ON SEEDLINGS 



2-75-3-25 mm. wide ; petiole broad, dilated and subconnate at the 



base, 1-1-25 mm. long. 



Stem herbaceous, annual, erect, quadrangular, angles prominent, 



acute, scaberulous with decurved hard points or prickles, glaucous- 

 green, minutely dotted with pale-coloured 

 markings, otherwise glabrous, thickened at 

 the nodes ; 1st internode 3-5-4 mm. long ; 

 2nd 9-11 mm. ; 3rd 1-9-2-2 cm. 



Leaves opposite, decussate or with the 

 stipules appearing verticillate, sessile, with 

 a distinct midrib prominent on the under 

 side, but no other discernible venation hi the 

 fresh state, scabrous and deep green above, 

 glabrous, and paler beneath with a cartila- 

 ginous, re volute margin, connate and together 

 with the stipules forming a little cup round 

 the stem ; stipules one between each pair 

 of leaves, subulate or linear -subulate, 

 acute, revolute at the margin, similar in 

 venation and other respects to the leaves 

 but generally shorter, with their midribs as 

 in the case of the leaves continuous with 

 the angles of the stem, interpetiolar and 

 connate. 



First pairs of leaves lanceolate, longer 

 and much broader than the stipules. 



Second to fifth pairs linear-subulate, 

 acute, similar to the stipules but slightly 

 longer.
