of the cells on the outer side of the gland may break down, and thus 

 leave a simple membrane covering the secretion. The stalk of the glan- 

 dular hair is usually inserted in a depression in the surface of the leaf. 

 Glands of the same type have been described by Koepfl (Ueber d. 

 Anat. Charaktere d. Dalbergiccn. Diss., Muenchen, 1892, pp. 6, 57 and 

 58, t, Ij figs. 9rt and %) in two species of Centrolobium (Papilionaceae), 

 and figured by him in C. rdbustum^ Mart. Somewhat similar glands, but 

 of a different shape, were found by Dellien (Ueber d. Syst. Bedeutung d.
