XCVIII. sodveuacns (CLARKE). 
described as having ovules solitary), the seed in each cell appears basal, the capsule 
having a long empty or solid beak above it. But in most of these species the ovary 
has 2 ovules in each cell, whereof the lower is very much smaller ; in each capsule-valve of 
the ripe fruit a seed is in one cell, and lower down in the other cell the minute point,

representing the small ovule that came to nothing, is not difficult to see. 
Series A. Interpetiolar spines (i.e., reduced leaves of sterile shoots), simple or 
pinnatifid, often present. Posticous sepal often spine-tipped or spine-toothed on 
margin. 
*PRIONITIS.—Lower ovule in each cell minute or 0; 
capsule never having more than 2 seeds, ovoid with 
conic beak. Posticous sepal usually spine-tipped, 
rarely spine-toothed on margin. 
tBracts next the calyx (bracteoles) rigid spines, simple 
or rarely with one lateral basal spiny tooth. 
Corolla 2-lipped; 4 posticous segments in one lip; 
anticous segment clawed, springing from the tube 
lower down. 
Corolla yellow-orange or brownish-red.

“ACANTHOIDEA.—Ovary with 2 similar ovules in each cell ; 
capsule (except by accident) perfecting more than 2 
seeds, 
TBracts next a flower simple spines (see also B. Mar- 
lothiiand B. Kirkii), Hairs simple, often finer 
white hairs with long tawny hairs mixed or on the 
young parts (except B. longissima). Flowers 
(said to be) axillary solitary—i.e., axillary racemes 
reduced to 1-flower with or without a rudiment 
of a second, very rarely 2-flowered.
