The Cholla Garden
The Colorado Desert in Joshua Tree National Park looked extremely patchy with respect to plant species distributions. There were large areas clearly dominated by a single species, such as Ocotillo and Cholla. Further, like other desert plants, the plants appeared to be distributed uniformly within patches.
Here’s a beautiful example of a dense patch of Cholla (Cylindropuntia bigelovii).

Cholla
Beyond the Ocotillo wash and patch, there were a few extremely spiny plants along the road in Joshua Tree National Park that caught my eye. I stopped to photograph this one, just before coming to the Cholla Garden, which, at the time, I wasn’t aware of.
Teddy-bear Cholla (Cylindropuntia bigelovii) is anything but friendly. I received a few barbed spines in my finger as I explored the cactus’ branching and green stem.
Multiple horizons
Happy Birthday, Allison!
Another year gone, yet not a single year older.

A Joshua Tree
I will never be closer to U2’s Joshua Tree than this.
Wait, this is closer
Piper
The diverse Piper genus (Piperaceae) is used as a model system for a variety of ecological studies, including work done by Dyer at La Selva on tritrophic interactions (i.e., plant [Piper] – caterpillar – parasitoid). It’s also economically important – we grind the dried fruit or seed to produce pepper.
Here is a flower spike of a common species in Cahuita –I have no clue which – and a spider with stabilimentum that was often present with patches of Piper.
Path at Cahuita
Boa leads a group of four Spaniards on a tour in Cahuita National Park…. I tagged along and got an opportunity to snorkel at Cahuita’s famed reef for free.
Ctenonotus cristatellus
This Polychrotid is a non-native to Costa Rica but is extremely common in parts of the Caribbean coast. It’s native to various Caribbean islands, such as Puerto Rico and Hispanola, and this one was caught outside Cahuita. The males not only develop a large, colorful dewlap, but also a crested tail, giving it the species epithet cristatellus. It’s fairly large and relatively distinctive in shape, similar to Norops capito.
