The normal leaf which is pinnately compound in nature develops in the seedling stage, but it soon falls off. This flattened or winged petiole or rachis is known as the phyllode. 4.31) the petiole or any part of the rachis becomes flattened or winged taking the shape of the leaf and turning green in colour. Out of these two leaves are normal and third gets modified into adventitious roots which help in floating over the surface of water (Fig. In case of Salvinia three leaves are present at one node. In Bignonia unguiscati the three terminal leaflets of leaf get modified into claw like hooks which help in climbing (Fig.
They are also found in Casuarina, Asparagus etc. Scale-leaves are common in parasites, saprophytes, underground stems, etc. Sometimes scale-leaves are thick and fleshy, as in/onion then their function is to store up water and food. Their function is to protect the axillary bud that they bear in their axil.
Typically these are thin, dry, stalkless, membranous structures, usually brownish in colour or sometimes colourless. In barberry the leaf itself becomes modified into a spine while the leaves of the axillary bud are normal. The leaf-apex in date-palm, dagger plant (Yucca) etc., is so modified, while in plants like prickly or Mexican poppy (Argemone), Amercian aloe (Agave), Indian aloe (Aloe), etc., spines develop on the margin as well as at the apex.
4.25) the minute leaves of the axillary bud are modified into spines. It has been hosted in in 28 locations, from Stirling to Sutherland.Leaves of certain plants become wholly or partially modified for defensive purpose into sharp, pointed structures known as spines. Since then The Mòd has run every year with the exception of wartime periods. They founded The Mòd in the same year as a way to to celebrate Gaelic literature, history, music and art. In 1891, An Comunn Gàidhealach (The Association of Gaels) was established in Oban to help preserve and develop of the Gaelic language. It draws in fluent and learner Gaelic speakers alike, with a host of other interested and curious attendees. The first half of the week is dedicated to school competitions, while the second half is for adults. It is held in a different Scottish town every year, and celebrates Scottish Gaelic’s creative heritage and traditions. The Royal National Mòd, often known simply as The Mòd, is an eight day festival of Gaelic music, art and drama. The annual festival began on Saturday with a torchlight procession through the main town, and we’re here all week soaking up the atmosphere. This week, record numbers of revellers descend on Fort William for the Royal National Mòd.
