California Holly: How Hollywood Didn't Get its Name

In Nancy Dale’s 1986 epic tome of Southern California native plants, Flowering Plants, she has this to say about Toyon — aka California Holly, Christmas Berry, or, if you’re a botanist, Heteromeles arbutifolia:

“It is thought that masses of this native shrub growing on the hills above Hollywood gave the community its name.”

This idea of floral origins for Hollywood is romantic. It’s also not true. Hollywood got its name for a much more mundane reason: someone wealthy liked the sound of it.

In 1886, Harvey Henderson Wilcox, a rich prohibitionist from Kansas, and his wife, Daeida, purchased 120 acres of apricot and fig groves near the Cahuenga Pass at $150 an acre. Harvey, an inveterate businessman, realized he could make a lot of...

Bird's Nest Fungi, Exploding Eggs, and Mushroom Soup

Yay! Today I documented the first bird's nest fungus, Cyathus sp., in the North Campus. For months, I have been looking forward to finding these fascinating, weird, and wonderful fungi. When North Campus Director Carol Bornstein told me she had found some, I immediately knew I had to blog about them.

Bird's Nest Fungi with my finger for scale.

As you can see, this fungus looks like a miniature bird's nest with oddly flattened eggs in it. Mycologists refer to them fondly as BNFs, bird's nest fungi. The "eggs" (periodoles to be geeky and precise) are actually packages containing thousands and thousands of spores. When a raindrop, or some other drop of water, hits the periodole it causes a miniature explosion. The spores are released and propelled out of the cup (some spores can be projected over six feet in this manner),...

First Baby Oaks Sprout Up in the North Campus

The North Campus is the proud parent of some baby oak trees!

Carol Bornstein, our new Director of the North Campus Gardens, discovered a couple of oak saplings on one of her recent outdoor forays. The babies are coast live oaks, Quercus agrifolia, of which we recently planted several trees. We've also planted another species of oak, the Engelmann oak, Quercus engelmanni (we planted only three of this species). Both species reside in the section of the garden called the urban wilderness which is composed of several kinds of California native trees and shrubs.

This might be the mother oak!

Oak trees provide amazing habitat value,...
