Two nice finds

 During the recent warm spell, I have been walking on the Etteridge and Phones tracks, doing some botanical recording. (Phones and Etteridge are two Estates south of Newtonmore.)

 Most of what I found was fairly common but I was surprised to find this plant by the side of the Etteridge track:

Hemp-Agrimony
It is Hemp-agrimony (Eupatorium cannabinum), which I have never seen round here before. The nearest recorded plants are in Nairn and Pitlochry. It's always a buzz to find something new to the area!

The leaves are similar to Hemp (Cannabis sativa) leaves, hence the name.

The second day I walked in from the Phones end, and saw these strange yellow tuning-fork structures amongst the heather:

The next photo gives you an idea of the scale, and the green branching stalks are the same plant.

Fruiting Stag's-horn Clubmoss

It is a Clubmoss, Stag's-horn Clubmoss (Lycopodium clavatum).  It is similar to another Clubmoss, called Interrupted Clubmoss (Lycopodium annotinum) which I have seen near Wolftrax.

They both seem to grow in heathery places and are only easy to spot when there is a bare patch of ground. If you are not sure which one you have found, look carefully at the "leaves" which are scales along the stem. the Stag's-horn Clubmoss has white hairs at the end of each scale.

Clubmosses are not mosses, but belong to a group of plants that produce spores.  Nowadays you find clubmosses in mountainous areas and they are all small but millions of years ago there were tree-like Clubmosses that grew to 45m!  You can read more about Clubmosses here.
I put a sample of the Stag's-horn Clubmoss under the microscope to take a picture of the cones (the yellow parts that produce the spores).

I left the sample under the microscope and had a look at it just now - and got a surprise! The cone scales have opened up and released a little pile of yellow spores.
Spores of Stag's-horn Clubmoss
The spores are called Lycopodium powder or Dragon's breath and can be bought on the internet.  They are used in science experiments and cosmetics as they have two opposite properties - they don't get wet, and the powder can burst into flames explosively when sprinkled over a flame. Hmmm- what to do with my little pile....
