Example text

The individual binate units are then variously arranged in pseudopanicles or heads. In the woody genera, individual rhipidia never have more than one flower (Figures 1A, 2), thus the binate unit usually consists of a flower pair, or in some species of Nivenia just one flower, whereas in related genera the rhipidia usually have more than one flower. The basic rhipidium of Iridaceae consists of a pair of large, opposed herbaceous bracts, traditionally called spathes, that enclose a monochasial cyme of pedicellate (or sessile) flowers.

The anastomoses of the bands in the woody genera appear to be a step in the evolution of the base-plate-type thickening and were so interpreted by Manning and Goldblatt (1990) and are accordingly seen here as a shared specialization for the woody genera and Patersonia. Pollen grains in Iridaceae are primitively monosulcate and tectate-columellate with a reticulate surface patterning (Schulze, 1971; Goldblatt, 1990). This is also the basal pattern in the Nivenioideae. Among the woody genera the pollen grains of Witsenia stand out in having supratectal gemmae (Schulze, 1971; Goldblatt and Manning, 1989).

Stokoei, pale yellow in K. flava, but hardly different from the foliage leaves in color and size in K. partita (Plates 1012). In Nivenia the most common inflorescence is a compound pseudopanicle. The compressed peduncle branches repeatedly but the ultimate branches bear the flowers at about the same level in a more or less corymbose arrangement (Figure 1A). In N. corymbosa, N. dispar, N. concinna, N. stokoei, and N. levynsiae the binate rhipidia typically contain only one flower (rarely two in N.
