The paper presents structural aspects of the vegetative organs (adventitious root,
stem and leaf) of a monocot herb, native to Sri Lanka and Thailand, namely
Cryptocorynewendtii de Wit. It is a green variety of Cryptocorynewendtii, growing both
submerged and emerged in its native regions. In our country the plant is known as an
aquarium plant. The material fixation and processing was done according to the usual
protocol of the Vegetal Morphology and Anatomy Laboratory belonging to the Natural
Sciences Department of the our faculty. The adventitious root has a primary monocot
structure with small intercellular spaces. The short stem vascular system consists of
amphivasal bundles to the center and fewcollateral bundles to periphery.The petiole
exhibits epidermis with regularlly arranged cutinized cells, without intercellular spaces,
covered by a thik cuticle and poor developed stele vascular system. The leaf mesophyll is
homogenous (isobilateral) type, with small intercellular spaces and a poor developed
midrib collateral bundle with few conductive elements. The mechanical tissues almost lack.
The petiole and blade have sclerenchyma groups of cells bellow the epidermis and for the
blade to the lower epidermis.
