🌱 Just published! I am thrilled to see our Flora of Greece treatment for the genus #Muscari (Asparagaceae) online.

Check it out: portal.cybertaxonomy.org/flora-greece...

Also check out the other treatments available for your next trip to Greece!

#Botany #Scilloideae #Taxonomy #FoG

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.

Cultivated wild beauty from Japan! 🇯🇵

#Cirsium purpuratum, native to forest edges and slopes in Japan, is thriving in full-sun, dry habitats at #Bonn Botanic Gardens 🌞🌿

Its striking flowers & tolerance suggest real potential as a garden plant in Europe.

🎓PhD student M. Pourghorban leads this new study tracing the evolutionary history of #Cynoglossum
🌍 Turns out: the genus originated in the Irano-Turanian region and spread westward

A @humboldt-foundation.de funded 🇮🇷🇩🇪 collab, now out in Cladistics: 📄 doi.org/10.1111/cla....

#Boraginales #IranFlora

Twelve photographs showing the diversity of flowers and nutlets in Cynoglossinae.
Top row (a–d): Blue to red flowers of Cynoglossum amabile, C. creticum, C. dioscoridis, and Lindelofia stylosa.
Middle row (e–h): Red to pale flowers and fruiting structures of Paracaryum rugulosum, Rindera lanata, Solenanthus apenninus, and S. circinatus.
Bottom row (i–l): Diverse nutlet morphology in C. creticum, S. circinatus, Paracaryum cyclhymenium, and inflated calyces of R. lanata.
Photos highlight variation in corolla color, hairiness, fruit shape, and dispersal structures across the clade.

Time-calibrated phylogeny of Boraginaceae subtribes, including Microulinae, Amsinkininae, Bothriosperminae, and Cynoglossinae, with ancestral area reconstruction.
Color-coded circles at nodes represent inferred ancestral ranges across global biogeographic regions (e.g., Irano-Turanian, Mediterranean, East Asia).
The tree is divided into three major clades, with Clade III containing most Cynoglossum species.
Inset maps show reconstructed dispersal pathways from the Irano-Turanian region to Europe, Africa, and beyond. A color key explains regional codes (A–F), and global map at top right shows their geographic extent.

📜 This stunning 1774 illustration by Jacquin is now the lectotype of #Muscari tenuiflorum.

We typified three iconic species—M. armeniacum, M. commutatum & M. tenuiflorum—laying groundwork for future revisions & #FloraOfGreece 🇬🇷.

The systematics of #Bellevalia remain a challenge—but step by step, we’re making progress!

🔬 Together with colleagues from Iran 🇮🇷, we revisited a puzzling species pair using morphology, fieldwork & molecular tools.

Four images of Bellevalia specimens.

A collage of colorful flowering inflorescences from various genera within the plant subfamily Scilloideae (Asparagaceae), displayed against a black background. The image showcases the morphological diversity of the group, with blooms in shades of blue, purple, pink, yellow, and white. Floral forms range from compact racemes to loose spikes and dense spherical clusters, representing genera like Muscari, Scilla, Ornithogalum, and others commonly found in Mediterranean and African regions.
