G78 SUPPLEMENT.— GERANIACE^. 



hence we have followed the suggestion of the latter author in respect to its 

 arrangement, — Tlie jilant is called Spatulum or S-paClum by the natives, 

 who gather the rools and employ them largely as an article of food.. The 

 bark being stripped off", the white inner portion is boiled in water, when it 

 forms a substa,nce similar to Salep or boiled Arrow-root. The dead root, 

 according to Nuttall, almost dissolves into starch by . maceration in cold 

 water. The roots are so tenacious of life, that specimens in Lewis's herba- 

 rium, as Pursh records, showing some signs of vegetation, were planted in a 

 garden at Philadelphia, where they grew for a year ; and Douglas's speci- 

 mens, treated in tlie same way, vegetated for a short time in the garden of 

 the London Horticultural Society. 



Order ELATINACE^. 



1. ELATINE, J}- 203— Add sp. : 



2. E. (Merimea) Texana (Hook.) : diffusely branched, ascending, pube- 

 rulent; leaves oblong-spatulate, rather acute, serrate, tapering at the base 

 into a slight petiole, bistipulate ; flowers pedicellate, mostly solitary in the 

 axils of the leaves ; sepals (ovale-acumioate), petals, stamens, and short 

 styles or stigmas 5 ; seeds marked with dotted lines. — Merimea (an Bergia?) 

 Texana, Hook. ! ic. pi. t 278. . 



Texas, Drummond! — Stems 6-10 inches in length, minutely pubescent 

 with short and thick spreading hairs. Sepals denticulate, rather longer than 

 the narrowly oblong obtuse petals. Stigmas, or short styles, distinct. — This 

 plant certainly falls into Elatine, as characterized by Arnott, whose views we 

 had adopted in ;the body of this work ; and we know not how Merimea of 

 Cambessedes is to be sufficiently distinguished. The dehiscence in this 

 plant is not loculicidal, which Arnott states to be the character of the order, 

 nor is it truly septicidal, but septifragal. 



Order LINAGES. 



1. LINUM, 2^- 204. 



The Texan species (no. 37, of Drummond's 2d Collection) which we had 

 doubtingly. referred to L. selaginoides, proves to be a different species. The fol- 

 ■ lowing should be substituted in place of our character, &c. 



5. L. multicaule ,(Hook. ! mss.) : annual; stems (5-10 inches high) usually 

 much branched from the base, rigid ; leaves subulate, mucronate-cuspidate, 

 1-nerved, closely appressed and imbricated ; flowers somewhat corymbed ; 

 pedicels very short ; sepals ovate, rigid, obscurely 1-nerved, strongly cuspi- 

 date, with broad scarious staiewliat ciliate-serrulate margins ; ovary com- 

 pletely 10-celled; styles united above the middle. 



Order GERANIACE.^. 



1. GERANIUM, >. 206. 



2. G. alhijlorum. — This species was first published by Ledebour, under 

 the same name {Fl. Alt. 2. p. 230, S^'ic-i^l. Ross.-Alt. t. 18. Add syn. G. 

 Kichardsonii, Fisch. Sf Meyer, ind. sem. 1837; who have changed the name 

 on the supposition of its being different from the Siberian species.
