12. J. phyllostachys, (’. B. Clarke. Hairy ; branches 2 ft. long, 
angular, dividing. Leaves up to 4 by 12 in., narrowed at both ends; 
petiole 14 in. long. Spikes up to 24 by 1 in., dense; floral leaves 3 by 
4 in , acute (but the lower are often 1 in. long, approximating to ordi- 
nary leaves, so that the inflorescence appears leafy), with 3-1 flowers 
under each ; bracteoles 2, minute. Sepals 5, subequal, } in. long, linear- 
lanceolate. Corolla up to } in. long; tube linear-cylindric ; very little 
inflated upwards; lips scarcely } in. long, posticous oblong-elliptic, 
subentire. One anther-cell below the other, tailed ; pollen ellipsoid, with 
2 stopples and several rows of tubercles on the bands. Pistil glabrous 
except a few scattered hairs on the style. Capsule } in. long ; 4-seeded, 
glabrous; stalk solid, less than ;; in. long; placente not mising

The Nyasaland plant is the type of this species; the plentiful material varies from 
scabrid to softly hairy. The Angola fragment is imperfect, and appears the same s0 
far as it goes. The lower anther-cell is definitely tailed, but in one example only 
obscurely so,

high, hairy. Leaves up to 5 by 1}in., elliptic-lanceolate, acute at either 
end; petiole 4 in. long. Spikes forming a terminal panicle, 1} by $2» 
or a compound panicle 3 by 2 in., continuous, rather lax ; bract 4-3 2. 
long, lanceolate from an elliptic base, minutely hairy ; bracteoles zm. 
long, similar to the bracts. Sepals 5, 4 in. long, linear or oblong-linear ; 
two anticous rather broader; posticous hardly smaller than the two 
adjacent, but sometimes wanting (fide S. Moore). Corolla 3 in. long; 
violet. One anther-cell below the other, tailed; pollen ellipsoid, with 
2 stopples and single rows of tubercles. Pistil glabrous, except @ few 
minute hairs near the style-base. Fruit unknown.—J. malangamt
