He divided the mosses into six genera: Mnium, Hypnum, Polytrichum, Bryum, Sphagnum and Lycopodium — classifications that are useful today.

他把藓类分为六个属：提灯藓属、灰藓属、金发藓属、真藓属、泥炭藓属和石松属，这些分类在今天仍然有用。

During my walks along the Thames, I kept his stunning illustrations to hand and learned to differentiate polytrichum from mnium in his company.

在我沿着泰晤士河散步的时候，我把他那令人惊叹的插图带在手边，还在他的陪伴下学会了区分金发藓和提灯藓。
