414 DR. DONALDSON SMITh's ACANTHACE^. 



The narrow triangular-pointed segments are 6 mm. long. The 

 corolla is sparsely pubescent ou the outside ; the tube is 2 cm. long 

 by 1-5 cm. broad, and widens abruptly at the mouth. The lobes 

 are 3-5 mm. broad, the longer 6, the shorter 5 mm, long. The 

 filaments are connate at the base, the longer filament of each pair 

 is 2 mm. long, the shorter 1-5 mm. ; the anthers are 1-3 mm. long. 

 The pubescent filiform style is 2 cm. long. The 4-seeded capsule is 

 13 mm. long. 



Resembles some forms of D. radicans 0. K. {Caloplianes radicans 

 Nees) in habit and foliage, but is distinguished at once by its larger 

 fiowers with their long narrow corolla-tube.

 lobis subacutis ; corollre tubo longo parte inferiore tenue, superiore

The species is represented by two small prostrate shoots about 

 5 cm, long and -S-'TS mm. in diameter. They are densely clothed 

 with shore stiff appressed hairs which, except in the upper inter- 

 nodes, spring from the centre of a large pale oval base. Both 

 surfaces of the leaves are covered with similar but rounded placoid 

 scales. The leaves are 8-11 mm. long by 6-7 broad; the blade 

 tapers rapidly at the base into a petiole about 1 mm. long. The 

 shortly hairy calyx is 8 mm. long ; the narrow tube passes into five 

 teeth, 3 mm. long and 1 mm, broad at the base, tapering slightly 

 upwards to the rounded subacute apex. The corolla-tube is 15 mm. 

 long, about f mm. across in the lower half, becoming gradually 

 swollen above to nearly 2 mm. diameter; the lobes are torn, but 

 two are evidently more deeply connate than the other three, which 

 are 5-6 mm. long by 3-5 mm. broad. The four small stamens are 

 inserted in the swollen part of the corolla-tvibe ; the filaments are 

 quite distinct, 1*5 mm. long, the blunt anthers 1 mm. The style is 

 slender, with a clavate tip, and 9 mm. long. 



Apparently near R. somalensis Lindau, from the description in 

 E7i(jl. Jahrb. xx. 14, but evidently a smaller plant, with smaller 

 subsessile leaves and flowers. The squamiform trichomes are also 

 a distinctive feature.
