Figs. i-i8. — Genlisea. 



Fig. 1. — Transverse section through the mouth of a twisted arm, being I 



an amplified figure of part of fig. 4 {cf. 11 — 10, at j). i 



Fig. 2. — Section through the mouth at the top of the neck {11 — 10 at 5) 



showing the rows of detentive hairs. 

 Fig. 3. — Section through the mouth at the top of the neck (// — 10 at 



5) showing particularly the giant articulating hair ("distance piece"). 

 Fig. 4. — Section across arm (// — 10 at j). The obliquity of the rows 



of detentive hairs is to be noted. 1 



Fig. 5. — Transverse section through neck {11 — 10 at i), at the level j 



of the row of glands, indicated by is, fig. 9, which is a longitudinal ^ 



section in the same region. ! 



Fig. 6. — Transverse section through neck at 2 (11 — 10), through the | 



basal cells of the detentive hairs. ' 



Fig. 7. — Transverse section through a ridge in the belly of the flask 



(7/ — 10 at 4). 

 Fig. 8. — Longitudinal section with perspective at 2 (// — 10). Inter- 

 cellular spaces are hatched. I 

 Fig. 9. — Longitudinal section at / (// — 10) and approximately in the 



plane in which one of the vascular strands lies. ^ 1 



Fig. 10. — Longitudinal dorsi-ventral section showing also the interior of 



the belly of the flask. 

 Fig. II. — Mucilage gland from external surface lies. 

 Fig. 12. — Short detentive hair from edge of arm. 

 Fig. 13. — Detentive hair from interior of arm or neck. 

 Fig. 14. — Glandular hairs (presumably digestive) from belly of flask. 

 Fig. 15. — Articulating hair ("distance piece") from edge of arm. 

 Fig. 16. — Glandular hair from interior of upper part of neck and of the 



arms. 

 Fig. 17. — Digestive hairs with four celled capital. Otherwise as in fig. 



14- 

 Fig. 18. — View of the depression into which the large giant cell of a dis- 

 tance piece fits.
