Ruellia Infundibuliformis, Roxb. MSS. 
This shrub comes much nearer the frutescent Acanthi of Linné than any Ruellia in the struc« 
ture of the flower ; but it differs so materially: even from them, as to constitute a new genus. 
I find from Dr. Roxburgh’s Manuscripts, that it is common in the Pagoda Gardens of Bengal, 
where it grows to a pretty large size, flowering all the year round. The stem is round, 
jointed, and finely pubescent with opposite branches. Petioles jointed at the base. Flowers 
in terminal spikes. Bractes ending in a sharp bristle, though the leaves are obtuse, Corolla 
of a dull orange colour: Tube very slender, dilated at the base, where it is smooth; from 
thence pubescent especially on the inside below the anthers, and somewhat angular: middle 
segment of the Limb narrowest, Anthers curiously fringed. Pericarpiuim swelled at the base _ 
into a round nectary, Communicated by the Right Hon. Charles Greville,
