 This is the gum ammoniac plant. ' ' It grows 

 principally on the plains between Yudecaust 

 and Kumisha, in the province of Irak, without 

 cultivation. The gum is so abundant that, 

 upon the slightest puncture being made, it in- 

 stantly oozes forth, even at the ends of the 

 leaves." It will grow freely in ordinary gar- 

 den soil, and is propagated by seeds,

Dortmanna, Don. After one Dortmann, said 

 to be a Dutch apothecary. Linn. 5, Or. 1, 

 Nat. Or. Lobeliaceoe. The species of this genus 

 are singular and beautiful plants, but require 

 a good deal of care in cultivation. D. lacus- 

 tris succeeds best planted in a pot of gravel, 

 and placed in a pond or cistern, so that the 

 plants may be about six inches under the 

 water. The other species may be grown in a 

 pot half filled with peat earth, and the rest 

 with sphagnum, in which the plants must be 

 set, and the pot placed in shallow water, so as 

 not to immerse the plants. They may be in- 

 creased by division. Synonymies: 1, Lobelia 

 Dortmimna ; 2, L. paludbsa.

 mental plant, requiring a warm part of the

 latter is preferable. It may be increased from 

 suckers, which are seldom to be obtained, ex- 

 cept by cutting a large plant down, or taking 

 out the heart of the plant ; in either case, it * * 

 will throw out suckers,
