This species is manifestly close to J. stachytarphetoides ; the inflorescence and 
flowers are very similar though smaller; the leaves are diverse. 
23. J. longecalcarata, Lindau in Engl. Jahrb. xx. 73, Innova- 
tions dense with yellow strigose hairs. Leaves 3 by } in., glabrate 
except for obscure hairs on the midrib beneath; petiole } in. long. 
Spikes }—? in. long, hairy; bracts and bracteoles linear-oblong, obtuse. 
Calyx, corolla, stamens, and pistil nearly as of J. flava. Capsule } in. 
long, 4-seeded, glabrous.—Lindau in Engl. & Prantl, Pflanzenfam. iv.

Kilimanjaro, 2200-2600 ft., Volkens, 563! 
In Volkens, 2184, the entire spikes are hardly 3 in. long; the fine examples of 
Gregory have inflorescences up to 9 in. long; the lowest whorl of flowers 2} in. 
distant. 
24. J. tanaensis, (. B. Clarke. Branches 2 ft. long, glabrate, 
full of cystoliths ; innovations with strigose hairs. Leaves 34 by 1} in., 
narrowed at both ends, nearly glabrate, full of cystoliths ; petiole }—1 in. 
long ; upper leaves smaller, passing gradually into floral leaves, 1° *}in. 
Spikes terminal, interrupted, nearly glabrous; flowers 3-1 in each 
floral leaf-axil. Sepals 5, } in. long and upwards, linear-oblong, white- 
margined, slightly scabrous. Corolla } in. long or rather more, bluish

Capsule 4 in. long, rather stout, 4-seeded, glabrous. 
Nile Land. British East Africa: Tana River, Thomas, 38! 
The smooth capsule brings this next J. longecalcarata. The long-petioled green 
leaves do not match.

branches grey-tomentose. Leaves 3 by }—} in., elliptic to round, grey- 
tomentose or finally nearly glabrate ; petiole 0-} in. long. Spike 24 by
