At lunchtime I took the camera for a walk

Cactus Garden A much-loved campus feature; students and faculty campaigned to save it from being swept away by the new Alumni Plaza.	Barrel Cactus Fruit An experiment in close-up. (Warning: if you click through to the gallery, you'll see a reasonable-sized version, but the underlying image is 1.7Mb; the others I shrank down to something more sensible.)
Saguaro The characteristic colour and texture of the Sonoran Desert.	Aloes Yes, strictly speaking they're succulents. Also, I'm not 100% sure they aren't agaves. The two are very similar in appearance.

It was very bright, and I rapidly discovered that the LCD display is hard to see under those conditions; also, the screen is too small to make it obvious when the picture is out of focus. Obviously I need to practise more, but I'm modestly pleased with these.
