Cotyledons shortly and broadly oblong, or oblong-orbicular, ob- 

 tuse, deeply cordate at the base, petiolate, minutely emarginate, 

 radiately seven-nerved from the base, the two upper lateral nerves 

 incurved and uniting with the midrib at the apex, finely reticulate 

 (venation seen by transmitted light only) deep opaque green above, 

 paler beneath, glabrous ; lamina 4-5 mm. long, 3'5-4*5 mm. wide ; 

 petiole semiterete, channelled above, subperfoliate at the base, thinly 

 and minutely hairy, 7-9 mm. long, the margin narrow and colourless 

 with openings into the interior. 



Stem herbaceous, procumbent ; pri- 

 mary internodes undeveloped. 



Leaves compound, radical and 

 cauline, alternate, stipulate, petiolate, 

 thinly and coarsely hairy, light green 

 above, paler beneath ; petioles semi- 

 terete, channelled above, hairy, but 

 sparsely in the seedling, dilated and 

 amplexicaul at the base, proportion- 

 ately much shorter in the adult plant 

 than in the seedling ; stipules none in 

 the seedling or carried up a consider- 

 able way on the petiole and resembling- 

 two small, lanceolate, slightly lobed 

 leaflets, adnate for some distance to 

 the petiole in the adult plant with free 

 lanceolate, acute, green and foliaceous 

 tips, more or less cut. 



No. 1. Trifoliolate or, from the 

 position of the stipular segments, appa- 

 rently five-foliolate ; terminal leaflet 

 cuneate, pinnatifid with narrow, sub- 

 ulate or lanceolate, subacute segments ; 

 lateral leaflets opposite or nearly so, 

 subovate, deeply pinnatifid with narrow, subacute or aristate seg- 

 ments. 



Ultimate leaf oblanceolate-oblong in outline, pinnate ; leaflets 

 oblong, alternate, pinnatisect with numerous alternate, linear-subu- 

 late, acute, aristate segments cut nearly to the midrib. 



The seedling of Acsena millefoliata is very similar to the last, but 

 the hypocotyl is very short and the cotyledons are oval-oblong.
