i'l) Hypocolyl. 

 E. Gillii, medium to long. 

 E. cruris, medium to long, filiform. 

 E. Kruseana, long. 

 E. uncinate/,, long. 

 E. decurva. medium. 



(la) Hypocotyl (Miss Flockton). 

 E. Gillii, crimson (Flinders Kange) ; terete, red (Broken Hill). 

 E. cruris, terete, wiry and red, glaucous towards cotyledon and stem (Southern 

 Cross). 



E. Kruseana, terete, slight, weak, tinted pink. 



E. uncinata, terete, red, wiry (Cow Cowing); terete, pink, wiry (Hopetoun); 

 terete, wiry, slightly tinted red (Bremer Bay). 



E. decurva, pink (W.A.). 



(2) Cotyledons (Petiole, taper). 



E. Gillii, Y-shaped, about as long as the petiole, sometimes curved and spreading, 

 slightly tapering into the petiole. 



E. cruris, V-shaped, about as long as the petiole, which is sometimes filiform, 

 slightly tapering into the petiole when broad. 



E. Kruseana. V-shaped, about as long as the filiform petiole, oblong, acute, not 

 tapering. The smallest of this series. 



E. uncinata. V-shaped, longer than the short thickish petiole, oblong-lanceolate, 

 not tapering. 



E. decurva. crescent-shaped, broad, slightly tapering into the petiole, the lobes 

 shorter than the petiole, glaucous. 



(2a) Cotyledons (Undersurface, Miss Flockton). 



E. Gillii, green (Flinders Range); purple tint (Broken Hill). 



E. cruris, glaucous-green. 



E. Kruseana, green. 



E. uncinata, green (Cow Cowing and Hopetoun). 



E. decurva. horizontal. We have two pairs of cotyledons parallel to each other. 

 As growth proceeds we have crutch-shaped cotyledon leaves with petioles. 



(3) Stem (Miss Flockton). 



E. Gillii, angular, shaded red (Flinders Range): slightly angular, red (Broken 

 Hill). 



E. Kruseana, weak, terete, red at the base, shading to pink and later powdery
