Sargant, Ethel and Agnes Robertson, The Anatomy of the 

 Scutellum in Zea Mais. (Annals of Botany. Vol XIX 

 No. 73. 1905. p. 115.) j ■ ■ 



A füll account of some observations first published in the 

 Report of the British Association Meeting in 1903 recording 

 the presence and structure of certain glandulär involutions of 

 the epithelial layer on the dorsal surface of the scutellum of 

 Zea Mais. A description is here given of the external morpho- 

 logy of the embryo, and of the vascular System of the scutellum. 

 Several separate vascular Strands run from the axis of the em- 

 bryo into the lower part of the scutellum, but a Single massive 

 Strand alone supplies the upper resion. Near its base this 

 Strand is collaterai, and in some cases the large phloem strand 

 IS divided into two groups separated by elements that cor- 

 respond to the sclerenchyma in a mature bündle of the stem. 

 Towards above the vascular Strand becomes amphivasal, and 

 numerous lateral branches are given off from its sides and 

 dorsal surface which end blindly a few cells below the epithe- 

 hum. These branches form a kind of transiusion tissue, and 

 are doubtiess connected with the fact that in Zea the scutellum 

 functions as a suclcing organ for a long time. Epithelial glands 

 also occur upon the scutellum of Coix Lachryma Jobi.
