XCVIII. ACANTHACEiE (CLARKE). 



[Justida, 



Leaves J in. long, very glabrous 

 Capsule hairy. 



Leaves oblong, scabrid hairy .... 

 Leaves lanceolate to linear, glabrate . . . , 

 Leaves ovate to lanceolate, hairy 



j-fHarnieria. — Branches herbaceous ; internodes long. 

 Leaves more or less hairy. Flowers several or one in a 

 cluster. Capsules normal, 4-seeded ; and also (often 

 mixed therewith in the same cluster) abnormal, ovoid, 

 Bubpyramidal, 1-seeded capsules, with strongly toothed 

 wings. — N.B, In J. Mollugo, J. shehelensis, J. hetero- 

 carpa, var. /9, and in J. lepfocarpa no abnormal 

 capsules have been seen, and the plants may prove to 

 belong to groups f or ttt- Further, the typical 

 dimorphic-fruited J. Melampyrum was esteemed by 

 Oliver to be possibly only a seasonal form of 

 J. instilaris, T. Anders, in group f. 

 Flowers 5 in. long at least. Normal capsules more than 

 \ in. long. 

 Lower leaves ovate-lanceolate, base acute 

 Lower leaves long-petioled, base rounded 

 Leaves \ in. long, obovate, snbsessile 

 Flowers scarcely \ in. long. Normal capsules less than 

 \ in. long. 

 Lower leaves ovate-lanceolate. Flowers sessile. 



Sepals ^ in. long. Normal capsules ^J in. long . 

 Sepals i in. long. Capsule \ in. long . 

 Lower leaves oblong-elliptic. Flowers subcymulose . 



•fffFlowers scattered, many solitary, or axillary on short 

 pedicels ; but clusters of 3-1 flowers frequently occur. 

 [These form a badly-limited group, placed with 

 Gendarussa by T. Anderson and Bentham. I do not 

 see any particular affinity between J. Gendarussa and 

 J. odora (the "type" of the present group), but I 

 have 110 great improvement in the arrangement to pro- 

 pose.] 



Mature leaves glabrous ; in J. Fischeri sometimes with 

 a few bristles on the margins. [Corolla |-§ in.
