Title Epidermal structure and ontogeny of stomata in some Centrospermae
Source Feddes Repertorium
Abstract The epidermal structure, anatomy and ontogeny of stomata in 25 spp. [Glinus oppositifolius, Mollugo spp., Sesuvium portulacastrum, Trianthema spp., Aerua spp., Celosia spp. Nothosaerua brachiata, Echinocactus spp., Epiphyllum truncatum, Opuntia dillenii, Pereskia grandiflora, Atriplex stocksii, Beta vulgaris, Chenopodium spp., Salsola foetida, Suaeda spp., Salicornia brachiata and Talinum calycinum] of the Centrospermae are presented. The epidermal cells are polygonal, isodiametric or elongated in various directions with thick, either straight or arched or sinuous anticlinical walls. Simple uniseriate trichomes with terminal capitate cell, capitate eglandular, unicellular spiny, cylindrical and simple unicellular trichomes are noticed. Anomocytic, paracytic, diacytic, anisocytic, transitional type between paracytic and diacytic, and stoma with a single subsidiary cell are the stomatal types observed. Abnormalities such as single guard cells, degeneration of guard cells, arrested developments and cytoplasmic connections between adjacent stomata are observed. The ontogeny of anomocytic stomata is perigenous, that of stoma with a single subsidiary cell is mesogenous, of paracytic, diacytic and transitional between paracytic and diacytic stomata is either mesogenous or mesoperigenous, while that of anisocytic stomata is mesoperigenous. Diacytic and paracytic stomata are structurally similar but have dissimilar ontogeny. Division of the Centrospermae into 4 suborders is justified.
