🌱 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.

Close view of a freshly opened flower head of C. purpuratum, revealing the bright magenta-pink florets and dark, hooked bracts. Close-up of a mature Cirsium purpuratum flower head with deep reddish-purple involucral bracts and hooked spines, photographed in strong sunlight. Whole plant of Cirsium purpuratum in cultivation, showing multiple nodding flower heads with dark purple bracts and large, lobed basal leaves. Zoom on a single large leaf of C. purpuratum, showing its broad, spiny margin and longitudinal venation.

🎓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 🇬🇷.

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