Studies on the Stomata of Some Rubiaceae
Journal Title: Academic Research International - Year 2015, Vol 6, Issue 4
Abstract
Twelve taxa comprising six herbs, four shrubs and two liane were documented with descriptions for the nature of stomata. The epidermal cells are generally arched as found in 9 taxa with the remaining 3 taxa waxy. Anomocytic, paracytic and mixedanomocytic and paracytic stomata were observed with preponderance of paracytic type- 8 taxa, anomocytic-1 and mixed anomocytic–paracytic- 3 taxa. Stomata size ranges from 20.16µm± 0.22 x 13.44µm± 0.21 in Mussaenda chippii to 43.24µm± 0.29 x 31.92µm± 0.58 in Borreria ocymoides. Stomata index values vary from 5.70% in Diodia scandens to 25% in Oldenladia affinis.
