NOTES ON LIMONIUM 75 



tellum, distinguished from that, usually at a glance, by the more- 

 branched scape with numerous sterile branches and laxer spikes, 

 and, at a closer inspection, by being much less tomentose on the 

 scape, by the almost glabrous bracts (the outer one more herba- 

 ceous also), and by the acute calyx-lobes. As far as I have been 

 able to judge from dried specimens, the character mentioned by 

 Becker regarding the presence of salt on the leaves holds good, and 

 is yet another distinction. From S. latifolia the plant is easily 

 separated by its larger calyx (with often intermediate teeth), 

 more glabrous scape, less rough leaves, more herbaceous outer 

 bract, &c. 



It has more than once crossed my mind that S. sareptana 

 might be the result of L. tomentellwn, with its decidedly hairy 

 bracts and calyx and rounded calyx-lobes, crossing with S. lati- 

 folia, which has glabrous bracts, less hairy calyx and acute calyx- 

 lobes. A careful examination of the living plants in their native 

 surroundings would probably soon decide this point, which, if 

 proved, would explain in a great measure the very varied facies 

 which the plant presents. 



I have been unable to find any figures of L. tomentellum that 

 can be called satisfactory, hence the plate now given. Trautvetter 

 (Z. c. 357) asserts that the S. Gmelini of Reichb. Icon. Crit. 237 is 

 his S. tomentella f. trachycauUs, but as that figure indicates a 

 plant with a very lax spike and acute calyx-teeth, it would seem 

 to fit var. sareptanum much better and to this I should assign it. 



The S. scoimria Pall, of Reichb. Icon. Grit. 236 is indicated by 

 Trautvetter as his glabella form of tomentella, but I think, in spite 

 of the rather large liowers shown on the plate, it really represents 

 L. Gmelinii as noted in Journ. Bot. 1909, 287, and has nothing 

 to do with any form of L. tomentellum.
