Sloaneas are trees that I’ve been wanting to see for a long time, the reason being that it was the inspiration for a very interesting theory, called the Durian theory, which paints a theoretical picture of how primitive flowering plants may have looked. Key to this theory is spiny fruits, which is what Sloaneas have.

I think that the small stipules at the point where the leaf connects to the stem and the swollen bases of the leaf stalk are quite characteristic.

Interestingly, this genus is related to Quandongs (Elaeocarpus) to which it bears no resemblance at all.


About David Tng

I am David Tng, a hedonistic botanizer who pursues plants with a fervour. I chase the opportunity to delve into various aspects of the study of plants. I have spent untold hours staring at mosses and allied plants, taking picture of pollen, culturing orchids in clean cabinets, counting tree rings, monitoring plant flowering times, etc. I am currently engrossed in the study of plant ecology (a grand excuse to see 'anything I can). Sometimes I think of myself as a shadow taxonomist, a sentimental ecologist, and a spiritual environmentalist - but at the very root of it all, a "plant whisperer"!
