Studies on Homalomeneae (Araceae) of Borneo XIII - New Species of Homalomena

Fig. 6. Homalomena galbana Baharuddin S. & P.C.Boyce. A. Leaf blade, adaxial view. Note the distinct quilting of the leaf blade between the primary lateral veins. B. Detail of synflorescence. The inflorescence in the foreground is in the early stage of fruiting, that to the left is at post anthesis, and beginning to become declinate. The open inflorescence is at pistillate anthesis, the one directly behind will be open in three or four days. Just visible is a newly emerging inflorescence, with the rostrum already conspicuously bicoloured. C. Spathe. Note that it is deeply fornicate, and that the margins are recurved. D. Inflorescence at pistillate anthesis with spathe artificially removed. Note that the interpistillar staminodes exceed the associate pistil. Note, too, that the staminodes are directed downwards, and that the lowermost ones are appressed to the stipe. E. Detail of staminate zone. The clusters of 4 stamens per flower are easily seen.
