648 Flora of the Malayan Peninsula. 



seeds small, ovoid, flattened, brown, shaggy on the margin, with hygro- 

 scopic hairs. C. B. Clarke in Hook. f. Fl. Br. Ind. IV. 409. Justicia

Nees himself, in DC. Prodr. XI. 722, united this species to N. corymbosa, Blume 

 Bijdr. 804 (1825) ; the latter is (when dried) a smoky grey-green ; the pedicels and 

 calyx have viscous (and often glandular) hairs. The two are very close together. 



2. NoMAPHiLA MINCE, C. B. Clarke, n. sp. Smaller in all its parts 

 than N. stricta. Leaves : lamina scarcely 2 in. long. Cor^/mft-branches 

 slender, glabrate. Corolla -25 to -35 in. long. Anthers and pollen 

 smaller. Capsule '25 to '35 in. long. N. stricta (partim), C. B. Clarke 

 in Hook. f. Fl. Br. Ind. IV. 409. Buellia ? paniculata, Herb. Bottler. 



Peeak : Scortechini 1374. — The example in Herb. Eottler is without 

 locality. 



7. EuELLiA, Linn. 



Herbs or undershrubs. Leaves opposite, subequal, entire ; upper 

 surface with rhaphides. Floioers axillary (or panicled in American 

 species) ; bract ; prophylla spathulate or subfoliaceous, exceeding the 

 calyx. Calyx deeply 5-fid ; segments subequal, linear. Corolla tubular- 

 ventricose, blue to white ; lobes rounded, twisted to the left in the bud. 

 Stamens 4, didynamous ; filaments glabrous ; anthers of 2 oblong, sub- 

 equal, parallel, muticous, glabrous cells ; pollen globose, large (30 to 

 50 /x in diam.), honeycombed. Ovary glabrous; ovules 3 to 10 in each 

 cell ; style hairy, with one linear branch, the other obsolete. Capsule 

 clavate; base solid, sterile; top ellipsoid or subglobose, with 6 or 

 more close-packed seeds ; retinacula large, hooked. Seeds ovoid, 

 flattened, hygroscopically shaggy on margin. — -Species 150 (Bentham) 

 or 200 (Lindau), in the warmer parts of the world, more abundant in 

 America. 



But a considerable number of the species reckoned in Ruellia by Lindau have 

 not " wabenpollen " (honeycombed pollen), but " stachelpollen " (prickly pollen) ; so 

 that the species left in Ruellia may not be more than 120 to 150, and possibly may be 

 much fewer, if (as in the above diagnosis) the genus iS' restricted to those plants 

 which have a stalked clavate capsule [Dipteracanthiis (genus), Nees]. 



1. Ruellia eepens, Linn. Mant. 89 (1767) (7io^o/ Burm.). Sparingly 

 hairy or glabrate. Stem 6 to 20 in., weak, often much branched.
