directions, and present a very pleasing appearance. The roots, meanwhile, 
penetrate into the saucer, which they line with a tangled mass of fibres. In 
its wild state it flowers in July and August. 
4. Round cluster-headed Mud-rush (J. holoschwnus).— Spikelets 
collected into globular heads. A distinct and very handsome rush-like plant, 
with round robust stems, 3—4 feet high, from about six or eight inches 
below the summit of which proceeds a panicle of six to twenty globular 
heads, of the size of small marbles, accompanied by a long spreading or 
deflexed bract. Said to grow on the sandy coast of Somerset and Devon, 
though no specific locality appears to be named but Braunton Burrows, an 
extensive tract of sand on the north coast of Devon, and Berrow, Somerset. 
Here it undoubtedly grows, but can scarcely be discovered without some 
labour and difficulty, owing to the tangled jungle of grass and rushes, which 
must be penetrated and searched by the botanist. The Berrow station, 
discovered by Mrs. E. 8. Gregory in 1896, affords a small, depauperate form. 
It flowers in August and September. By some authors Jsolepis is merged in 
Scirpus. 
8. CLUB-RUSH AND BULRUSH (Scirpus). 
* Spikelets numerous ; stem round. 
1. Common Bulrush (8. lacistris).—Spikelets forming a dense. com- 
pound terminal panicle; glumes notched and fringed, smooth. Margins of 
lakes and in running water abundant, varying, according to the depth of 
the water, from 4—8 feet high. This is one of the few British CypERACEX 
applied to any economical purpose, being often made into mats, and, when 
twisted, being also used to form the seats of what are called rush-bottomed 
chairs. Coopers employ them in the caulking of casks. Many persons are 
in the habit of applying the term “ Bulrush” to any tall rush-like aquatic, 
especially to plants of the genus 7ypha, to which last the name Reed-mace 
is far more appropriate. It flowers from June to August, and is generally 
distributed throughout the British Isles. 
2. Glaucous Bulrush (8. tabernemontdni).—Spikelets forming a loose 
compound terminal panicle ; glumes notched and fringed, rough. Closely 
resembling the last in habit, but much smaller, seldom exceeding the height 
of two feet, and readily distinguishable by the glaucous hue of its stems. 
In the west of England it is far the commoner species of the two, and is 
very abundant on the banks of the Clyde. It grows also in many other 
places, especially near the sea, and flowers from June to August. Some 
botanists regard it as a sub-species of S. lacustris. 
* * Spikelets numerous ; stem triangular, leafless above ; stigmas 2. 
3. Triangular Club-rush (S. ¢riqueter).—Spikelets clustered, some 
stalked, overtopped by the acutely triangular, usually leafless, stem; glumes 
notched, the lobes ending in a little point. Muddy banks of the Thames 
near London, in the river Arun, Sussex, and from thence to Cornwall. It 
grows from 3—4 feet high, and flowers in June and July. 
4. Sharp Club-rush (S. pungens).—Spikelets about 3, sessile, sur- 
mounted by the acutely triangular stem ; glumes notched, the lobes acute ;
