Spring flowers

Three more photos taken with the USB microscope. The top image is of the Marchantia polymorpha liverwort that grows on the surface of overwatered plants in my greenhouse. The objects in the centre of the cupule are tiny buds called gemmae, miniature liverworts that will begin to grow when they are splashed out onto the soil surface by the spray from the watering can. You can also see the air pores in the surface of the liverwort thallus quite nicely. The other two images are of a lesser celandine and a dandelion. One minor problem with this USB microscope is that the images can be a bit flat, especially if the objects are predominantly one colour, as the ring of LEDs that provides the illumination produces shadowless lighting.
