Moraea tripetala

12 comments


In 2012, the powers that are out there decided that M. tripetala needed to be revised into 9 species. Since I grew mine from seed, there is no easy way of identifying which of the new species it falls into. But one way to reduce the field is by its tepals. A feature of M. tripetala is its small or missing tepals.


If you look where the 3 petals join, you will see a hair, which is the tepal. It is only about 2mm long, so it is easily missed. This lets out 5 of the new species, so it is a guess between the remaining 4.
Next is the nectar guide.


The nectar guide is the white and yellow spot that guides insects into where the pollen is located. This feature also narrows the ID down to 2 possibilities: M. grandis and M. tripetala (which has 3 variations).
Another great feature of this one are the nectar guides and its spotting.


You can see the spots better if the petal is pulled down as if a bee was going in. It is white with dark purple or black spotting, and the edge is outline in blue/purple.
So I suspect that this is Moraea grandis.
On a side note, compare the next 2 photos:


The first was taken without a flash, the second used the fill flash setting on my camera and the background becomes dark.
I really like this flower, the way it all seems to dance and twist. The seeds were started last year, so it is quick to bloom.

An interesting bit of detective work, excellent photos showing the features mentioned.

That's impressive! And what a useful tip about the use of fill flash.

beautiful plant.

You're so clever Wylie. I just like the look of it I'm afraid, it looks a bit similar to an Iris but that's only my impression. Nice looking flower in any case.

Thank you, everyone. With all the modern research tools available, some parts of the plant world are being renamed and regrouped; and it gets a little confusing.
Thorneyside: It should look like an Iris because it is in the genus Iridaceae, of which Iris is the best known. But this is different: It is winter growing and flowering, has a bulb instead of a tuber, and needs warmer temperatures than an Iris (which do poorly here). The flowers are also much smaller than an Iris, so I have them in pots which are placed at eye level on a ledge. They also like to be dry during the summer rest, so I don't have to water them.

Your photos have prompted me to be more inventive with my photos, hence I am putting into favourites to remind me.

I have been frustrated with my camera. I try to take photos, and it is all autofocus and not really designed for macro work; so I am replacing it, and hope to have even better photos.

I do like your fill in flash photo, and have been experimenting with my Canon icsus, but am now most frustrated. I am able to put on macro, and fire the flash, but although the background is deliberately out of focus, it is still bright. I think the easiest solution is to place a dark backdrop behind the subject. More reading of instructions required!

If you are too close, the fill-in becomes less effective. Pull back a little, use the fill-in, and then crop the photo.

Thank you for explaining 'plant identification.' Function, form & beauty untied in fantastic style.

Glad you liked it!
