212 THE JOrRNAL OF BOTANY 



Fig. 5. E. atro-pnTpurea x JE. latifolia. We give the lip of this 

 hybrid for its general interest — the inflvience of E. afropnrpiirea may 

 be seen in the bosses, but, of course, the determination of the hybrid 

 was largely connected with the rest of the plant. Note the distinctly 

 incurved edges of this lip. 



Figs. 8 to 23, and fig 25. E latifolia. 



Here it should be noted that there is not much to be gained by 

 considering the relative length and breadth of the lip. It varies very 

 much, and there are so many degrees of curling under of the tip that 

 this affects the appearance when the lip is seen from the front — many 

 of the figures look broad because the point happens to be tucked back 

 so as to be invisible. 



Fig. 8. (Canterbur}^) Lip with 3 quite distinct bosses, not 

 smooth. Leaves of this plant were of medium breadth, passing 

 gradually into bracts. 



Fig. 9. (Owl Wood, Surrey.) Lip with two clearly marked off 

 side-bosses, which are very finely wrinkled with a minute but definite 

 centre-boss between them. Leaves of the broad type with abnipt 

 transition to bracts. 



Fig. 10. (Cardigan.) A lip Avith 3 bosses, the central one large 

 and prominent, all three of them with a few simple wrinkles. Leaves 

 of the '* media " type. 



Fig. 11. (Cardigan.) A slenderer lip than 10, with the tip not 

 curled under. Bosses forming a rather vague generalised elevation 

 and fairly smooth. Leaves fairly narrow. 



Fig. 12. (Cardigan.) This shows the extreme wrinkled type, and 

 the three bosses more or less confluent. 



Fig. 13. (Cardigan.) This is a lip with well-separated, smoothish 

 side-bosses, with a shallow central elevation, not a concentrated boss. 

 Leaves moderately broad below, grading off into bracts. 



Fig. 14. (Cardigan.) Bosses slightlv marked and fairly smooth, 

 slight central ridge. Leaves of almost the narrowest type, transition 

 to bracts not very gradual. 



Fig. 15. (Cardigan.) Smooth bosses and a wide central groove. 

 Leaves narrow. 



Fig. 16. (Cardigan.) The bosses here are concentrated into 

 a knot in the middle, and there is a long shallow median tongue. 

 Leaves all broad. 



Fig. 17. (Cardigan.) Minute distinct centre-boss and fairly 

 rugged lateral bosses. 



Fig. 18. This is a lip from a plant sent us by Eev. E. F. Linton 

 as probably E. atroviridis. The central boss is not so much a boss 

 as a ridge, the side-bosses are fairly wrinkled in a slight way. The 

 leaves were of medium width, the graduation to bracts not very 

 gradual. Leaves curiously acuminate from a broad base. 



Fig. 19. (Cardigan.) "^Slightly wrinkled side-bosses and central 

 ridge. Leaves broad with very abrupt transition from large upper 

 leaf to small lowest bract. 



Fig. 20. (Cardigan.) Central ridge and slightly wrinkled side- 

 bosses. Leaves so "broad below as to be orbicular, but gradually 

 tailing off by many gradations into narrow bract-leaves above.
