Hypoxidaceae (Asparagales) are a family of herbaceous rosettes with folded (plicate) leaves. It’s a small family with fewer than 200 spp. Hairs are prominent, & flowers are often yellow. This is Hypoxis hirsuta, which grows in the woodlands around my house. #Hypoxidaceae #Botany 🌾🧪🌱

A new species of Allium, A. erimomeli, is described from the volcanic islands of Milos and Antimilos, Greece. This hexaploid species highlights the role of polyploidy and insular isolation in A. sect. Codonoprasum diversification. ➡️ doi.org/10.5091/plec...

New paper! A checklist of the plants endemic to the Lesser Sunda Islands (S Indonesia and Timor-Leste). For conservation we need to know where these plants are and if they are threatened, and we know so little about either. 51 species haven't been seen in >120 years! doi.org/10.3897/phyt...

Eastern skunk cabbage blooms early as it melts its way out of winter. Its fleshy inflorescence generates heat, melts snow, & releases a pungent odor that attracts flies & beetles when little else is available. Often called a “famine food,” it’s toxic & required repeated boiling to become palatable.

Galanthus reginae-olgae subsp. vernalis is a most common #snowdrop in coastal parts of Montenegro. So happy to catch it still in bloom. Its foliage is very distinct with an impression of median white stripe such as in Crocus or Ornithogalum.

Nice outcome of this paper is that Thismia kobensis is just another Thismia species that behaves as normal plant species (i.e. it has multiple localities). Thismia is probably not extremely rare as popularly believed but just extremely overlooked and hard to find.

Close-up of Muscari comosum in flower. The inflorescence shows a dense terminal tuft of sterile, vivid violet to bluish-purple flowers, contrasting with the lower, widely spaced, drooping fertile flowers that are pale brownish-yellow with darker tips. The background is a natural, grassy habitat with rocks.
