pilose inside, somewhat enlarged at the throat ; limb 2-lipped ; 
upper lip short or very short, subentire, emarginate or 2-fid, some- 
times truncate; lower lip elongated, spreading, 3-lobed; median 
lobe largest, emarginate or 2-fid. Stamens 4, didynamous (the lower 
pair longer), usually exserted from the upper lip; anthers 2-celled ; 
cells divergent or divaricate, finally confluent. Disk equal or often 
produced in front. Ovary shortly 4-lobed nearly to the middle ; 
style 2-fid; lobes subulate, subequal. Nutlets obovoid, reticulate- 
ea Nee attached by a broad lateral areole which extends beyond the

decumbent or stoloniferous; leaves often coarsely toothed, sometimes incised, 
rarely quite entire ; floral leaves similar or the upper (sometimes all) reduced to 
bracts ; whorls 2- to many-flowered, axillary or in dense or interrupted terminal
