LEAF EDGE

LEAF EDGE

Various types of leaf margins can be observed. The types of leaf margins, there is not change the general shape of leaves and some are changing the shape of the leaves.

A. Not change the general shape of leaves1. Mengutuh - average ( entire , integer ) ; fringe flat leaf like lines . example : Psidium guajava leaf edge2. Beringitan ( crenate ) ; edges of the leaves with a sharp sinus and obtuse angle . example : Marsilea   crenata leaf edge , the edge of the leaves Plectranthus ambonicus3. Berpicisan ( crenulate ) ; crenatus with smaller size and smoother . example : Lantana camara leaf edge4. Berliuk ( Sinuate ) ; sinus and angulusnya blunt - bumpy . example : daunPolyalthia edge longifolia5. Mergergaji ( Serrate ) ; sinus and a sharp angle . example : Ardisia serrata leaf edges , leaf edges clerodendron serratum6. Menggeregaji ( Serrulate ) ; serrate with a smaller size . example : daunMuntingia edge calabura7. Double sawing ( Biserrate ) ; serratus which each angulusnya have sinus and angle again . Generally seen serratus size long and short . example : Vitis leaf edge finifera8. Toothed ( Dentate ) ; sinus blunt a sharp angle . example : Macfadyena dentate leaf margins , leaf edges Isotoma longifolia9. Serrated ( denticulate ) ; dentatus more subtle . example : Primula denticulata leaf edges , leaf edges Davallia denticulata

 

B. Change the general shape of leaves1. Bercuping ( lobed , lobes ) ; circumstances fringe notched leaves are not so deep . Formed a shallow incision ( 1/4 ) .

  a. Pinnatilobed - > bercuping pinnate : daunEuphorbia pulcherima  b. Palmatilobed - > bercuping menjari : Ricinus communis leaves2  Bercangap ( Cleft , fidus / fissus ) ; situation leaves bertorehan periphery rather the ( 1/2 ) .  a. Pinnatifidus - > bercangap pinnate leaves of Tithonia diversifolia  b. Palmatifidus - > bercangap menjari : Carica papaya leaves3. Share ( Parted , partitus ) ; circumstances bertorehan leaves the periphery ( 3/4 ) .  a. Pinnatipartitus - > share pinnate leaves of Artocarpus communis  b . Palmatipartitus - > share menjari : leaves of Manihot esculenta4 . Indented ( Sect ) ; circumstances periphery leaves the bertorehan very basic approach .  a. Pinnatisect - > incised pinnate  b. Palmatisect - > indented menjari  c. Bipinnatisect : Jathropa leaves multifida5. Berkelar ( incised ) ; circumstances bertorehan into the periphery leaves irregularly .6. Toothed ; circumstances bertorehan fringe leaves very deep and irregular7. Melira ( Lyrate ) ; fringe leaves membiola but with several basins on both sides of the base . example : Ficus lyrata leaves , Gynura divaricata leaf8. Runcinate ; fringe leaves as melira but a notch . example : daunTaraxacum officinale

C. Other leaf edge1 . Berkelijak ( Ciliate ) ; circumstances feathering edges filled evenly as straight eyelashes .2 . Billow ( Undulate ) ; fringe leaves uneven but alternately hollowed or flat and irregular mencembung . example : Anthurium leaf plowmanii3 . Terlengkung entry ( incurved ) ; leaves the edges curved inwards or above .4 . Rolled in ( involute ) ; circumstances outer periphery side of the leaves curled inwards ( adaksial ) .5 . Terlengkung behind ( ReCurved ) ; circumstances terlengkung leaves fringe outwards or down .6 . Rolled back ( Revolute ) ; circumstances terlengkung leaves fringe outwards ( abaksial ) .7 . Pole ( Terrete ) ; leaf shape like a slim tube with a length exceeding ratio ( 1:12). example : the leaves of Allium fistulosum - > leek8 . Crimp ( Crispate ) ; situation leaves the edge of the lobe - lobe bersumbingan distorted or twisted in some areas . example : leaf Coleous sp9 . Beronakan ( Aculeate ) ; circumstances leaf -covered suburb thistles ( prickle ) .10 . Torn ( Lacerate ) ; circumstances such fringe leaves torn or cut off deep .11 . Berjelabir ( Laciniate ) ; circumstances such as leaves fringe cut up into rows of ribbons
