The fine old stove plant of which a specimen is here represented calls for very 
few remarks at our hands. Some records speak of it as having been introduced 
more than twenty years since, and it may have been a cultivated plant in England 
as far back as that date ; but we look upon the present race of plants as modern 
arrivals, from St. Martha, New Granada, South America, to the Boyal Botanical, 
Kew, or Sion House Gardens ; from thence it has found its way into many 
collections. Messrs. Knight and Perry's produced flowering specimens, which 
enabled us, last summer, to prepare the present drawing. 
Ruellia macrophylla succeeds under culture when grown in the soil and favoured 
with the treatment stove plants usually receive. It is a free-growing and abundant- 
flowering species, quickly attaining goodly dimensions ; has ample foliage, flowers a 
considerable length of time in summer, propagates easily by cuttings, and, we doubt 
not, can be made to do so by seeds likewise. Liberally grown, large specimens 
display the character of our subject to the greatest advantage ; but small ones also 
flower, and when doing so are worthy of even choice collections. 
Dr. Lindley, publishing R. macrophylla last year, wrote of members of this and 
allied genera thus : — " It should be an instruction to all persons sending home 
South American seeds, not to forget the fine species of Acanthads with which that 
part of the world abounds ; for although many are but weeds, yet others are quite 
as striking for their beauty as this and the Justicias, Aphelandras, &c, already in
