Stem herbaceous, erect, terete, thinly glandular ; 1st internode 

 2-5 mm. long ; 2nd shorter. 



Leaves simple, cauline, alternate, exstipulate, thinly glandular, 

 tapering into the petiole which is slightly channelled above, and 

 semiamplexicaul at the base ; principal veins traversing the leaf 

 longitudinally. 



No. 1. Narrowly spathulate, entire, obtuse, mucronate. 



Nos. 2 and 3. Narrowly spathulate, tapering into a slender 

 petiole, with one or two teeth on each side near the apex. 



No. 4. Spathulate, deeply incise-dentate with distant teeth. 



Nos. 5-9. Deeply pinnatifid with linear-oblong, horizontally 

 spreading segments. 



Brachycome iberidifolia, Benth. 

 (fig. 457). 



Primary root tapering down- 

 wards, with lateral fibres, annual. 



Hypocotyl erect, terete, very 

 short, tapering indistinguishably 

 into the root. 



Cotyledons short, oblong, obtuse, 

 entire, fleshy, convex on both sur- 

 faces or nearly flat above, tapering 

 to the base, then connate and form- 

 ing a cup around the plumule, with 

 an indistinctly discernible midrib, 

 glabrous, light green or stained 

 with red beneath, 4-4-5 mm. long, 

 1-75-2 mm. wide. 



Stem herbaceous, annual, erect ; 

 primary internodes short or not 

 developed. 



Leaves simple, radical and cau- 

 line, alternate, exstipulate, pelio- 

 late, or narrowed to the base and not truly petiolate, alternately 

 but indistinctly penninerved, fleshy or subsucculent, glabrous, light 

 green above, paler beneath, petiole or petiole-like base, channelled
