the limits usually prescribed for a specific phrase. It 13 

 therefore no wonder that much difficulty should occur in ascer- 

 taining many of the species, without the aid of either figure or 

 authentic specimen ; for nothing can be determined by the 

 figure given us by Jacquin, who first established the species, 

 and there does not appear to have been any specimen of it in 

 his herbarium. We have reason to believe that our plant is 

 the eustachiana of the Hortus Kewensis, and being figured 

 under this name in the Botanical Register, we do not hesitate 

 to adopt it, though we cannot but entertain doubts whether 

 the species defined by Vahl be the same. 



The opportunity afforded us of examining the herbarium 

 of Sir Joseph Banks has not produced the usual conviction 

 in our minds. Dried specimens of many of the species of 

 Justicia are, from their difficult preservation, less satisfactory 

 than usual ; and from an examination of these, we should 

 hesitate between sphcerosperma and eustachiana, or perhaps 

 should have been induced to have rather referred our plant 

 to the former, but that Mr. Brown had examined the anthera 

 of both, and thought that those of the latter agreed in being 

 unilocular, whilst those of the other were bilocular. 



Several species of Justicia of Vahl have, chiefly from this 

 character of unilocular anthers, been separated into a distinct 

 genus by Mr. Brown, in his Prodromus Florae Nova? Hol- 

 jandiffi, page 474, under the name of Hypoestes, which, as 

 he observes, had been long before proposed by the late Dr. 

 Solander* : to this genus we suppose that the Justicia 

 eustachiana here figured must be referred. It should be 

 observed, however; that both Jacquin and Vahl refer their 

 plant to the section of Diantherce. 



Our drawing was taken several years ago from a fine 

 specimen that flowered in the month of April, in the stove of 

 the late -Right Hon. Charles Greville, at Paddington. Mr. 

 Whitley's plant, figured in the Botanical Register, blossomed 

 m June ; m the Hortus Kewensis, August and September are 

 stated as its flowering months. 



A straggling growing shrub; native of St. Eustatia and 

 iUartimco ; propagated by cuttings ; cultivated in the stove.
