Soosairaj, sp. nov. can be distinguished from B. suffruticosa (Delile) Fenzlas a nonaromatic erect herb (vs aromatic shrub), with glabrous leaves and stipules (vs pubescent), a mucronate apex of the petals (vs obtuse) and a vesicular seed surface (vs smooth). The morphology of B. cuddalorensis S. Soosairaj, sp. nov. closely resembles B. ammannioides Roxb. but can be differentiated by having glabrous leaves and stipules (vs pubescent), a mucronate apex of the petals (vs obtuse), 6-10 flowers per node (vs c. 30 flowers per node) and seed surface vesicular (vs reticulate) (Table 1).</p><p>TYPE MATERIAL. — India • 2 specimens; Tamil Nadu, Cuddalore district, Veppur, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=78.96609&amp;materialsCitation.latitude=11.467978" title="Search Plazi for locations around (long 78.96609/lat 11.467978)">Lathur Forest</a>; 11°28’04.72”N, 78°57’57.93”E; alt. c. 90 m; 26.I.2023; S.

It is found growing in association with Ammania verticillata (Ard.) Lam., Vahlia digyna (Retz) Kuntze, Epaltes divaricata (L.) Cass., Hoppea dichotoma Willd., Exacum pedunculatum L., Lindernia dubia (L.) Pennell and Rotala verticillaris L.
