268 MISS H. BANDULSKA ON THE CUTICULAR STRUCTURE OF 
Sequoia gigantea. 
Fig. 23. Cuticle x 200. Stomatal pores and epidermal cells of which the majority appear 
vertically orientated in this part of the leaf. 
Fig. 24. Cuticle x 540. Part of fig. 23 enlarged, showing pores with 5 and 6 accessory 
cells. 
Fig. 25. Cuticle x 380. One stoma with accessory cells. 
Sequoia sempervirens, 
Fig. 26. Cuticle x 135. Under surface. Part of a stomatal band. Note waved character 
of the epidermal and stomatal rows. Great length and narrowness of the midrib 
cells contrasts with epidermal cells between adjacent stomata. 
Fig. 27. Cuticle x 380. Stomatal pits surrounded by 4 or 5 accessory cells, those vertically 
orientated are generally longer than those closing in the pore horizontally and 
some show horn-like projections. 
Sequoia Tournalit. | V. 15108 b. 
Fig. 28. Cuticle x 135. Vertically orientated rows of stomata. Wide midrib. 
Fig. 29. Cuticle x 200. Showing stomatal pits more clearly. 
Fig. 30. Cuticle x 380. Showing slightly sinuate character of some of the cell-walls, 
and the presence of pits in the walls. Note the lack of sharp distinction between 
the accessory cells of the poral ring and the remaining epidermal cells. 
Sequoia Couttsiec. 
Fig. 31, Cuticle x 135. Part of a stomatal band with epidermal cells whose orientation, 
when situated between the stomatal rows, is mainly vertical, while some epi- 
dermal eells between adjacent epidermal pits show horizontal orientation. 
Fig. 32. Cuticle x 380. Five epidermal pits are shown whose orientation is mainly vertical. 
Each pit is surrounded by 4 or 5 narrow elongated accessory cells. 
Taxodium europeum, | V. 15072 a. 
Fig 35. Cuticle x 135. Part of a stomatal band. Pores bounded by 4 or sometimes 5 
accessory cells, Orientation of epidermal cells and poral axes is mainly vertical. 
Fig. 34 (see Pl. 20). Cuticle x 380. One epidermal pit shown surrounded by rosette-like 
ring of 5 accessory cells. 
Taxodium distichum. 
Fig. 35. Cuticle x 135. Showing epidermal pits surrounded by 4 or 5 accessory cells. 
Poral axes show oblique and vertical orientation. The five cells may form a 
rosette. 
Fig. 36. Cuticle x 380. Four epidermal pits with varying axial orientation, and variation 
in the grouping of the accessory cells of the poral ring. 
Glyptostrobus heterophyllus. 
Fig. 37. Cuticle x 135. Part of two stomatal bands, one from the upper and one from the 
lower surface of the leaf. Poral rings consist of 4, 5, or 6 accessory epidermal 
cells. Orientation of the poral axes variable. Epidermal cells are vertically 
orientated. 
Fig. 38. Cuticle x 540. Three poral rings with variable orientation hounded by 4, 5, and 6 
accessory cells. Note the horn-like prologation of two of the accessory cells, 
The junction of the guard cells shows as a slit, or partly open pore.
