(2) Cotyledons (Petiole, taper). 



V-shaped, about as long as the filiform petiole, not tapering, usually spread! rg. 



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



Green, with sometimes a purple tip (W.A.): green (Cow Cowing). 



(3) Stem (Miss Flockton). 



Angular, prominent oil-glands, crimson (W.A.); angular, red (Cow Cowing); 

 crimson (W.A. No. 2). 



(4) 1st Pair of Leaves (Petiole, shape, vestiture). 

 Shortly petiolate. linear or less than a line broad, glabrous. 



(5) Subsequent Pairs of Leaves (Number, shape, vestiture). 



Two. linear, glabrous. The next four or six leaves are linear, alternate, and 

 above them the leaves again become opposite, and vary from linear-lanceolate to 

 cordate-lanceolate, sessile. They then pass from this stage into broad -lanceolate, 

 decurrent and finally winged, decussate, spreading or recurved. One drawing shows 

 them still opposite at 23 in., and 3 cm. long and 1-5 cm. broad. As they approach the 

 alternate stage they are less winged, becoming decurrent and finally shortly petiolate. 

 The colour throughout the various stages is glaucous. Stems quadrangular, winged. 



(6) Intermediate Leaves. 



Long narrow lanceolate, curved inwards, decurrent to short!} 7 petiolate, 8 cm. 

 long, 1-5 cm. broad, light green shaded glaucous. 



(6a) (Miss Flockton). 



1st leaves narrow linear, alternate. The first leaves are alternate, afterwards 

 becoming opposite. As development proceeds, and while the leaves are opposite, 

 they become decurrent in a remarkable degree (W.A.). 



1st leases very narrow-linear, channelled and inclined to become alternate at once, 

 decurrent. Note, leaves decurrent and stem angular (Cow Cowing). 



1st leaves, linear. After the linear leaves, the next are winged and decurrent, 

 broad at the base and tapering to a fine point. Very glaucous (W.A., No. 2). 



Series 6.— At first linear, then short and broad. 



E. leptophylla. E. calycogona. 



E. gracilis. 



General Appearance.— Slender, semi-glaucous, at first slender with fairly numerous 

 linear, erect or spreading leaves, then changing to short lanceolate, and, in some cases, 

 to almost elliptical-lanceolate, rarely reaching two inches long throughout.
