Description
Korthalsella sp.
Figure 13
Material. Present in 5% of the shelters with dry vegetation. Shelter-006, LX5567, Shelter-007, SL 6481, Shelter-029: LX5799, LX5807, LX5803; Shelter-077, LX2552, Shelter-082, LX2450.
Remarks. Four fragments of shelter floor and two coprolite cuticles have paracytic stomata with clearly visible guard cells. The polar ends of the stomatal complexes are typically flat, while the sides curve out. The stomata are sometimes in short but distinct rows of epidermal cells, and are clearly oriented transverse to the row, while a few stomates can be perpendicular to the trend. In other areas of cuticle there are no distinct epidermal rows, and stomatal orientation is not clearly aligned. The cuticle is identified as the mistletoe Korthalsella. In reference material of extant Korthalsella, this range of stomatal distribution and orientation reflects location‒near the leaf base, the stomates and intervening epidermal cells are in clear files but become less clear away from the base. No other New Zealand Loranthaceae genera have this cuticle morphology. For example, Ileostylus micranthus, a broad-leaved mistletoe found in wetter vegetation peripheral to the study area, has randomly oriented stomatal complexes. Three species of Korthalsella currently occur in the study area (Sultan, 2014), but distinguishing between them on cuticle fragments is not attempted.
