Crocosmia corm with the tunic partly stripped to show its origin at the nodes on the corm cortex. Crocosmia corm anatomy, showing tunic, cortex of storage tissue, central medulla, and emergence of a new corm from a bud near the top. Crocosmia corm with stolons emerging through the tunic. The stolons originate at the axillary buds of the corm ...
Corm - Short, upright, hard, or fleshy stems covered with thin, dry papery leaves. Rhizome - With reduced scale-like leaves. The top can generate leafy stems while the bottom can produce roots. Iris and many grasses. Stolon - Horizontal stems that run at or just below the soil surface with nodes that root and long internodes, the ends produce ...
Corm, modified stems covered by dry scale-like leaves called a tunic, differing from true bulbs by having distinct nodes and internodes Taproot , the largest, most central, and most dominant root of some plants
Corm: A short enlarged underground storage stem, e.g. taro, crocus, gladiolus. Decumbent stem in Cucurbita maxima. Decumbent: A stem that lies flat on the ground and turns upwards at the ends. Fruticose: Stems that grow shrublike with woody like habit. Herbaceous: Non woody stems which die at the end of the growing season.
Stolons growing from nodes from a corm of Crocosmia. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. [10] In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to plants with rhizomes.
The corm produces lateral buds that give rise to side-corms (cormels, suckers) or stolons (long runners, creeping rhizomes) depending on the species and variety. Cocoyams commonly reach in excess of one metre (three feet) in height and although they are perennials, they are often grown as annuals, harvested after one season.
Erythronium grandiflorum grows from a deep bulb (or corm) which is 3 to 5 centimeters wide.Its two green leaves are wavy-edged and up to 20 centimeters long. The stalk may reach 30 centimeters tall and bears one to three showy flowers.
These series were defined by the division of the style, the corm tunic, flowering time, leaf structure, presence of a bracteole and anther colour. Mathew also introduced the concept of subspecies , including 50 in all, by giving similar but different forms subspecies status if geographically separated, resulting in about 140 distinct taxa.
