There are physiological ways of avoiding the daily drought stress of epiphytism. Many epiphytes are CAM plants, so they open their stomata only at night, when it's cooler & transpiration isn’t so harsh. Orchids, bromeliads, & hoyas (📷: H. kerrii) are familiar CAM plants. #Apocynaceae #Botany 🌾🧪🌱

Plumeria caterpillars (Pseudosphinx tetrio) feed on Plumeria & other Apocynaceae. They look bad-ass aposematic, but it may be false advertising. Some research shows that they excrete, rather than sequester, the toxins of the host plant. #TeamMoth #Apocynaceae #Aposematism #Botany 🌾🧪🌱
Photo of an orange-and-black butterfly nectaring on the purple flowers of Stachytarpheta jamaicensis.
Monarch butterfly larvae (Danaus plexippus) sequester toxic cardiac glycosides (cardenolides) from their host plants (Asclepias spp.). The toxins are passed to the adult butterfly, which is fearlessly aposematic. 📷: Mary Keim CCYBNCSA2. #Apocynaceae #Aposematism #Botany 🌾🧪🌱

A collage of two photos. The left panel shows a many-branched tree silhouetted against the sky. The right panel shows a dead, leafless tree against the sky.
Monocarpy is super rare among broadleaf trees (& absent from Gymnosperms). Cerberiopsis candelabra comes from New Caledonia. It’s a monocarpic forest tree! 📷: Florence Le Strat CCBYNC4 #Apocynaceae #monocarpy #Botany 🌾🧪🌱

Collage of four photos. All plants have leafless, green stems. The Euphorbia stem is thick and succulent. The Muehlenbeckia stem is flat and ribbon-like. 3 Photos by Scott Zona CC BY-NC 2.0.
When leaves are liabilities… leaves are expendable. It’s happened in unrelated lineages. Clockwise from upper left: Acacia aphylla (Tony Rodd CCBYNCSA2). Euphorbia abyssinica. Asclepias subulata. Muehlenbeckia platyclada. #Fabaceae #Apocynaceae #Polygonaceae #Botany 🌾🧪🌱

Nerium oleander is a beautiful but potentially deadly shrub with flowers in a range of colors. Native to the Mediterranean, it’s now common in warm regions worldwide. All parts are highly toxic—avoid planting it near pets or children!

We suspect the best time to collect pollen for ex situ #conservation is shortly after anthesis. But when do flowers open?
Ochrosia kauaiensis (Hōlei; #Apocynaceae) is Critically Endangered on the #IUCN Red List.
We used the ntbgarden.bsky.social Living Collection to capture this time-lapse video.
A summary phylogeny of Apocynaceae with the distribution of pyrrolizidine alkaloids, amino acid motifs of homospermidine synthase-like (HSS-like) genes, HSS-like pseudogenes, and alternative reconstructions of pyrrolizidine alkaloid origins and losses mapped on. Patterns of selection and functional evolution in HSS-like genes cannot distinguish between a single and multiple recruitments to pyrrolizidine alkaloid biosynthesis.

This #Stephanotis grows well despite being in a tightly planted mixed pot. Its flowering is not good. Just two clusters this year after one last year. Worth it

Mucking around with macro (oof – it's hard!) Love my tiny Sarcostemma vanlessenii flowers. They're related to Hoyas, which I also love.

Two or three open frangipani flowers. The flowers are pink with yellow centres with darker pink bleeding from the centre. Unopened buds on the flower cluster are visible with a background of green foliage
