10 types of normal stomata along with 4 subtypes, one intermediate type between stephanocytic and hemiparacytic and some abnormal stomatal structures both in the vegetative and floral organs of Canella winterena (L.) Geartn. (Canellaceae)

“在冬蔷薇植物（Canella winterena (L.) Geartn. (Canellaceae)）的叶绿素体器官和花部器官中，有10种常规气孔类型和4种亚型，其中有一种介于棒状气孔和半背曲气孔之间的中间类型，以及一些异常的气孔结构。”

“10 tipos de estômatos normais juntamente com 4 subtipos, um tipo intermediário entre o estômatos estefanocíticos e hemiparacíticos, e algumas estruturas estomáticas anormais tanto nos órgãos vegetativos quanto nos órgãos florais de Canella winterena (L.) Geartn. (Canellaceae).”

Abstract

The presence of 10 types of normal stomata along with 4 subtypes, one intermediate type between stephanocytic and hemiparacytic and some abnormal stomatal structures both in the vegetative and floral organs of Canella winterena (L.) Geartn. (Canellaceae) is reported here. The epidermal cells are polygonal, isodiametric in surface view with straight anticlinal walls. The stomata are amphibrachyparacytic, anomocytic, anisocytic, brachyparacytic, brachyparatetracytic, cyclocytic, hemiparacytic, laterocytic, holoparacytic, stephanocytic, one intermediate type between stephanocytic and hemiparacytic, etc. Abnormalities like contiguous stomata, different types of twin stomata and cytoplasmic bridge between adjacent stomata, stomata with single guard cell, single guard cell with pore juxtaposed with normal stoma are also found. The presence of giant stomata is a significant finding. (© 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

The epidermal cells are polygonal, isodiametric in surface view with straight anticlinal walls.
The stomata are amphibrachyparacytic, anomocytic, anisocytic, brachyparacytic, brachyparatetracytic, cyclocytic, hemiparacytic, laterocytic, holoparacytic, stephanocytic, one intermediate type between stephanocytic and hemiparacytic, etc.
