at the tip and margins; keel half broadly elliptic, acute, auriculate, saccate, ca. 4 × 1.75 mm including the 1 mm claw, dark red. Stamens slightly dimorphic: inner whorl of 5 with longer, slender filaments and subversatile anthers; outer whorl of 5 shorter with broader filaments and basifixed anthers; filaments all compressed and lightly cohering; anthers all 2-celled.

Seed globose (plump), red-brown with a white, continuous aril. ( Fig. 104 View FIGURE 104 ).

Affinity:— This species is closely related to D. emarginata ( Fig. 1B View FIGURE 1 ), with which it shares a similarity in general aspect, as well as details of the reproductive structures. The most obvious difference is seen in the phyllode apex, which is obtuse and emarginate in D. emarginata , but acuminate and pungent in D. daphnoides .
