A couple of UVIVF flowers


Recommended Posts

My botanic knowledge i too rusty to try specify these. The first one looks somewhat familiar to me, here a specimen in natural light where it was growing wildly on the side of the salad bed in the garden I was looking after:

Then indoor VIS, with light from a Niterider Lumina 900 Boost LED bike light. I am not sure why it looks more yellow here. It is likely not the same specimen, but picked at the same location:

Second plant was a domestic one growing in a flower bed, Here indoor VIS with the bike light, pretty heavy crop:

The first one with D500 and Nikon AFS 300 mm f/4 PF, all the rest D500 with 105mm f/4 AIS @ f/8-f/10 with a Nikon L39 UV filter. All UVIVF 8s exposures lighted by Convoy S2+ 365nm and Tank 007, both lights with what is likely ZBW2 filters on the front. Shot with daylight WB and warmed to 8000-1000K in CNX-D in post to dampen the blue cast.

The first one is Eruca sativa. Or some Raphanistrum, but E. sativa seems more likely.

 

The second something in the Lobelia genus.

Thanks for pointing me in the right direction, Birna. After looking them up on the wiki, I think the images I see for your second choice Raphanus raphanistrum looks most similar? (https://en.wikipedia...Wild_Radish.jpg )The ones for Eruca sativa seem to have some spines (https://en.wikipedia...uary_2008-1.jpg ) that do not show in my image, and the shape of the petals and patterns seem more like.

I still think E. sativa is the answer. However, foliage and fruits (siliqua) usually are required for identification of Cruciferae as the flowers themselves rarely suffice.

Thanks, Andy. that was certainly my motivation. But I will keep in mind to get some captures just for identification in the future.

 

I showed the images to a biology colleague and seasoned botanist who is visiting here now (faculty member long time ago) without mentioning the candidates pointed out here, and his response was: "That was Raphanus sp., radish or wild radish. Weed or crop? (Mustard family)." He got quite interested in the UVIVF image I included and I pointed him to this site.

I would have also said Raphanus because arugula/Eruca flowers tend to bunch up. But one stalk is not enough to be sure. And I haven't seen all that many Eruca plants in bloom. The Eruca seed pod does not have constrictions between the seeds like the radish/Raphinistrum seed pod.

 

If the plant grew from a stray cultivar seed from the nearby garden bed, then it could be either or something else. Cultivars can drift from the wild flower.

 

The UVIVF are so lovely!

Thanks for the comment, Andrea. Sure UVIVF is lovely both in its expression and relative simplicity.
