Blog Postings

The postings will be introductions to each of my life lists. The lists themselves will appear in the side margin. I shall do some postings about particular localities and there will also be postings to provide updates every time I add a new species.
Please note that I am not qualified in any aspect of natural history - there will therefore be occasional (or, apparently, in the case of the hoverflies, a lot of) errors.

Annual Knawel


It is fairly rare nowadays for me to add a new flower to my species list. With a few exceptions anything new I see is likely to be one of a group of difficult to distinguish species (which I am too lazy to identify). There are, however, a number of species of which I do not have decent photos. Some of these are very common and have simply been ignored because I've assumed I have already taken them. This was the case with Annual Knawel (Scleranthus annuus) until Daughter-who-takes-photos asked me to identify it in her garden. Reaching up to 10cm high, it is common on dry, bare places throughout Britain and Ireland and can be an abundant garden weed. The narrow, pointed leaves are borne in opposite pairs along the stems. The flowers comprise close-knit heads of greenish white sepals with no petals and appear from May to August.

It is also known as German Moss or German Knotgrass and few of the photos on the web look like mine but I reckon I’ve identified it correctly. One that does look like mine is at Wild Plants in Netherlands and Belgium.

Welcome - comments are nearly always appreciated (the exception being those that simply advertise which don't make it past my moderation so please, don't bother).
