Fine structure of a flower Cochliostema odoratissimum 2
Flowers: staminodes 3, anterior, medial one vestigial, lateral ones densely bearded, lacking an anther;
stamens 3, posterior, filaments fused, with a dense dorsal tuft of yellow hairs, anthers enclosed within
a columnlike structure composed of broadly expanded connectives of the lateral stamens, the connectives
each terminally drawn out into a narrow tube with a terminal pore; seeds exarillate, biseriate, hilum linear,
embryotega dorsal (R. B. Faden).
