 Leaves 4 J by 2 in., broad-elliptic, acuminate at either end ; petiole 

 J-1 in. long. Spikes 8-13 by h 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 6, ^ in. long, subequal, linear. Corolla h in. long. One

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 Acanthacece, 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, Lindau in Engl. Jahrb. xx. 72. Small herb. 

 Leaves 1^- by f in., elliptic, hairy, subsessile. Inflorescence terminal, 

 -J in. long, dense ; bracts f by j?^- in., very hispid ; bracteoles 4 in. long, 

 linear. Sepals f in. long, linear-oblong, white-edged, hispid. Corolla 

 f in. long. Lower anther-cell tailed. — Lindau in Engl. & Prantl, 

 Pflanzenfam. iv. 3 B. 349.

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 i in., ovate, acute, glabrous. Spikes terminal, 

 loose, short ; bracts | in. long, lanceolate ; bracteoles minute. Sepals 

 ^ in. long, subulate, glandular, hairy. Corolla green or light violet ; 

 tube J in. long and more ; limb \ in. long. Lower anther-cell tailed. 

 Fruit wanting.
