disco ad lineam mediam aculeis 4-5 simplicibus vel glochidiatis 
instructo membrana bullato-calathiformi ad marginem inflexum mi- 
nute dentata intra marginem levi vel rarius tuberculata. 
Has. Upper Beloochistan. No. 933. 
Calyx 14-2 lines long. Corolla 2% lines long. Nuts 4 lines across. 
Flowers purple-red.—Comes very near P. rugulosum, Boiss., and seems 
to differ in its more harsh and spreading pubescence, its larger nuts 
and flowers, and the aculei on the face of the nuts. 
27. Rochelia rectipes, J. E. S.; annua, scabro-hispida, foliis e basi 
semiamplexicauli lineari-acuminatis, racemis elongatis, floribus extra- 
axillaribus, pedunculo florifero sepala bracteasque æquante fructifero 
elongato recto sepala valde aucta erecto-patentia lanceolata in unguem 
attenuata nervo medio pereursa plus minus superante, nuculis rectis 
glochidiato-saccharatis. 
Has. Gurghina, in Upper Beloochistan. No. 978. : 
Readily known by its straight peduncles and sepals. Sepals broad. 
Corolla pale blue, with a white throat. 
LABIATÆ. 
28. Perowskia abrotanoides, Kar.; et atriplicifolia, Benth. 
Both these species grow common in Beloochistan, and the flowers 
and tops are collected and sold in the bazaars, under the name of the 
plant, Tirk, or Gwáree Durnoo. They are supposed to be cooling and 
useful in fever and ague. It may be noted that Karelin, in his de- 
scription of the genus, has reversed the position of the lips of the co- 
rolla, though strangely enough he has kept the perfect or larger stamens 
in their right position, viz., anteriorly. "This may be ascertained by a 
reference to the relation between the odd or posterior segment of the 
calyx and the lips of the corolla, and by the line of origin of the per- - 
fect stamens, which it will be seen is between the anterior and posterior 
lips. The anterior lip is long, narrow, and undivided, and the fissure 
between it and the posterior lip is very deep. The posterior lip is 
made up of the four posterior segments of the corolla, the axile sinus 
being the shallowest. The stamens become finally declinate. The 
posterior stamens are also present, but so very small and imperfect as 
to deserve the name of staminodia only. They are to be seen on the 
upper lip. We may alter the generic character thus :—* Corolle . - -
