I missed it!

Grass vetchling with pods.

I’ve just found one of my favourite plants on campus – and I missed it in flower! I’ve seen it on campus before during the Bioblitz in 2013. It was flowering amongst what appeared to be a planted wild flower mix behind Mackinder Hall. Now it’s turned up, self-seeded, in wasteground near the Agriculture Building on the other side of campus.

Grass vetchling (Lathyrus nissolia) is a member of the pea family (Fabaceae) but, until it flowers, the plant looks just like a grass. It has long, linear ‘leaves’ and tall stems, but it’s flowers are bright pink, miniature pea flowers. These are borne singly or in pairs. Later long, fine, typically pea-like pods develop.

 

Base of plant. How grass-like is that?

There are five well-developed plants on the patch of wasteground. How did they get there? Did the seeds arrive in bird droppings? The seeds seem rather large to travel that way. They’re 3 mm long even in unripe pods. Did someone throw compost away here? Or could they have arrived on mowing equipment that had previously been used behind Mackinder Hall?

Whiteknights Moths

Lime Hawkmoth

Lime Hawkmoth

Continuing the overhaul of our campus species lists, moths are the next group to have received a thorough treatment. More than 2400 species of moth have been recorded in the UK, so the current total of 113 for Whiteknights campus represents only 5% of the national fauna. However, the bulk of these records date back no further than last year’s Bioblitz, and the majority are from a single light-trapping location. It’s therefore fair to say that our list represents a decent start and covers a spectacular diversity of species. A quick flick through the image gallery should certainly be enough to dispel any notion that moths are all small, brown and boring.

Small toadflax

Small toadflax

The Small toadflax (Chaenorhinum minus) has been found on campus.

In fact it’s been here for a while according to the greenhouse staff who see it come up every year in the gravel strip between the cold frames and the greenhouses.

It’s an annual so the plants set seed each summer. These germinate in the spring to produce a new crop of tiny, pale snapdragon flowers. The plants are typically only 5 to 15 cm tall with tiny linear leaves so they are easy to miss.

Harlequin Ladybirds on Whiteknights Campus

Harlequin ladybirds arrived in the UK in 2004 and are spreading rapidly.  This week I have noticed many mating pairs on campus – some in the traditional red-with-black-spots colours but also many that are predominantly black.  The UK Ladybird Survey is tracking the spread of this invasive species.  The Harlequin is bigger than many of our native ladybird species and tends to out-compete them.

Campus 21st May 2014

Sometimes my walk in to work is so amazing I just have to take some photos.  Today I wanted to check on the progress with the developing reed beds that will promote greater biodiversity around Whiteknights lake.  The blue sky and nearly windless atmosphere is not good for my hayfever but I’m sure it is good for my wellbeing, and offers a real chance to prepare my mind for a busy day at work.

Mousetail – not extinct on campus

Mousetail

Mousetail

Mousetail (Myosurus minimus) was reported in the Flora of Whiteknights Park as ‘believed to be extinct’. It had been previously recorded ‘in disturbed soil and gravel outside PSL’ (the Harborne Building). The area where it had been known had been covered in mulch.

A large population of Mousetail has appeared on horticultural land behind the furthest greenhouses beside the Harborne Building. Some of the plants are still in flower but most are developing their mousetail-shaped fruiting spikes.

Parts of this area are due to be affected by future building works. The greenhouse staff have kindly offered to consider having some of the plants moved to a safer location so that they have a chance to set seed and to persist on campus.
