above, more or less castaneous, quadrangular; leaves for the most 

 part linear-oblong, 5-1 1 cm. long, 5-10 mm. wide, sometimes 2 cm. 

 wide, glabrous, paler below, on both sides glandular-punctate, the 

 margin remotely crenulate, towards the base often recurved, the 

 apex somewhat obtuse to rounded, gradually attenuate at the base 

 into a short margined petiole, the upper decreasing in size, the mid- 

 vein impressed above, prominent underneath, the lateral nerves few, 

 remote, anastomosing before reaching the margin; flowers aggregated 

 into axillary pedunculate heads; peduncles 2.5-4.5 cm. long, rather 

 rigid, from the base somewhat incurved-erect, the lower somewhat 

 shorter than the subtending leaf, the upper longer; bracts oblong- 

 lanceolate, often somewhat dilated aplcally, rather obtuse, longer 

 than the head, paler at the base, ciliate, at maturity strongly reflexed; 

 calyx 4-5 mm. long, tube 2-2.5 mm. long, campanulate, at the base 

 and especially at the middle somewhat incano-pilose, minutely 

 glandular-punctate, the lobes rather erect, lance-subulate, ciliate, 

 about 2.5 mm. long, subequal, at maturity 6-8 mm. long; corolla 

 about 7-9 mm. long, outside sparsely and very shortly spreading- 

 pilose, the upper half bilabiate, the lips very unequal, scarcely ex- 

 panded, the upper lip barely i mm. long, its lobes broadly ovate, 

 apically rounded, the lower lip 3.5-4 mm. long, its median lobe 

 rounded, emarginate, deeply cucullate, the margin minutely erose, 

 the lateral lobes one-half shorter, obliquely ovate, obtuse; stamens 

 inserted on the throat, slightly shorter than the corolla, anthers all 

 fertile, reniform; the style smooth, shortly 2-lobed, the lobes oblong; 

 nutlets about l mm. long, dark brown (almost black), lustrous, oval. 

 Planta suffruticosa, basi verisimiliter perennans, plus minusve i m.

 obtusiusculis vel rotundatis, basi sensim in petiolum breve marginatum

 impresso, subtus prominentibus, nervis lateralibus paucis, remotis,
