Thanks Lee and Peter. Andrew says he thinks his 
plant is a Trimezia, but isn't sure which one so 
I'll take it off the wiki page tomorrow. Mauro's 
photo of N. longifolia is certainly different and 
more like the description of that species below.

I have the Innes book but I don't usually think 
of it for current taxonomy since it was published 
in 1985. But without good sources about South 
American irids it is a help because at least it 
has descriptions of plants as they were known at 
that time. There isn't a key and they don't 
always include the same things in the 
descriptions which makes comparing a bit of a challenge.

So here are the descriptions condensed a bit from Innes:
Neomarica longifolia-
Plants to 60 cm. Leaves bluish-green, flat, 
leathery, broad, to 30 cm...Stem erect, stiff, 
wiry, to 60cm..Flowers lemon-yellow-about 5 cm. 
diam. Segments obovate-the outer with transverse 
bars of purplish-brown on the claw; inner 
segments with brownish or beige tips, spreading. 
Style 1.5c,. Flowering July to Sep.

Trimezia martiniclensis (that is how it is 
spelled in the Innes book), syn. of Iris 
martinicensis so probably it's a spelling error-
Plants 20 to 40 cm. Leaves narrow, flattened, 
slender, distichous, about 30 cm. Stem erect, 
terete, glabrous. Stem with several flowers in 
succession, each about 2-2.5 cm. diam. Flowers 
bright yellow. Segments-the outer erect, or 
incurved, oblong, about 2cm, yellow with brown 
mark at base, sometimes tinged greyish-blue; 
inner segments smaller, folded inwards, yellowish 
or brownish yellow. Flowering all the year round. 
Naturalised in many parts of the world

Trimezia steyermarkii
plants to about 60 cm tall. Rhizome-like corm 
about about 4cm. Leaves ensiform, thin textured 
with prominent mid-rib. Stem with terminal 
spathes, several flowered, herbaceous, thin 
textured. Ovary glabrous, clavate, to 1 cm. 
Flowers yellow with purple and brownish-purple 
bands, about 3c . Flowering about August and 
September. Closely allied to T. martinicensis

Too bad Mauro doesn't have a photo of both of 
these Trimezias on his web site so we could 
compare them. So what do those of you who are 
good at deciphering botanical descriptions think. 
Is what Andrew is growing and I grew Patty Allen 
sent me as T. martinicensis really T. steyermarkii?

Do a Google search for Neomarica longifolia 
and/or Trimezia martinicensis and you'll find 
photos of what looks like the same plant and may 
be neither. It looks like people may be growing 
the same thing under different names in spite of the lack of synonyms.

Any one have access to this resource Andrew thinks might be helpful:
