Palicourea rigida, a robust shrub in the coffee family with leathery leaves and bright yellow flowers occurs in the savanna of South America. It's toxic to mammals but used as a traditional folk medicine.

This little primate is so successful that it has invaded not only Rio but also Buenos Aires, but it's not its fault. It's originally from northeastern Brazil and was introduced to southeastern Brazil and Argentina by people (through the pet industry). The common marmoset, 普通狨

The only Puya species I encountered on the way to Mt. Roraima. Unlike many other bromeliads, species in this genus are all terrestrial and can tolerate harsh conditions, such as arid, high-altitude climates in South America.

The Roraima black frog (Oreophrynella quelchii) is actually a toad and considered a "living fossil" because it belongs to a highly ancient, primitive lineage of amphibians that has survived virtually unchanged for millions of years due to geographical isolation. They don't jump but climb instead. Also, their eggs hatch directly into miniature frogs, skipping the tadpole stage.

Burmannia bicolor, a little mycoheterotrophic herb native to Central America and northern South America. It can photosynthesise but relies heavily on symbiotic fungi in the soil to obtain the nutrients it needs.

I figured out that the best time to do bird watching in the Amazon is right after the afternoon storm. Within 10 minutes, I saw two toucan species: white-throated toucan (Ramphastos tucanus) and chestnut-eared aracari (Pteroglossus castanotis).

This is a smaller Connellia bromeliad on the summit of Mount Roraima (compared to C. augustae). It is a clump-forming lithophyte, almost like a cushion plant on rocks, with bright rose-pink flowers that are pollinated by hummingbirds.

Lucky me, found a brown-throated sloth in the Atlantic Forest near Rio de Janeiro. This is a female one, because if you look carefully, she is carrying a baby on her belly.

Sloths are not rare, but they are difficult to spot in the Amazon because they stay high in the canopy and barely move. Photographing it, especially its face, is another challenge; they always make sure their faces are behind branches and leaves. This is a pale-throated sloth near Manaus. 白喉三趾树懒

Didn't know there are ant-house plants in Melastomataceae. This Venezuelan shrub, Miconia tococa, is famous for myrmecophytism - it has a pouch (domatia) at the base of each leaf that provides shelter for ants, and in return, the ants defend the plant and reward it with nutrients (ants' organic waste).

Heliamphora nutans x glabra, a naturally occurring hybrid on the summit of Mt. Roraima. It is larger and more vigorous than both its parent species and is apparently easy to grow in cultivation.

In the Venezuelan savanna, I saw this interesting sedge species, Bulbostylis paradoxa. Looks like a mini Xanthorrhea from Australia, and it is also pyrophilic; the difference is that Xanthorrhea takes weeks to flower after a wildfire, and this flowers within 24-72 hours, fascinating!

Miltonia regnellii, a beautiful orchid from the Atlantic forest of Brazil. 短唇丽堇兰。

Stegolepis guianensis, a distinct perennial herb endemic to the Guiana Shield, has long, flat leaves and tall, bright yellow flowers. It thrives on wet, rocky, and acidic soils. The ones at the foot of Mount Roraima are significantly larger than the ones on the summit.

Saw an eastern small-eyed snake on the way home at night. This beautiful reptile is native to eastern Australia (QLD, NSW, VIC) and is highly venomous, a member of the cobra family (Elapidae).

Orectanthe sceptrum, endemic to the Guiana Shield, grows on wet rocks and rocky terraces. Striking perennial subshrub up to 2 m tall, with densely crowded, glaucous leaves resembling a pineapple and blooms with bright yellow flowers.
