194 XCVIII. ACANTHACEA (CLARKE). [ Justicia. 
26. J. stachytarphetoides, C. B. Clarke. Hairy, 3-8 ft. high. 
Leaves 44 by 2 in., broad-elliptic, acuminate at either end; petiole 
3-1 in. long. Spikes 8-13 by } in.; lowest whorls 1 in. apart, upper 
confluent, 3—1-flowered ; outermost bract (floral leaf) } in. long, elliptic, 
acute; bract and bracteoles (or sterile bracts?) } in. long, lanceolate, 
hairy. Sepals 5, 1 in. long, subequal, linear. Corolla $ in. long. One 
anther-cell lower than the other, oblique, long-tailed ; pollen ellipsoid, 
with 2 longitudinal bands, large stopples, no tubercles. Young pistil 
glabrous.— Duvernoia stachytarphetoides, Lindau in Engl. Pf. Ost-Afr.

The capsule has not been seen, and possibly may be densely minutely hairy, 
though the young pistil is glabrous under the microscope, It is difficult to form 
genera that are “natural” in the Order Acanthacee, but it is surely too un- 
natural to place this species under Duvernoia, Lindau appears to have done this on 
one character only—viz., that the lines of tubercles often seen on the smooth bands 
of the pollen in Justicia are here not actual tubercles, but obscurely indicated by 
markings (as is the case in some species placed by Lindau in Justicia). 
27. J. togoensis, Lindaw in Engl. Jahrb. xx. 72. Small herb. 
Leaves 14 by ? in., elliptic, hairy, subsessile. Inflorescence terminal, 
2 in. long, dense ; bracts 3 by j4; in., very hispid; bracteoles 3 in. long, 
linear. Sepals 2 in. long, linear-oblong, white-edged, hispid. Corolla 
2 in. long. Lower anther-cell tailed.—Lindau in Engl. & Prantl, 
Pflanzenfam. iv. 3 B. 349. 
Upper Guinea. Togoland, Biittner, 222! 
The example is young, the spike not grown out; the affinity is perhaps with 
J. flava, as Lindau suggests. 
28. J. ulugurica, Lindau in Engl. Jahrb. xxii. 126. Branches 
woody. Leaves 1 by $ in., ovate, acute, glabrous. Spikes terminal, 
loose, short; bracts } in. long, lanceolate; bracteoles minute. Sepals 
3 in. long, subulate, glandular, hairy. Corolla green or light violet ; 
tube } in. long and more; limb } in. long. Lower anther-cell tailed. 
Fruit wanting.

29. J. diffusa, Willd. Sp. Pl. i. 87. Stems 8-24 in. long, week, 
hairy. Leaves 1} by 4-3 in., elliptic or ovate, narrowed at either end, 
sparsely hairy; petiole 0-3 in. long. Spikes 1-14 by }-} in., sparsely 
hairy ; bracts } in. long, narrow-lanceolate, green with scarious margins ; 
bracteoles similar to the bracts but smaller. Sepals 4,4 in. long; 
narrow-lanceolate. Corolla } in. long, purple or rose. Filaments 
glabrous ; one anther-cell below the other, tailed ; pollen ellipsoid, with 
2 longitudinal bands, not tubercled. Ovary nearly glabrous; style 
thinly hairy, branches 2, subequal, minute. Capsule $ in. long,
