Tephrosia encoptosperma

T. subtriflora is very variable in Somalia and includes some rather distinct forms of uncertain status. The typical form is the most widespread and is ± short-lived with several, fairly short and wide leaflets, small pale flowers, and an indumentum of ± spreading hairs. On coastal dunes in S Somalia there are prostrate forms with large purple flowers and comparatively broad leaflets (e.g. Thulin & Warfa 4522). The types of T. graminifolia and T. sulphurea represent a distinctly perennial form with few, long, narrow leaflets, an appressed indumentum, and fairly large flowers. This is fairly common in C and S Somalia, particularly in bushland on sand. Similar plants are also known from Kenya. A perennial form with digitately to pinnately 3-foliolate leaves, leaflets up to 90 mm long, and most flowers arranged in pseudoracemes in C1 and S2 (Wieland 4314, 4496, Thulin & Abdi Dahir 6528, Thulin, Hedrén & Abdi Dahir 7383, 7388 and 7456) is included here only tentatively. A similar plant with 1-foliolate leaves is represented by Thulin & Warfa 4624 and Thulin & Abdi Dahir 6466 from C2.
