Hypocotyl 5 mm. long, terete, thickest at base, pinkish, 

 especially towards cotyledons. 



Cotyledons oblong, petiolate, bright-green or purplish-red 

 throughout, obtuse, entire, with margin ciliated with glandular 

 hairs; lamina 4mm. x 3mm., horizontal, bent almost at 

 right angles to the nearly vertical petiole; petiole 1*15 mm. 

 long, semi-erect or nearly vertical, channelled on upper sur- 

 face, connate and slightly swollen at base. 



Plant with nine leaves : Remains of cotyledons and 1st leaf 

 show the lowest leaf to be the second. 



2nd leaf (fig. 39) 5-5 mm. x 325 mm., ovate in outline, 

 bright reddish-purple on both surfaces, coarsely and deeply 

 toothed so as to be almost pinnatifid or lobed, and each tooth 

 ending in a swollen apiculus, ciliated and sparsely hairy on 

 both surfaces with simple and also with glandular hairs \ 

 midrib sw T ollen on under-surface of leaf; petiole half the 

 length of lamina, channelled above. 



3rd leaf 6 mm. x 3 - 75mm., similar in other respects to 

 2nd leaf. 



4th leaf 12 mm. x 5 mm., very similar in all other respects 

 to 2nd leaf, but with four teeth on one side and three on the 

 other ; lamina 7 - 5 mm. x 5 mm. ; petiole 5 mm. long. 



5th leaf similar to 4th leaf, but with longer petiole. 



6th leaf lanceolate, horizontal, with apex sloping towards 

 ground, subtruncate at base, 5-toothed on each side; lamina 

 10 mm. x 6 mm.; petiole 8 mm. long, sheathing at base, 

 deeply and narrowly channelled down upper surface, inserted 

 on stem at angle of 45° ; edge of channel very thick. 



8th leaf lanceolate, subcordate, very dark-purple, almost 

 black on upper surface, much paler and rather grey beneath, 

 irregular and deeply serrate; lamina 2-12 cm. x 8-3 mm. ; 

 petiole 3-2 cm. long; margin ciliated with long white and 

 also with glandular hairs, sheathing at base ; midrib, veins, 

 and swollen apiculi of teeth pink. 



9th leaf (in process of development) : Lamina almost 

 opened out, 12 mm. x 3 mm.; petiole 2-4 cm., with two- 

 prickles. 



Stipules inserted at upper end of sheath, linear or almost 

 filiform, ciliated, often bent downwards. 



Stem of slow development, partly enclosed by sheathing 

 leaf-bases ; internodes 1 mm. long or a little more. 



From the above description it will be seen that there are 

 two distinct forms of seedling leaves, the first ovate or cor- 

 date-ovate, with a very deeply cut lamina and petioles shorter 

 or only a little longer than the lamina ; the second lanceolate 

 or narrow-lanceolate, extremely dark in colour, not so deeply 

 toothed as the first type of seedling leaf, but of much greater 

 size and with the petiole always longer than the lamina.
