Further to Martin Rand's excellent definition - a good, if lengthy, explanation of plant status can be found in Chapter 3 of The New Atlas of the Flora of...
There's leaf illustrations of some, and good "botanical" descriptions of all (a lot safer than illustrations) species of Poplars, native, introduced and...
'Normal' aspen leaves are rounded, with a slight acute tip, and broad irregular serrations. Leaves on sucker shoots _can_ be generally triangular in outline,...
Elaine, American Aspen is Populus tremuloides, as you said. You can find references in Clement & Foster 'Alien Plants of the British Isles', one of the BSBI...
Hello, One definitive way of defining the Black or Water poplar Poplus nigra is that nearly all of the trees are infected by a aphid which causes a spiral gall...

Apparently the most widely distributed tree in N America, and in world terms it rates third only (amongst trees) to Populus tremula and Pinus sylvestris. It...
Populus tremuloides. As I've already told Ian, I didn't like it when I grew it. It was much noisier than our own wild Aspen, sounded as though it was always...

Hi I have been asked by a local farmer about the red clover in his fields not setting seed. He wants the red clover in his fields, which is abundant in some...

Are the fields sprayed with an insecticide which kills off the bees which might pollinate it? Shades of C. Darwin's assertions that old ladies living near a...
P. tremuloides is a very rare alien in this country (one specimen as evidence cited by Clement & Foster) and hardly in cultivation (well, what advantage does...
I am sure someone knows the correct answer but I was given Red Clover seed three years ago to sow for green manure. It grew and flowered very well for two...
The reason why it is not setting seed is highly likely to be due to lack of suitable pollinators. I'm afraid I don't know much about bumblebees, but that would...
Hello Well it was a rather stunted plant growing in the poor soil around Widewater Lagoon. Probably too high to be affected by salinity. Made me wonder what...
Clovers ,like many Legumes often rely on Symbiotic nitrogen fixing bacteria (Rhizobium spp) that live in the little ( red pigmented) nodules on the roots....

Hello, http://tinyurl.com/to22 Three common leaves of the Adur riverbank, the one on the right is likely to have been planted, but the others probably grow...
I suspected as much, and I've certainly never seen it here. I wonder if there's one in the Hillier Arboretum? I might pop down the road and see tomorrow. ... ...

Populus nigra "Plantierensis" (or var. plantierensis) is widely planted in north London and is much commoner here than the true Lombardy Poplar (Populus nigra...
Help! Did any BSBI VC Recorder using MapMate get a patch from the late Pete Selby for setting up a User Query for the above? I have it installed but have no...
Hello, I think the patches ( the ones that you can down load from MapMate) install them selves and are integrated into the system some how??? I use MapMate and...
Yes and no! I mean, it was a User Query patch from Pete Selby, not Teknicka, and no, the BSBI person replacing Pete does not know anything about it. I think...
Elaine, When you say "the BSBI person replacing Pete", do you mean me? (I'm not actually that person - that's Bob Ellis - but I am caretaking the database on...
Hi, folks, I meant just what I said - "the person" as I deliberately wanted to avoid giving a name! I cannot believe Pete gave it only to me and someone "out...
OK Elaine, that may have lost a little bit in the translation but I think we can make sense of it. Thanks for your efforts to extract it manually. All this...
