Root (or rhizome ?) long woody brown, sending up fascicles of short stout erect 

 stems as thick as a crow-quill, and covered with smooth glistening white bark, from 

 which again arise fascicles of erect annual simple or sparingly divided branches 6-1 

 in. high ; nodes of the stem below shortly sheathed with membranous bases of old 

 leaves. Leaves \~\ by ^-J in., coriaceous, margins and midrib scabrid. Cymes 

 axillary and terminal, shorter than the leaves, or flowers solitary on long axillary 

 peduncles. Flowers rather large, J in. diam. Corolla- segments lanceolate, acute. 

 Anthers globose. Fruit ^ in. diam., smooth.- — The habit of this species is very 

 peculiar, like that of some Galia. 



8. R. albicaulis, Boiss. ; vm: stenoptylla, JBoiss. Fl. Orient, iii. 19 ;

Stem woody below; branches rather stout, often white, quite smooth, upper green 

 with white thickened angles. Leaves 1-4 by ^-^ in., midrib and thickened margin il 

 nerve almost quite smooth. Cymes axillary and terminal, much shorter than the 

 leaves, many-flowered; peduncles and pedicels stout. Flowers minute, yellow. 

 Corolla^segments lanceolate, acuminate. Anthers ovoid. Fruit smooth. — The flowers 

 of Boissier's specimen of his var. Kotschyi, from. Sohiras, are smaller and more 

 rotate than Griffith's Affghauistan ones, which he refers to it. They are funnel- 

 shaped and glabrous in the Murree, &o., specimens. 



90. GAXiXVia, Linn. 



Glabrous, hispid, scabrid or prickly erect or scandent weak herbs ; branches 

 square. Leaves 3 or more in a whorl, rarely opposite and stipulate, broad or

 yellow or greenish ; pedicel jointed with the ovary. Calyx-tube ovoid or 

 globose; limb 0. Corolla rotate or shortly funnel-shaped, lobes 4, rarely 3, 

 valvate. Stamens 4, rarely 3, in the corolla-tube ; filaments .«hort ; anthers 

 didymous. Ovnry 2-celled ; style short, arms 2 with capitate stigmas ; ovules 1 

 erect in each cell, attached to the middle of the septum. Fi-uit small, didy-
