Knots of C. citratus leaves sold at a supermarket in the Philippines Ready-to-use bundles of lemon grass, galangal, kaffir lime leaves, and, for chicken tom yam, also turmeric, are sold at Thai markets. Cymbopogon citratus is abundant in the Philippines and Indonesia where it is known as tanglad or sereh, respectively.
Within these the major veins function as the support and distribution network for leaves and are correlated with leaf shape. For instance, the parallel venation found in most monocots correlates with their elongated leaf shape and wide leaf base, while reticulate venation is seen in simple entire leaves, while digitate leaves typically have ...
Leaf venation is of the striate type, mainly arcuate-striate or longitudinally striate (parallel), less often palmate-striate or pinnate-striate with the leaf veins emerging at the leaf base and then running together at the apices. There is usually only one leaf per node because the leaf base encompasses more than half the circumference. [31]
The "trunk" continues to expand with age. The largest known is 9 ft 1 in (2.77 m) in diameter (8.7 m (29 ft) in circumference). [12] Because Welwitschia only produces a single pair of foliage leaves, the plant was thought by some to be neotenic, consisting essentially of a "giant seedling." However, research showed that its anatomy is not ...
The leaves are alternate and are a shiny dark green on top and light brown on the bottom. They are simple leaf types with pinnate venation. The leaves are ovate and range in length from 3 to 11 cm (1.2 to 4.3 in). The breadth of the leaves ranges from 2 to 5 cm (0.79 to 1.97 in). The leaves are evergreen so they are present year round.
The rhizome is creeping and the fronds appear to have random placement, originating at various points. The rhizome appears reddish-brown, and has a sweet licorice flavor. Since it is a fern, P. glycyrrhiza reproduces by spores; the spores form in two rows of sori, which look like large spots on the undersides of the leaves. The sori range in ...
Shape, margin and venation. Leaf Parts: – A complete leaf is composed of a blade, petiole, and stipules, but in many plants one or more might be lacking or highly modified. Blade – see lamina. Lamina – the flat and laterally-expanded portion of a leaf blade. Leaflet – a separate blade, among others, of a compound leaf
Members of this family can be herbaceous to "woody" vines. They grow from their rhizomes and are often armed with prickles on the stems and/or leaves. Leaves are alternate and simple; and entire to spinose-serrate. Some members of this family have coriaceous (leathery) leaves. Venation of the leaves may be palmate to reticulate.
