glabrous, branched; leaves reniform, concave, glabrous, but 
fringed, on long petioles; spikes prismatic, axillary, tetragonal ; 
calyx 5-cleft, shining, pilose, 6-nerved: the 3 upper segments

Native of China, about Nankin. Dentidia Nankinénsis, Lour. 
coch. p. 369. Plant brownish purple. Anthers 2-lobed. Stig- 
ma acute, bifid. Aspect of plant elegant, with the scent and 
colour of Melissa crética ; but the leaves, spikes, calyx, and 
corolla are different. Perhaps a species of Anisochilus, or 
ZEollánthus.

Lin. syst. Didynamia, Gymnospérmia. Calyx ovate-cam- 
panulate, erect, or often declinate or reflexed in the fructiferous 
state: throat naked, or hispid, 5-toothed: upper tooth ovate, 
membranous, with the margins rarely decurrent: lower teeth 
narrower, all acute, or the lateral ones are ovate-truncate ; the 
two lowermost ones often combined. Corolla with an exserted, 
defracted tube, an inflated or equal throat, and a bilabiate 
limb: upper lip short, bluntly 3-4-cleft : lower one entire, 
elongated, concave, usually boat-shaped, involving the genitals. 
Stamens 4, declinate: lower ones the longest; filaments tooth- 
less, connected at the base into a tube, which sheaths the style ; 
anthers ovate, reniform, with confluent cells. Style subulate at 
apex, equally bifid; stigmas subterminal. Achenia roundish, 
compressed, smooth.—Herbs annual or perennial at the base, 
rarely suffruticose. Whorls usually 6-flowered, but often many- 
flowered, sometimes very dense, and sometimes loose, cyme- 
formed. Floral leaves bractea-formed, more or less comose 
at the tops of the racemes before florescence, but afterwards 
deciduous, rarely subpersistent, reflexed. The monadelphous 
stamens distinguish this genus from all other of the order.
