Different Forms
By Ian St George


Figs 1 and 2 appear to show two forms of Caladenia chlorostyla from Scott Point, Te Paki.
There are two forms in the Wairarapa too, one of them pictured here ( B&W photo).

The Wairarapa plants have a better defined set of marginal calli, but otherwise the two appear to be
similar to the two from Te Paki. There is of course a third, that photographed by Kevin Matthews for
the cover of J102, aka C. aff chlorostyla, first separated off by Bruce Irwin.

Actually, the last has greater affinities with the small version on the left - with the bent-over dorsal
sepal of Stegostyla species, and the short tepals.  

I wonder how many forms of Thelymitra pauciflora we have in New Zealand? Jeanes considers we have
T pauciflora s.s., but which is it?

Fig.3 shows one form from the southern Hunuas; the photo in the middle that from the Wairarapa.
One from Kaitaia is photographed by Kevin Matthews and appears as Fig.16.

 

Fig 4

Fig.4 shows the column of a form I have tagged T. aff brevifolia because it looks just like the illustration
of that species in Jeanes's paper.  Fig.5 shows the column of T. intermedia Berggr., which appears to
match T. colensoi Hook. f.

 

Fig 7-9

The column illustrated in Figs.7-9 is that of a tiny, sky blue flowered form growing on a dry bank in
the southern Wairarapa, spotted by the keen eye of Pat Enright. Most were over, so we examined only
a couple of columns, but we will look a little earlier in mid-November 2007.
