Series lc. — Non-Corymbose. 



E. marginata. E. Planchoniana. 



E. Todtiana. E. sepulcralis. 



E. buprestium. 



General Appearance. — Leaves orbicular, oblong to lanceolate, shortly petiolate 

 or sessile, slightly crinkled in the very early stage, flat, or undulate when more advanced, 

 light to dark green or glaucous shaded pink, the veins more or less prominent. Stems 

 usually purple-brown. 



In the intermediate stage E. Planchoniana is the only one of this series which 

 shows a marked affinity to the Corymbosse in the venation, but it is interesting to note 

 that there is a total absence of seta in this species, as well as in the rest of the series, 

 which forms a group with more or less closely corresponding characters in the seedling, 

 but differing materially in other respects. 



(1) Hypocotyl. 



E. marginata. " The hypocotyl is subterranean and extremely short, while 

 this deficiency is compensated for by the length of the petioles." (Lubbock.) 

 E. marginata, very short or submerged. 

 E. Todtiana, short, stout, smooth, reddish. 

 E. Planchoniana, medium to long, stout, reddish. 

 E. sepulcralis, long, slender, reddish. 

 E. buprestium, long, slender, reddish. 



(la) Hypocotyl (Miss Flockton). 



E. marginata, almost without hypocotyl, the stem sometimes springing up from 

 below the surface of the ground (217). 



E. Todtiana, short, terete, reddish. 



E. Planchoniana, thick, red (8-Mile Plains); terete, sturdy, red (Stradbrooke 

 Island). 



E. sepulcralis, sturdy, terete, red. 



E. buprestium, smooth, red. 



(2) Cotyledons. 



E. marginata. Subrotund or transversely oblong, obtuse, emarginate, 

 asymmetrical petiolate, coriaceous, glabrous, dark green, reddish beneath, distinctly 

 trinerved; petioles long, plano-convex, stained with red (Lubbock). 



(Petiole, taper.) 



E. marginata, somewhat cuneate-reniform, slightly emarginate, tapering into 

 the very long petiole. 



E. Todtiana, broad reniform, slightly emarginate, tapering into the petiole, 18 mm. 

 long, 12 mm. broad ; petiole medium, light green, trinerved,
