KAGENECKIA 351 



rhiz. giving off one leafy shoot each year. The I. are of various types, 

 with large sheathing bases. Some are flat and grass-like, others 

 needle-like, and still others centric in structure and standing erect. 

 The infl. is a dense head or panicle, of cymose construction (usu. 

 rhipidia or drepania). In some sp. it appears to be lat. on a leaf-like 

 cylindrical stem, but is really only pushed to one side by the bract of 

 the infl. Fl. protog. and wind-fert. 



Rushes are largely used for making baskets, chair bottoms, &c. 

 J. squarrosus L. is common on hill pastures in Brit. ; it is eaten by 

 sheep and forms a valuable part of their fodder when grass is scarce.

Juniperus Tourn. ex L. Coniferae (Pinac. 42 ; see C. for genus cha- 

 racters). 30 *. The juniper,/, communis L. (Asia and Eur. incl. 

 Brit.), and J. Oxycedrus L., &c. have needle 1. throughout life; 

 others, such as J. Sabina L. , the savin (Eur. As.), have small 1. 

 closely appressed, as in Cupressus. Seedling forms of these are known 

 (see Retinospora). The cone consists of i 4 whorls of scales, one 

 only being fertile, as a rule.. In ripening the whole becomes a fleshy 

 mass enclosing the hard seeds, and forming a good imitation of a true 

 berry. The fruit is eaten by birds. That of/", communis is used in 

 making gin. The wood of/, virginiana L. is the red cedar used for 

 pencils ; others also give useful timber.

 plants. Aerating tissue is well developed (cf. Sonneratia, Sesbania). 

 In/, repens L. (/. diffusa Forsk.), when growing in water, two forms 

 of root develope, ordinary anchorage roots and erect spongy roots 

 which grow upwards, often till they reach the surface of the water. 

 The bulk of the tissue consists of aerenchyma. In /. suffruticosa L. 

 (/. salicifolia H. B. et K.) there is an erect stem, whose lower part 

 is covered with aerenchyma if growing in water (cf. Lycopus). If the 

 plants be grown on land none of these phenomena appear. [Figs., &c.,
