Common British Plants: the top 30 vascular plant species – Poaceae

Which are the commonest plant species in Britain? Recently Dr M has investigated the 30 most common British plant species based on data in the New Atlas of the British and Irish Flora and the Online Atlas of the British and Irish Flora. The top 30 include species from 10 plant families including nine of the top twenty plant families. The 30 commonest species includes eight species

The Tribes of grasses 7: Nardeae

Cope & Gray (2009) refer to Nardeae as “an odd little tribe whose unusual spikelets give no clue as to its origin or affinities”.


Grass Identification: The Tribes of Grasses – 6 Meliceae

A small tribe with two genera – Melica and Glyceria – in Britain.


Dr M’s Top Twenty Flowering Plant Families: Poaceae

The Devil has the best tunes but the Poaceae surely has all the best words – LIGULE, AURICLE, GLUME, SPIKELET and LODICULE!


Grass Identification: The Tribes of Grasses – 5 Brachypodieae

In Britain the tribe Brachypodieae has just a single genus: Brachypodium with two species. The tribe has affinities to Bromeae (hence the common name false-brome), and Triticeae and also Meliceae (a post on tribe Meliceae coming soon!).


The culms have all the nodes!

One of the characters that marks out the Poaceae, the grasses, is the node. Grass nodes are the  funny “knobbly knees” on the grass culm (culm=the grass flower stem) and nodes are usually easy to spot. They maybe green or shades of brown or even reddish, round or elongated, hairy or glabrous.


Grass Identification: The Tribes of Grasses – 4 Triticeae

Dr M now turns his attention to the tribe Triticeae with 6 genera in Britain including the domesticated crop species and their wild relatives wheat (Triticum) and Barley (Hordeum) and Rye (Secale).


Dog zone grasses!

Urban habitats are many and varied!  Take the area around the base of lamp posts and street trees for example.  These familiar places are somewhat un-picturesquely, though very accurately, described the “dog zone”! This is a great habitat for various weeds which flourish because of what dogs do in the dog zone! One of them is the aptly named grass, Wall Barley (Hordeum murinum),

Grass Identification: The Tribes of grasses 3 – Bromeae

After posting the two large tribes (Poeae and Aveneae) Dr M is pleased to post this smaller (but perfectly proportioned) tribe Bromeae, the Brome grasses! The Brome grasses are extremely beautiful grasses with rather characteristic oval and awned spikelets, though the main Bromeae genus, Bromus, is rather close to Festuca, read on! The inflorescence is a panicle with laterally compressed spikelets with several to many

A Taxon for all time!

Dr M wrote this post for Catalogue of Life – Taxon of the Day, sign up to CoL Taxon of the Day in future for details of other favourite plants (Mondays) and animals (other days!). Dr M writes: Poaceae is a wonderful and important vascular plant family, the 5th-largest in the World, after Orchidaceae, Asteraceae, Fabaceae and Rubiaceae.  World-wide, Poaceae is divided into 28 tribes
