Cassia abbreviata subsp. beareana flowers

The inflorescences of Cassia abbreviata subsp. beareana grow on long peduncles as large, loose sprays or racemes at stem-tips. The fragrant inflorescences can measure 20 cm by 15 cm.

The floral parts of the bisexual flowers occur in fives, the green calyx tube short and the pedicel slender. The flower is laterally symmetrical or zygomorphic. The spreading petals are large, flower diameter about 4,5 cm.

There are ten stamens, not all equal as three are much longer and curved, the short ones straight. Different pollinators or ones differing in floral visit behaviour can all be waylaid by flowers endowed in this way. The superior ovary ends in a single, curved, stigma-tipped style, the stigma truncate.

The flowers are usually present before the leaves of the tree that is deciduous. Flowering happens in spring, more in the first half of it.

The flowers resemble some of the Senna tree flowers but those can be recognised by conspicuous glands on the leaf rachises, lacking in Cassia (Coates Palgrave, 2002; Schmidt, et al, 2002; Van Wyk and Van Wyk, 1997; iNaturalist; https://treesa.org).
