(2008) focused his attention on morphology of spore and anatomical characteristics in addition to other features. Vida (1974) has undertaken a detailed cytological analysis of C. fragilis complex in Europe where possibility of somatic polyploidization is reported. During the spore study of Cystopteris, Blasdell (1963) has observed that with the increase in ploidy level of a species there is also an increase in the spore size and has further pointed that the average spore size of a plant within the genus can indicate its ploidy level with accuracy. From the present observations also both the forma studied are tetrapoids but show variations in spore size. So it is evident that Figure 1: Cystopteris fragilis f. kashmiriensis different ploidy levels of a genus can not be the reason for difference in the spore size but a species with same chromosome number growing in two different habitats can also exhibit difference in the spore size. In dermal appendages of Cystopteris the apical cell may or may not be glandular. This character is useful in distinguishing different species of the genus. In fact, Indian species of Cystopteris can be distinguished on the basis of shape, colour and margin of the rhizome scale. Scales of C. fragilis are ovate, lanceolate, yellowish brown with acuminate apex ending in a glandular cell, margin entire as also reported presently for C. fragilis f. fragilis but the dermal appendages of C. himalayensis studied during present investigation revealed certain differences to these characters. These are appendiculate with 1-2 pairs of basal appendages and upper half of the scale is yellowish brown with thick walled cells while as rest of the cells are yellowish and thin walled, apex without a glandular cell. www.ijsrp.org International Journal of Scientific and Research Publications, Volume 2, Issue 4, April 2012 3 ISSN 2250-3153 Figure 2: Cystopteris fragilis f. fragillis Figure 4: Cystopteris fragilis f. kashmiriensis Figure 5: Chromosome number Figure 3: Cystopteris fragilis f fragilis Figure 6: Spore of Cystopteris fragilis f. kashmiriensis www.ijsrp.org International Journal of Scientific and Research Publications, Volume 2, Issue 4, April 2012 4 ISSN 2250-3153 Type: India, Jammu and Kashmir, Kashmir (KASH. 14483).

Comprising over 2500 species, the composition and particularly the relationships among the major clades of this group have historically been contentious and defied phylogenetic resolution until very recently.

Abstract The eupolypods II ferns represent a classic case of evolutionary radiation and, simultaneously, exhibit high substitution rate hetero- geneity. These factors have been proposed to contribute to the contentious resolutions among clades within this fern group in multilocus phylogenetic studies. We investigated the deep phylogenetic relationships of eupolypod II ferns by sampling all major families and using 40 plastid genomes, or plastomes, of which 33 were newly sequenced with next-generation sequencing tech- nology. We performed model-based analyses to evaluate the diversity of molecular evolutionary rates for these ferns.

  • The Marattiales and Vegetative Features of the Polypodiids We Now
    VI. Ferns I: The Marattiales and Vegetative Features of the Polypodiids We now take up the ferns, order Marattiales - a group of large tropical ferns with primitive features - and subclass Polypodiidae, the leptosporangiate ferns. (See the PPG phylogeny on page 48a: Susan, Dave, and Michael, are authors.) Members of these two groups are spore-dispersed vascular plants with siphonosteles and megaphylls. A. Marattiales, an Order of Eusporangiate Ferns The Marattiales have a well-documented history. They first appear as tree ferns in the coal swamps right in there with Lepidodendron and Calamites. (They will feature in your second critical reading and writing assignment in this capacity!) The living species are prominent in some hot forests, both in tropical America and tropical Asia. They are very like the leptosporangiate ferns (Polypodiids), but they differ in having the common, primitive, thick-walled sporangium, the eusporangium, and in having a distinctive stele and root structure. 1. Living Plants Go with your TA to the greenhouse to view the potted Angiopteris. The largest of the Marattiales, mature Angiopteris plants bear fronds up to 30 feet in length! a.These plants, like all ferns, have megaphylls. These megaphylls are divided into leaflets called pinnae, which are often divided even further. The feather-like design of these leaves is common among the ferns, suggesting that ferns have some sort of narrow definition to the kinds of leaf design they can evolve. b. The leaflets are borne on stem-like axes called rachises, which, as you can see, have swollen bases on some of the plants in the lab.

  • The Gametophyte of <Emphasis Type="Italic">Cystopteris Fragilis
    THE GAMETOPHYTE OF CYSTOPTERIS FRAGILIS BY SURJIT KAUR (Pteridology Laboratory, National Botanic Gardens, Lucknow) Received May 6, 1963 (Communicated by Dr. V. Purl, F.A.~C.) 1NTRODUCTION Cystopteris is a small cosmopolitan terrestrial genus of Athyrioid ferns, typified by C. fragilis (L.) Bernh. Eighteen species are included.under the genus by Christensen (1906-34), but according to most pteridologists (Christensen, 1938; Copeland, 1947; Holttum, 1954), many of these species may well be transferred to Athyrium. Recently Blasdell (1963) has published a detailed taxonomic account of the genus based on material from North America and East Asia including herbarium material from various herbaria. He has recognized ten species with a few varieties. The present study deals with the morphology of the spore and prothallus of C. fragilis. Spores for the present study were obtained through the courtesy of Dr. A. Lawalree from Belgium. Spore morphology is based on acetolysed preparations mounted in glycerine jelly (Erdtman, 1952). Prothallial morphology is based entirely on cultures raised on nutrient agar medium maintained at a temperature of 24 4-2 ° C. and a light intensity of 600 ft.-c. (Nayar, 1962). SPORES The spores of C. fragilis (Figs. 1, 2) are monolete (bilateral) of plano- convex, with dark brown, spinate exine (the spines are deep reddish-brown, ca. 6/~ long and with broad base and tapering apex). Surface of the exine between the spines is granulate. The laesura is tenuimarginate. The spores measure on an average 29 × 43 × 28 tz (P x E1 × E2, exclusive of spines). Blasdell (1963) describes two types of spores in this species : one with spines and the other with smooth exine on which is superimposed a layer which has given it a rugose appearance.
