Senna auriculata
Senna auriculata is a legume tree in the subfamily Caesalpinioideae. It is commonly known by its local names ranawara or avaram, or the English version Avaram Senna.
It occurs in the dry regions of India and Sri Lanka. It is common along the sea coast and the dry zone in Sri Lanka.
Avaram Senna is a much branched shrub with smooth cinnamon brown bark and closely pubescent brachlets.
The leaves are alternate, stipulate, paripinnate compound, very numerous, closely placed, rachis 8.8-12.5 cm long, narrowly furrowed, slender, pubescent, with an erect linear gland between the leaflets of each pair, leaflets 16-24, very shortly stalked 2-2.5 cm long 1-1.3 cm broad, slightly overlapping, oval oblong, obtuse, at both ends, mucronate, glabrous or minutely downy, dull green, paler beneath, stipules very large, reniform-rotund, produced at base on side of next petiole into a filliform point and persistent.
Its flowers are irregular, bisexual, bright yellow and large (nearly 5 cm across), the pedicels glabrous and 2.5 cm long. The racemes are few-flowered, short, erect, crowded in axils of upper leaves so as to form a large terminal inflorescence (leaves except stipules are suppressed at the upper nodes). The 5 sepals are distinct, imbricate, glabrous, concave, membranous and unequal, with the two outer ones much larger than the inner ones. The petals also number 5, are free, imbricate, crisped along the margin, bright yellow veined with orange. The anthers number 10[verification needed] and are separate, with the three upper stamens barren; the ovary is superior, unilocular, with marginal ovules.
The fruit is a short legume, 7.5-11 cm long, 1.5 cm broad, oblong, obtuse, tipped with long style base, flat, thin, papery, undulately crimpled, pilose, pale brown. 12-20 seeds per fruit are carried each in its separate cavity.
