Hab. Between Lakes Stefanie and Kudolf, July 9tb, 1895. 



The specimen consists of a long slender branch 6' 5 dm. long, 

 1-5 mm. in diameter, and bearing near the top a very few slender 

 opposite flowering shoots. The leaf-stalk is 1-2 mm. long, the 

 blade 1*5-2 cm. by 5-6 mm. broad or smaller, the lower margins 

 bear a few long cilife. The bracteoles are reduced to minute and 

 fleshy teeth less than 1 mm. long. The calyx is deeply 5-partite, 

 the segments 3'75-4-5 mm. long. The corolla-tube is 5 mm. 

 long, 4 mm. in diameter at the mouth ; the upper lip, 8 mm. long 

 is broadly sac-like below and bluish in colour, marked internally 

 with sharp longitudinal dark blue lines, the upper free margin is 



2 by 3 mm. ; keels start each from a tufted oblique crest just below 

 the level of the stamens and run upwards, converging to within 



3 mm. of the top. The lower lip is 11 by 10 mm. the central 

 lobe is the larger. The filaments, 5 mm. long, are erect and 

 parallel with the upper lip, the anthers being almost on a level with 

 the top of the lip. The lower half- anther is 1-5 mm. long, its flat 

 curving appendage (1 mm. long) ends with a triangular notch. 

 The upper half-anther is a little more than 1 mm. long. The 

 filiform style, 7 mm. long, is sparsely puberulous at the base. 

 The four-seeded capsule is 12 mm. long. 



In habit and foliage this species recalls some of the small- 

 leaved forms of J. insalaris T. Anders., but it is at once dis- 

 tinguished by its larger ventricose flowers.
