634 JOTCAGINACE.E. ARROW-GRASS TRIBE. 



A pretty plant, well distinguished by its large arrow- 

 shaped leaves, and whorled panicles of delicate, flesh- 

 coloured flowers, both of which rise 6 8 inches out of 

 the water. This is one of the very few plants which 

 neither smoke nor buildings have driven out of London, 

 there being still large beds of it in the Thames, near 

 the Temple Gardens and Hungerford Market, where the 

 eager botanist may even yet gather fine specimens. Fl. 

 July September. Perennial. 



ORD. XCIIL JUETCAGINACILE. ARROW-GRASS 

 TRIBE. 



Flowers perfect ; sepals and petals alike, green and 

 small ; stamens 6 ; ovaries 3 6, superior, united or 

 distinct ; carpels 3 6, 1 2 seeded. A small order of 

 marsh plants, with linear leaves, all proceeding from the 

 root, and spike-like clusters of inconspicuous flowers ; 

 found in many parts of the world, and possessing no 

 remarkable properties, 



1. TRIGLOCHIN (Arrow-grass). Flowers in a spike ; 

 sepals and petals 6 ; stamens 6. (Name from the Greek 

 treis, three, and glochis, a point : from the three points 

 of the capsule.) 



1. TRIGLOCHIN (Arrow-grass). 



1. T. palustre (Marsh Arrow-grass). Fruit linear, 

 of 3 combined carpels. Marshy places, frequent. A 

 plant with something of the habit of Plantago maritima, 

 from which it may easily be distinguished by its fewer 

 flowers and slenderer spike, as well as by the different 

 structure of the flowers. The leaves are linear and 

 fleshy. Fl. June August. Perennial. 



2. T. maritimum (Sea Arrow-grass). Fruit egg- 

 shaped, of 6 combined carpels. Salt marshes, common. 

 Like the last, but well marked by its rounded, not linear, 

 capsule. FL May September. Perennial.
