Figs. 1-20. — Nepenthes. 1 



Figs. 1-3. — Stellate hairs, sometimes emergent, sometimes in pits. 



Fig. 4. — Tufted hair, producing the rusty pubescence of Nepenthes. 

 There are several varieties of form. 



Figs. 5 and 6. — Front and lateral views of the peculiar stomata on the ' 



waxy zone of the interior of the pitcher. ' 



Fig. 7. — Front and lateral views of the epidermis clothing the peristome; , 



a-b and c-d correspond in position. N. ampuUaria {of. figs. 17 and 

 18). 



Fig. 8. — Nectar gland from inner surface of the lid. 



Figs. 9 and 10. — Digestive glands from two species, in section; cut. 

 suberized course of cells. 



Fig. II. — Front view of a digestive gland, standing in its pocket. , 



Fig. 12. — Epidermal cells of the peristome of N. Lowii. 



Fig. 13. — Nectar gland of the peristome edge, N. ampuUaria. The 

 outermost course of cells is suberized. 



Fig. 14. — Digestive gland in young, thin-walled condition of N. ampul- 

 lar ia. 



Fig. 15. — External alluring (nectar) gland from the midrib of the blade. 

 S, suberized layer. 



Fig. 16. — Nectar gland from the ridge beneath the lid, of N. Tiveyi. S, 

 suberized course of cells. 



Fig. 17. — Transverse section of epidermis of the peristome of A'. am- 

 puUaria. The cells appear ridged. 



Fig. 18. ^ The ridges are seen to be due to the overlying of next cells 

 (see also fig. 7). 



Fig. 19. — Quite young stage of development of a pitcher and lid in sec- 

 tion, showing folding of the lid and origin of the inner peristome ridge 

 as an outgrowth of the wall. 



Fig. 20. — Transverse section of the petiole showing it to be bifacial.
