The occurrence and frequency of stomata of leaves of Monstera deliciosa (Araceae)
By Dorothy E. Shaw     (Buy)


As revealed by impressions on celloidin strips, stomata were present on all leaf parts of Monstera deliciosa sampled, but were more abundant on some parts than on others. On pinnatifid leaves, the calculated mean numbers of stomata per mm2 were: on the lower surface interveinal laminae: 49.9; upper midribs: 27.1; upper petioles: 3.3; lower petioles: 1.8; upper interveinal laminae: 0.8; and lower midribs: 0.6. On entire leaves the corresponding figures were: 32.1, 27.4, 2.5, 3.5, 2.6, and 0 calculated mean numbers of stomata per mm2, respectively.
