Rhubarb Triangle

Only slightly less exciting than the Bermuda Triangle, and with marginally less planes and boats disappearing, my little patch of the Rhubarb Triangle still continues to turn up botanical interest. 

The rhubarb fields are perhaps one of the few places shoddy is still used, and I live in hope of unusual weeds. But I suspect most shoddy is of British origin these days, so that is unlikely. However, a relict of former days and still doing well is White Rocket (Diplotaxis erucoides). It is not a common plant, except perhaps in Lincolnshire, but it may be overlooked elsewhere in south Leeds and Wakefield. One to look out for at this time of year.

A group of plants that has been interesting me recently are the Sell & Murrell segregates of Fat-hen (Chenopodium album agg.). These deserve a specific post, but one of the distinctive ones that seems to have merit is Druce's Fat-hen (Chenopodium drucei). A relatively tall species with ovate lower leaves and long lanceolate upper leaves. The shape of the inflorescence is also distinctive,

A few fumitories are still flowering, and this one is a subspecies of Common Fumitory (Fumaria officinalis subsp. wirtgenii var. wirtgenii). Please someone coin it a specific common name!

Believe it or not, this one is different (too many flowers) and is Fumaria officinalis subsp. officinalis var. elegans.

Not particularly notable, but surprising to see in the corner of an arable field was Russian-vine (Fallopia baldschuanica).

A pavement crack in the village on the way home ended the day well by providing Cape-jewel (Nemesia strumosa), one of the less common escapes from bedding schemes. This looks to be only the third record for VC63.

Patch Botanising

The weather has been pretty ropy recently for botanising far from home, so I have been making use of gaps in the rain to get out on my local patch. The concept of a local patch is one well known to birders, and I think its something more botanists should embrace. Still the urge to jump in the car occasionally, in favour of developing a deeper sense of place. As a VCR its amazing how many records I receive for the same honeypot locations over and over again. One group will visit one year, another the next, another the next and before you know it the first group is visiting again. There are of course benefits from this, who doesn't want to visit nice sites, it keeps the records up to date, and the combined data is potentially worth more than the sum of its parts. But at the same time there is a big wide world out there, much of it is comparatively poorly botanised, and there are still some exceptional sites and plant populations waiting to be found.

Quite often the areas most poorly known are those on our own doorsteps. And yet these are the very locations we have the luxury of getting to know intimately, through the seasons and across the years. My local patch encompasses anywhere I can readily walk to from home, so allows for a variety of circular routes and diversions over a two to four hour period. It takes in the village, two VCs (63 & 64), rivers and waste ground, arable and woodland, post-industrial sites and ancient meadows. But a lot of bog standard suburban and rural habitats. So I am always amazed that there are still new things to find five years on. A slight difference in date or direction, and the familiar is thrown into new light and something new catches the eye. The more you walk a route the more you see, the background quite literally bleeds into the foreground as the eye detects increasing detail and the brain perceives even greater subtleties in shade and form.

Here are some recent highlights from my local patch. A bit heavy on the non-natives, but to everything there is a season ... (turn, turn turn, you know the rest!). I would be keen to receive news from the local patches of others to help build up knowledge of all those overlooked little corners where the mundane mingles with the unexpected.

This year seems to be the year of Greater Duckweed (Spirodela polyrhiza), a great rarity in VC64. It has come out of nowhere, with Mike Wilcox finding it along kilometres of the Leeds & Liverpool Canal upstream of Leeds, while I have found it on the Aire & Calder Navigation in Woodlesford with abundant Fat Duckeed (Lemna gibba).

An area where earth had been moved earlier in the year by Rothwell Football Club has rewarded me with both (not so)Common Ramping-fumitory (Fumaria muralis) and the quirky (but otherwise past its best) rusty orange fruiting spikes of Quinoa (Chenopodium quinoa).

Down at St Aidan's there were a few fruiting plants of the VC64 rarity Nodding Bur-Marigold (Bidens cernua var. cernua).

While obscure corners of Rothwell Country Park have rewarded me with Argentinean Vervain (Verbena bonariensis), Japanese Anemone (Anemone x hybrida 'Honorine Jobert'), Japanese Quince (Chaenomeles japonica), and somehow, and showing the tenacity of plants, a yellow-flowered Hybrid Tea Rose (Rosa cultivar) growing out of an old spoil heap.

Elsewhere the stuff of nightmares. Floating Pennywort (Hydrocotyle ranunculoides) in the Navigation. In theory finding this plant, while still so tenuously established, is great as it affords the opportunity for a rapid response to protect the canal and river from further spread. Unfortunately this does not account for the ineptitude of the Canals and Rivers Trust, which has not to date lived up to its self-proclaimed role as "protector" and "custodian" of England's waterways. This despite having been informed in July (photo late September) and having direct management control over this location.

Less troublesome but widely planted and naturalised in the local area are Swedish Whitebeam (Sorbus intermedia) and Mougeot's Whitebeam (Sorbus mougeotii). Note the greater number and closer arrangement of the leaf veins of the latter.

And of course I always have one eye open for the infraspecifics. I'm not sure if I am just noticing it more now that I know it exists, or if it is genuinely spreading, but I do have a soft spot for this variety of Prickly Sowthistle (Sonchus asper subsp. asper var. integrifolius). This time at Swillington Park.

Here's to what the next season has to offer. Happy hunting.
