ON SEEDLINGS 



Cotyledons ovate, acute, entire, glabrous, with a distinct midrib, 

 but no other venation discernible, deep green above, paler beneath ; 

 lamina 4-7 mm. long, 8-6 mm. wide ; petiole channelled above, 

 convex on the back, 2-5-6 mm. long, slightly connate at the base, 

 glabrous, dotted with red. 



Stem herbaceous, throwing up 

 annually leafy, flowering stems from 

 a persistent rootstock, quadrangular, 

 densely covered with a glandular 

 pubescence ; 1st internode '5-1*25 

 mm. long ; 2nd l-3'5 mm. ; 3rd 1- 

 10 mm. 



The internodes are more de- 

 veloped when the seedlings are 

 crowded than when they have plenty 

 of space. 



Leaves simple, entire, cauline, 

 opposite, alternately incurvinerved, 

 obscurely reticulate, minutely glan- 

 dular and deep green on the upper 

 surface, paler beneath ; petioles 

 semiterete, channelled above, more 

 or less thinly ciliate along the edges 

 in the seedling stage, but more 

 decidedly so in the adult plant with 

 coarse hairs or fringes, slightly con- 

 nate at the very base. 

 First pair ovate, obtuse, similar to the cotyledons, but slightly 

 larger. 



Second to fourth pairs ovate, gradually larger and more acute.

 Nat. size. 



Asterolinum splendidum, Auct. 



Hypocotyl erect, terete, glabrous, colourless below the soil, green 

 above it, 1-1-5 cm. long. 



Cotyledons linear- oblong, obtuse, glabrous, tapering at the base 

 but scarcely petiolate, entire, 8-10 mm. long, 1-2 mm. wide, bright 

 green, lighter beneath, buds which develop into branches are formed 

 in their axils. 



Stem herbaceous, erect, terete, glabrous, pale green ; 1st inter- 

 node 3-3-5 mm. long ; 2nd only from 1-5-2 mm. 



Primary leaves cauline, simple, opposite, decussate, sessile, entire, 

 linear-lanceolate, acute, glabrous, light green.
