Hypostase, The. By Ph. van Tieghem (Ann. Sc. Nat. (Bot.) xvii. 

 pp. 347-362 ; 1903). — The object of this paper is to draw the attention 

 of workers on the anatomy of the ovule, seed, and fruit to the necessity of 

 making accurate observations on the hypostase. This is a layer of cells 

 lying below the embryo-sac of the ovule of flowering plants. This layer 

 is distinguished by the cell-walls becoming gradually lignified, and shoA\s 

 the usual reactions with iodine green or fuchsin. The position of the 

 hypostase is said to determine whether the seed will have a perisperm. A 

 few examples are given to bear out the suggestions made. — W.G.S.

Injurious Insects in Montana. By R. A. Cooley (U.S.A. Exp. 

 Stn. Bep. 1902, pp. 80-87).— A list of 29 native and 27 introduced insects 

 which are commonly injurious to plants in Montana is given. The 

 Cottonwood Leaf -beetle (Lina scripta Fabr.) is injurious particularly in 

 the larval state, to leaves of Willow and Cottonwood. The perfect insect 

 somewhat resembles the Colorado beetle, but is flatter and from 3 to 4 

 lines long. Paris green (1 lb. to 100 gallons of water) sprayed on the 

 foliage is a good remedy. The cucumber flea-beetle ( Epitrix cucumeris 

 Harris) did great damage to Potato foliage in many places. Bordeaux
