Having finally figured out how to wiki images, I've posted images and 
brief comments on a few more bulbs:

Homeria collina (Moraea c. these days but we still have a Homeria 
page.)
Oxalis 'Ione Hecker'
Crocus kotschyanus

These are accessible from the relevant wiki pages in the ordinary way.

The pictures aren't technically the greatest, but I've made an effort 
to provide images that fairly faithfully represent the true colors of 
these plants' flowers.

Some comments on digital photography (using a cheap little Sony 
camera):

1. Always use a tripod. Except in bright sun, exposure times are long 
enough to make shake a problem.

2. Lowering the exposure value (EV) by 1.7 or 2.0 units (half a stop 
to a full stop), immensely improves pictures taken in full sun and 
gets rid of the overexposed glare one gets on petals. I find that 
adjusting the gamma value during post-processing helps lighten up 
areas that may be too dark.

3. Lowering the camera's contrast and/or saturation also helps in 
some cases. It appears that digital cameras, like film cameras, 
converts all bright reds into a single undifferentiated fire-engine 
red otherwise.
