The adult mature eels (Anguilla bicolor bicolor)from the streams of the Southwestern region of Sri Lanka migrate to the Indian Ocean along with flood waters during rainu seasons of October to December and April to June. The elvers are abundant in the Northern Bolgoda Lake from about November to about February and from about May to about August, when the salinity of the Lake Water is low. The length of the larvae ranged from about 3.2 to about 7.3 cm and their weight ranged form about 0.4 gms to about 2.1 gms. 1985-01-01T00:00:00Z Right-Left Symmetry in Shoot and Flowers of Tribulus Cissoides Tennakone, K. http://dr.lib.sjp.ac.lk/handle/123456789/509 2022-02-24T05:51:16Z 1985-01-01T00:00:00Z Right-Left Symmetry in Shoot and Flowers of Tribulus Cissoides Tennakone, K. Tribulus Cissoides has oppositely placed large and small paripinate compound leaves at the nodes alternating between right and left hand sides. The flowers arising at the axils of small leaves have clockwise(right-handed)or anticlockwise (left-handed)imbricated petals depending on whether they are on the right or the left hand sides of the stem. Thus Geometrically, the Structure at each node is the mirror image of the one above or below. It is found that the flower differentiation process favours 'left handness,' for about 53% of the flowers orginate in the left-handed leaf axils and approximately the same percentage of secondary shoots orginate in the right-handed leaf axils. 1985-01-01T00:00:00Z Mahasami Sangha Raja Institution in Sri Lanka Rohanadeera, Mendis http://dr.lib.sjp.ac.lk/handle/123456789/508 2022-02-24T05:37:32Z 1985-01-01T00:00:00Z Mahasami Sangha Raja Institution in Sri Lanka Rohanadeera, Mendis 1985-01-01T00:00:00Z
