Morphology and anatomy of Hedysarum pannosum (Boiss.) Boiss. stems, leaflets and petioles. The anatomical results show that the plants have secondary growth roots, protruding stems, amphistomatic and equifacial leaves with tannin, triangular shaped petioles. E., ERTUGRUL, K., TUGAY, O., DURAL, H., Karyological studies of the genus. Lycopodium (sensu lato) into three genera: Dendrolycopodium, Spinulum, and Lycopodium (sensu stricto). The reasoning behind this division is very strong, and it is here followed. Profound differences in anatomy, morphology, reproduction, gametophyte morphology, and karyotype support this separation. The chromosome numbers of our genera.
Thoroughly revised and updated throughout, the book covers all aspects of comparative plant structure and development, arranged in a series of chapters on the stem, root, leaf, flower, seed and fruit. Internal structures are described using magnification aids from the simple hand-lens to the electron microscope.

Bog club-moss [ Lycopodium, a genus name, and - ella, diminutive] Plants creeping on wet ground. Roots emerging immediately on underside of stems. Horizontal stems on substrate surface, supine or arching. Upright shoots forming very leafy peduncles scattered along horizontal stems, 2- . Lycopodium is widely distributed in temperate, sub-arctic, and tropical climates, though those found in the tropics tend to be confined to mountainous environments. There are more than species, subspecies, and varieties of plants in this genus. Although these plants are generally abundant, there are some species that have been listed as threatened and endangered.

Lycopodium species vary in growth form and morphology. The mature aerial stems of a plant photosynthesize. They may be either non-branching or treelike in form. When mature, the aerial stems often have cones (strobili) or sporangia that produce the spores necessary for sexual reproduction.
Spores mature and are. External Morphology of Lycopodium: The herbaceous plant body is sporophytic. Usually they may have either prostrate stem with erect leafy branches or weak pendent stem (epiphytes). Stem. The stem of all the species of Lycopodium are in general weak, slender and rhizomatous.
It is usually erect (e.g., L. selage) or pendent (e.g., L. phlegmaria) in the sub-genus Urostachya and prostrate creeping in the sub-genus Rhopalostachya, which is sparsely (e.g., L. annotinum) or profusely branched (e.g., L. obscurus).

Anatomy of the stem: A transverse section of the mature stem of Lycopodium clavatum shows the following structures: The epidermis is one cell in thickness and has stomata that appear to be similar in structure to those of the leaf.
The outer walls of the epidermal cells are thick and cutinized. Introduction. With approximately 13 species, the Bryophyta compose the second most diverse phylum of land plants. Mosses share with the Marchantiophyta and Anthocerotophyta a haplodiplobiontic life cycle that marks the shift from the haploid-dominated life cycle of the algal ancestors of embryophytes to the sporophyte-dominated life cycle of vascular plants.

Gazette, Vol. LV., No. 2, 7. Lycopodium (from Greek lukos, wolf and podion, diminutive of pous, foot) is a genus of clubmosses, also known as ground pines or creeping cedars, in the family very different circumscriptions of the genus are in use.
In the Pteridophyte Phylogeny Group classification of (PPG I), Lycopodium is one of nine genera in the subfamily Lycopodioideae, and has from 9 to 15. Although Lycopodium gametophytes are rarely found in nature, enough is known about them to recognize two fundamental types, based principally upon their mode of growth and nutrition.
In some species the gametophyte becomes a small, green plant with numerous lobes, growing on the surface of the soil; the time interval between spore germination and sexual maturity of the gametophyte may be.

Pollen morphology of the genus Oxyrtopis in Turkey. Bangladesh journal of botany Lycopodium has been split into smaller, homogeneous groups on the basis of sporophyte and gametophyte morphology, chromosome number, and anatomy (BruceØllgaardWagner and Beitel ).
These genera also have different life histories and hybridization patterns that support the recognition of multiple genera (rather than a broadly defined Lycopodium). In this study, leaf anatomy and morphology of 14 species (Bellardia trixago (L.) All., Bungea trifida (Vahl) Meyer, Euphrasia pectinata Ten., Lathraea squamaria L., Lesquereuxia syriaca Boiss.
One of the major reasons for this is the discovery of additional ‘species’ after every collecting mission to centres of diversity of the genus (Vails et al., ).
The morphology, development and anatomy of Arachis presented problems to groundnut workers. The genus Lycopodium is commonly known as “Club Moss” or “Ground Pine”. It is a large genus comprising about species, growing mainly in sub-tropical and tropical forests.
Some species are distributed in arctic and temperate regions also. All the species grow in moist and shady places, rich in organic compounds and humus. Kuo J () Morphology, anatomy and histochemistry of the Australian seagrasses of the genus Posidonia König (Posidoniaceae).

Species of the genus are generally protostelic and may have actinosteles, haplosteles, or steles in which the xylem is dissected into a series of plate-like anastomosing strands (plectosteles). The leaf traces, which are small, arise from the tips of.
The present work, therefore, reports a comparative study of leaf, stem and root morphology and anatomy of S. tenuifolium and S. vaginatum to contribute to the data base for plant identification.
The principal aim of the study was to understand the structural differences between the two species, which will be helpful in elucidating taxonomical. Reproductive morphology of the lycophytes In the lycophytes, some leaves do more than merely photosynthesize.
Special leaves called sporophylls produce a sporangium on top, near the point where they attach to the stem. This is in contrast to the condition in the zosterophylls, the closest relatives of the Lycophyta; in these other plants, the sporangia are terminal on branches of the stem.Full text of "The morphology of pteridophytes; the structure of ferns and allied plants" See other formats.

The genus Amaranthus consists about 60–70 species (Costea and DeMason, ) includes many widely dispersed, economically important grain amaranths are ancient crops with increasing prospects as potential food and feed resources because of their high grain protein and starch quality and high-nitrogen, highly digestible vegetative tissues (Cai et al.
