5 A. LOTOIDES (Lam. diet. 1. p. 316.) plant prostrate, gla-

 erect, subulate at the apex. Q. H. Native of China. A. 

 Sinicus, Lin. mant. 103. Sims, bot. mag. 1350. Flowers rose- 

 coloured. Lamarck's name has been adopted in preference to 

 that of Linnaeus in consequence of its being more expressive of 

 the habit of the plant, and to prevent its being confounded with 

 A. Chinensis. The specimen in the Linnaean herbarium under 

 the name of A. Sinicus is certainly a species of Coron'dla very 

 near C. taria.
