Last week, I met Hydrolea spinosa (photo) at Cambridge Botanic Garden. Tomorrow, I'll hear a talk on taxonomy of Hydroleaceae at Edinburgh Botanic Garden. The family has 1 genus & 11 species. Part of Solanales. This species doesn't even have its own Wikipedia page :(

Visited Comino today. Pancratium maritimum in bloom. My first ever experience of a rubbish bin dedicated to waste pineapples. Instagram craze of pineapple based cocktails on Comino, Blue Lagoon. No idea why. There is a somewhat whimsical 'history' of the craze here lovinmalta.com/opinion/sati...

Magnolia denudata (#Magnoliaceae) is another beetle-pollinated species. The pollinators are large #Coleoptera (#Scarabaeidae). The thermal image shows that the stamens & carpels heat up. AOX respiration generates the heat. Thermal image from bit.ly/3S58s0V

Photo of three fruits floating in water. The fruits are borne in white cupules.

Each nut of Hernandia sp. (#Hernandiaceae) is subtended by a white, cup-shaped bract. When the fruits drop, the bracts act like boats, ferrying the fruits away. Once in New Guinea, I waded through a shallow pool covered by rafts of tiny Hernandia boats. #dispersal #hydrochory #Botany 🌾🧪
