පඳුරු හාල්දණ්ඩා[Paduru Haaldanda]/Boulenger’s Bronze-back (Dendrelaphis bifrenalis)

Diurnal and non-venomous snake recorded from  wet and intermediate zones of lowlands to mid hills. However there are references of finding it from Mullaitivu, Vavuniya and Trincomalee of northern dry zone*. Arboreal and feeds on frogs, geckos, skinks and agamid lizards. Sometimes descends to the ground and it is said that when moving on the ground it has a habit of keeping its head and part of fore body erect(Snakes of Sri Lanka A coloured atlas – Anslem de silva & jayantha Jinasena - 2009). This picture of Boulenger’s bronze-back devouring probably a Spotted tree frog was taken in a shrub jungle of Ambagaspitiya of Gampaha district.

* Though Anslem de Silva (Snakes of Sri Lanka A coloured atlas – Anslem de silva & jayantha Jinasena - 2009) has given Wall (1921) as the reference for its distribution in Mulativu and Vavuniya there is not such a mentioning in Frank Wall’s Snakes of Ceylon(1921) page 218 where distribution of Dendrelaphis bifrenalis only includes Punagalla, Yatiyantota, Balangoda and Galle. 

රත් කොබෝලීල[Rat-koboleela]/Purple orchid tree (Bauhinia purpurea)

Macmillan in 1910 suggested Bauhinia purpurea as a flowering tree suitable for the gardening in low or median elevations due to its “very showy large flowers of a pink shade merging into purple” (Tropical planting and Gardening with special reference to Ceylon - page 80).  It is a native plant of either Southeast Asia (According to the Revised handbook to the Flora of Ceylon Vol 7) or India (According to the Illustrated field guide to the flowers of Sri Lanka J. &J. de Vlas 2008) introduced and widely cultivating in Sri Lankan home gardens. Still it is not naturalized in Sri Lanka.
