results obtained in this work was from fixed and stained material. In 

 both plants the secreting cells are full of proteid granules in the resting 

 condition. As secretion begins these granules gradually disappear. In 

 Zea this disappearance coincides closely with the consumption of the 

 endosperm ; in Pha>nix, however, the granules disappear long before the 

 endosperm is dissolved. There is no evidence that solid matter is extruded 

 from the nucleus. — A. D. C.

Eremuri, The. By W. Irving (Garden, No. 1724, p. 376 ; 3/12/1904). 

 Now that the culture of these noble plants is becoming better known they are 

 rapidly increasing in favour, and they form a striking feature in many 

 gardens, with their stately stems bearing long racemes of numerous 

 flowers. The genus consists of about twenty-five species in all, and of 

 this number ten have been introduced into cultivation in our gardens. 

 Several of the species are really handsome plants, well suited for warm, 

 sheltered positions, among low-growing shrubs or loose-habited plants. 

 They thrive admirably in rich sandy loam, which should be well drained, 

 as they dislike anything in the way of stagnant moisture. There are 

 numerous stout and fleshy root fibres, disposed horizontally around a 

 central crown, so that planting must be carefully done, particularly as 

 the roots are very brittle. They should also always be in a position 

 where the roots will not be disturbed or injured by digging. — E. T. C. 



Eremurus Elwesii : ? Hybrid or Species. By S. Mottet (Bev. 

 Hort. pp. 18-19, Jan. 1, 1904 ; 1 woodcut). — M. Mottet considers it a 

 spontaneous hybrid between E. himalaiacus and E. robitstus, though 

 artificial crosses between these two have given different results.
