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: Harvard Papers in Botany 14(2) 97-99 (2009), Seven New Combinations in the Genus Neomarica (Trimezieae-Iridaceae) - André Dos Santos Bragança Gil, Volker Bittrich, and Maria Do Carmo E.
