rectus, orthotropus, albus. CorvLEDoNEs semiovatæ, obtusæ, vix longitudine radicule inferze.— Brown. 
Gratiola involucrata, Roxb. Flor. Ind. vol. 1. p. 138, certainly belongs to this genus, and is perhaps not specifically 
different from the plant here described. But a second species, discovered in Java by Dr. Horsfield in 1815, may 
be readily distinguished by the following character: Arna (Horsfeldii) folio unico sessili, caulem simplicissimum 
terminante, pedunculo solitario pluribusve seriatis.— Brown. 
For the preceding account of this plant, as well as for the beautiful drawing of the late Mr. Ferdinand Bauer, 
from which the accompanying Plate has been engraved, I am indebted to Dr. Brown, to whom I offer my warmest 
thanks. He has likewise permitted me to dedicate this very curious genus to my highly esteemed friend Arthur 
Aikin, Esq., Fellow of the Linnean and Geological Societies, and Secretary to the Society for the Encouragement of 
Arts, Manufactures, and Commerce; a member of a family greatly known to fame, through his father Dr. Aikin, 
his aunt Mrs. Barbauld, and his sister Miss Lucy Aikin, the distinguished authoress of the * Court of Elizabeth, 
and of James the First”; himself not less eminent as a man of science, by his almost universal acquirements and 
his numerous valuable contributions to the common store of knowledge, than by the great suavity and urbanity of his 
manners, and the readiness with which he at all times communicates his varied knowledge.
