VERBEXACEJ3 369 



seedling state at least bears considerable resemblance to a 

 Verbena, and has ovate-oblong cotyledons with a venation 

 similar to that of Verbena officinalis. The first pair of leaves 

 are lanceolate, followed by two pairs which are oblong. All 

 are bluntly serrate. 



A third and distinct type is that represented by Stachy- 

 tarpheta mutabilis which has broadly and roundly ovate, 

 mucronate, and faintly penninerved cotyledons, truncate at 

 the base. The petioles as well as the hypocotyl are hairy. 

 The cotyledons of Ehaphithaninus longiflorus do not conform 

 very closely to the above, but are roundly ovate and one-nerved. 



The cotyledons of Callicarpa aniericana are small, roundly 

 ovate, emarginate, trinerved, pubescent and ciliate. 



The fifth type is represented by Clerodendron Ksernpferi 

 (fig. 586) which has broadly ovate, shallowly and irregularly 

 dentate, penninerved cotyledons, bearing some resemblance 

 to the first pair of leaves but smaller. 



Stachytarpheta mutabilis, Valil. 



Hypocotyl erect, terete, hairy, 2'2-2'5 cm. long, light green or 

 colourless. 



Cotyledons broadly and roundly ovate, obtuse, entire, petiolate, 

 truncate at the base, glabrous, green, indistinctly pimiatinerved, like 

 the leaves ; petioles flat, hairy. 



Stem erect, terete, hairy ; 1st internode 3-4 mm. long. 



First leaves simple, cauline, opposite-decussate, exstipulate, 

 ovate, acute, serrate, pubescent, green, alternately pinuatinerved, 

 petiolate ; petioles short, channelled, pubescent. 



Verbena officinalis, L. (fig. 584). 



Primary root tapering downwards and giving off numerous 

 lateral fibres. 



Hypocotyl short, erect, terete, glabrous, pale green or colourless, 

 3-5 mm. long. 



Cotyledons ovate, obtuse, entire, tapering into the petiole, with 

 a distinct midrib and a few short alternate ascending nerves dis- 

 cernible only by transmitted light, glabrous, light green above, paler 

 beneath ; lamina 3'75-5 mm. long, 2'5-3 mm. wide ; petiole flat 

 above, convex beneath, glabrous, 2'5-4'5 mm. long. 



Stem herbaceous, erect, terete, hairy or pubescent, pale green ; 

 1st internode 1-5-2 mm. long; 2nd 4-6 mm.
