AND THEIR CULTURE.

distinct in imported specimens, cannot be trusted as a distinguishing' 

 character _, since cultivated bulbs of JVashingtoniaauw proper arc nearly 

 identical with those of Purpnreum, and even the points of difference 

 between the native bulbs of both plants are not more than can readily 

 be accounted for as being due to difference of soil and climate.* 

 HiimboIcUii, although very different to WnsMni/iowanum in its flower, 

 has an ovoid, oblique bulb, somewhat similar in shape to the smaller 

 figure, but occasionally it approaches the rhizomatous habit of 

 Wasliingtoniaiium, as seen in the larger figure.

L. Tigrinum. — The bulbs of this variable plant are, according to Mr. 

 Baker, "^ perennial, globose, with oblong, lance-shaped, acute scales."''

The specimen selected for me by the Colchester Bulb Company was, 

 as shown in the engra\'ing, as large as an Orange, and of a similar 



* 1 can scarcely agree to this. 



t The large figurt^of LcichtHnii is true, but fig. Xo. 3 is not so correct, the tip, or 

 young growth, is in reality very slender, like a small spike, in the figure it is triangular, 

 with a broad base ; the scales ought to be fewer, broader, and the bulb Hatter at the 

 apex. The figure given reminds me more of Concoloi-.
