Pollen, 106. (A paper “ On Pollen,” by M. P. Edge- worth, was read at the Liniieaii Society’s meeting, March 2, 1876. The author treats of the shape and relative size of the pollen- grains in many orders of x»lants. About 400 ditferent species have been investigated by him—each mea- sured to scale, and sketched accor- dingly. Some families of plants, he finds, i)resent great uniformity of figure and size in their pol- len ; but, on the contrary, others are as notable for diversity, even in what would seem closely - related species. In the ‘Gardeners’ Chron- icle’ (1876) Mr W. G. Smith gives careful sketches of about 100 sorts of pollen, the results of his observa- tions being much the same as those obtained by Mr Edgeworth.)

(The extremely thin tubes emitted by pollen-grains commence to grow in about thirty minutes after they are placed in Hoya nectar or Agave mucus on a strip of thin glass or microscopic slide, and they continue growing rapidly until the nectar dries up. These tubes are traus- pareut, and a current or circulation of their contents is plainly visible under a moderately i>owerful glass.) Pollen-tubes ofTigrklia, 113.
