bilabiate, qa 
externally hairy, 5-lobed, two upper lobes longest, throat of 
corolla glabrous, naked; stamens five, attached, a few long, 
weak hairs between the stamens; the fruit consists of oblong 
rugose nuts, ¢ to ;5; of an inch long, supported upon bony cups 
one-twelfth of an inch in diameter. If long kept the flowers 
lose their deep blue colour and turn reddish. 
Chemical composition.—In boraginaceous plants there occurs 
a nitrogenous substance differing from gluten, the solution 
of which in boiling water jolidites on cooling to an imperfect 
jelly, and is precipitated by acids. It is also precipitated by 
the alkaline earths and by most salts, but tannin merely clonds it. 
(Braconnot, J. Phys. 84, 274.) In Gaozabén this nitrogenous 
substance is particularly abundant. 
The ash of the leaves and stalks of Gaozab4n has been 
examined by Deshmukh (1884), with the following results:— 
Silica, 24°17; Carbonic acid, 15°71; Alumina with traces of iron, 
1°87; Lime, 27-31 ; Magnesia, 2° 77; Potash, 14°56; Soda, 9°51; 
Sulphuric acid, 1° 79; Phosphoric acid, 1 06 ; PGilacina, 14th
