Interesting web site, Eric.
The gallery:
http://www.androsace.org.uk/gallery.htmhas a good selection of images.
Link on that page takes you to Jozef Lemmens' excellent website:
http://www.androsaceworld.com/What a range of photos.
On which van be grown from Chiltern Seeds is Androsace alpina
On that site I see 20 images of that plant!
and another Chiltern item: Androsace villosa
20 images (many of which are subsp./var. though)
Isnt it fantastic that plant enthusiasts dedicate so much of their spare time to share in this way.
