444 Mr Berwick on Glands in the Cotyledons. 



Fig. 4. Whorl of glands in axil of cotyledons of seedling, fig. 3, 

 enlarged ; gl. an adult embryonic gland, which measured 

 in height '8, across "SS mm. ; p., plumule surrounded by 

 leaves ; r., bundle of raphides in the other adult cotyle- 

 donary gland; v. r., vertical raphides ; s. v., spiral vessels.

 line.

„ 7. An adult cotyledon: w. p., water pores; li., hair; v. r., vertical 

 raphides. 



,, 8. A seed with its radicle protruding (nat. size). 



„ 9. Eoot-cap region of radicle in fig. 8: v. r., vertical raphides ; 

 h. r., horizontal raphides.

Postscript. — In an embryo of Gcdium cruciatum, Scop, (from 

 a fresh seed of this year), I have discovered two embryonic 

 glands similar to those occurring in the embryo of Galium 

 Aparine, L. In numerous other embryos of G. cruciatum 

 examined, only one gland was detected, but this was due to 

 the difficulty of dissection. The largest gland seen might 

 measure rt of an inch in length. 



In certain other native members of the order Buhiacece 

 examined, the embryonic glands, if present, escaped detection.
