Whacky plants

Bird's-nest orchid Neottia nidus-avis

In a woodland, not so far from home, is the weird and wonderful bird's nest orchid (Neottia nidus-avis) - a honey-coloured, honey-smelling saprophytic plant (i.e. grows on or derives nutrition from dead/decaying organic matter).

Ooops! I used the word 'saprophyte' above, lifted from my old edition of Rose (The Widlflower Key, 1981) - but actually I'm incorrect. Mycologist's appear to be a little miffed at botanists for repeatedly getting this wrong. So let's put the record straight. Bird's nest orchid is an achlorophyllous (has no chlorophyll) myco-heterophyte (parasitic on fungi as its main carbon source) (see links below).

Another whacky plant, which I am glad to say grows in the verge down my road (despite the best efforts of the council/utilities companies to eradicate it), is the common broomrape (Orobanche minor). Broomrapes look a bit like orchids but they are not. They lack chlorophyll and are parasites on other plants.

Roger's Weeds

Cornflower Centaurea cyanus

Ahh Beeston! Yet another lazy Sunday morning at Cos Lodge with the Beeston Wildlife Group.

Did I say lazy? I meant indulgent.

Mothing, birding, ambling amidst the wildflowers and of course, chatting. There is always such an alarming amount to do!

Despite an heady overdose of anti-hayfever meds I ventured a close encounter with Roger's arable weed patch. It was in full bloom with cornflower (Centaurea cyanus) and corncockle (Agrostemma githago) putting on a summertime show.

Corncockle Agrostemma githago

Its a shame that this is such a rare sight these days. Our native arable plants have declined alarmingly in the UK in the last 60 years or so. Roger's small patch is a glimpse of how cornfields used to look.
