Bootstock slender creeping, stem 25 — 30 cm. simple or branching 

 at the base, radical leaves very small (1* cm. long 0'75 cm. wide, petioles

 hind and marginally 5-muconate or 5 — 10-spined. Corolla tube included, 

 obliquely annular within, slightly enlarged upward, limb 2-lipped, upper 

 erect concave entire or emarginate, lower 3-fi.d, lateral lobes oblong sub- 

 erect, mid-lobes spreading obcordate. Stamens 4, ascending didynamous 

 lower longer, anthers conniving 2-locular. Style 2-lobed, lobes subequal 

 subulate. Nutlets triquetrous truncate smooth. — Species 3, Mediterra- 

 nean and Orient. 



§ § Chasmonia ; calyx-limb 2-lipped, prolonged behind as an ei'ect 

 spinescent tooth and in front as a spreading 3- parted lip with smaller 

 radiating marginal lateral spines. 



1. Molucella otostegioides Prain; glabrous, leaves sessile lan- 

 ceolate acute quite entire nerveless, bracts 3-partite subulate spinescent. 



N. W. Frontier; Suleiman range, in the Zam defile leading to 

 Waziristan, 3500 feet, Stewart. 



Erect, branches slender 4-angled, green, leaves 4 cm. base narrow- 

 ed, tips sharp but hardly pungent, whorls distant, bracts all spiny, calyx

 throat naked, upper tooth 6 mm., lower 3 mm. long 4 mm. across, corolla
