I guess I need to update the image 🫣

A new white-flowered species of Gagea has been discovered in the Fergana Valley of Uzbekistan and Kyrgyzstan.

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.

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

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.

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.

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.

🎓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

Illustration of Muscari tenuiflorum from Jacquin’s Flora Austriaca (1774: t. 126), showing a bulbous plant with narrow leaves and an inflorescence bearing fertile flowers and a short tuft of sterile flowers at the apex.

📜 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 🇬🇷.

Four images of Bellevalia specimens. A–B: B. shiraziana in rocky habitat in southern Iran, showing low rosettes with fruiting scapes. C: Herbarium specimen of B. shiraziana (holotype). D: Herbarium specimen of B. decolorans (holotype) showing bulb and scape.

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.

The June solstice has passed, which means we have a fresh update for our WFO Plant List! The big news since December is we now have more than 200 named co-authors on the WFO Plant List. Watch to see what else is new and visit worldfloraonline.org to browse the Plant List.

So we now have two #PlantScience specific Clusters of Excellence in Germany... well done! 👍

A honey bee collects nectar from the densely packed pink flowers of Echium wildpretii. The tubular blossoms are arranged along a tall inflorescence covered in fine hairs, with greenhouses reflecting in the background.

A row of tall Echium wildpretii plants growing along a greenhouse wall at the Bonn Botanic Garden. The plants have silver-gray rosettes and striking pink flower spikes, all in full bloom under a sunny sky.

Insights from morphological investigations and molecular phylogenetics reveal a new synonymy in Bellevalia (Asparagaceae: Scilloideae) in Iran | Phytotaxa

📢 New synonymy in Bellevalia!

Morphology + molecular data = 🧬 one species, not two: B. shiraziana is now B. decolorans.
Endemic, rare, and finally resolved.

Close-up of the flowering spike of Puya alpestris ssp. zoellneri, showing dense clusters of turquoise-green flowers with vivid orange stamens and unopened green buds arranged spirally.

Tall, upright inflorescence of Puya alpestris ssp. zoellneri rising above Chilean scrub vegetation, with its flowering head densely packed with turquoise blossoms; cactus and agave-like plants visible in the background.

Ever seen teal flowers? 🟢🟠

Puya alpestris ssp. zoellneri looks unreal—metallic blooms with orange stamens, bird-pollinated & found only in #Chile 🇨🇱. All six Chilean #Puya species are endemic & form a distinct clade in this ancient genus.

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.

Spring just got more exciting! The #Scilloideae TEN is now part of the #WFO family, diving deep into the taxonomy of #bulbs. From #Hyacinthus to #Ornithogalum, we're unearthing the taxonomic secrets of these #geophytes. Join us on this botanical journey.

Absolutely—still amazes me how often they nailed it.

Awesome. I guess this makes TCD the first herbarium in the world to pull this off—setting the gold standard for Boraginales, no less! 😜
