Labiatae. 



NOSEMA Prain. 



Calyx per anthesin ovatiis, frnctifer tubulosas haud fenestratus, 2- 

 labiafcus, labiis posfcico oblongo integro persistenfce, antico rotundato 

 integro subdeciduo. Corollae tubus cylindricus fauce parum ampliatus ; 

 limbus 2-labiatus, labio postico breviter 3-lobato lobo medio parum 

 latiore emarginato, antico paullo breviore oblongo integro concavo. 

 Stamina 4 declinata, filamentis liberis, posticis basi dente auctis : 

 antherae confluentia 1-loculares explanatae. Discus antice vix tumens. 

 Stylus apice breviter bifidus lobo antico longiore. Nuculae ovoideae, 

 laeves. — Herbae erectae. Verticillastri in capitula terminalia 

 globosa vel dense cylindracea conferta. Plores parvuli. Species 3-4, 

 Monsunenses. 



The genus now described is most nearly allied to the genus Mesona Bl., the two 

 agreeing in the spurred character of the posterior filaments. To the courtesy and 

 kindness of Mr. C. B. Clarke, P.R.S., to whom he had submitted for an expression 

 of opinion the proposed new genus, the writer is indebted for the subjoined concise 

 and effective diagnosis. 



I. Mesona Blume.—Galyx with 2 membranous coloured lips, the upper 3-fid, 

 the lower entire. fw/?orescewce interrupted ; fruiting calyces fenestrate with trans- 

 verse bars, held up on pedicels. 



II. NosEMA Prain. — Galyis with 2 membranous coloured lips, both undivided. 

 Inflorescence dense; fruiting calyces not transversely barred, subsessile, the pedicels 

 finally buried in the agglomerated calyces. 



1. NosEMA CAPITATUM Prain. A brancbing herb over 15 in. in 

 height; stems 4-grooved, with rounded angles, beset with adpressed 

 reflexed hairs. Leaves opposite, narrowly oblong, tapering from below 

 the middle to the cuneate base with entire margin, margin elsewhere 

 finely crenate, apex obtuse or subacute ; chartaceous, pubescent on both 

 surfaces, but especially on the nerves beneath ; lateral nerves 9-10 pairs* 

 oblique, straight, rather close-set, conspicuous; length 2-2*5 in., width 

 •6-*75 in. ; petiole pubescent '25 in. long. Flowers in dense terminal 

 capitula '25-2 iu. long; calyx in fruit 15 in. long, upper lip half as long 

 as tube, lower lip less than half as long as upper and soon deciduous ; 

 tube not fenestrately transversely barred, densely tawny- tomentose with 

 spreading hairs ; corolla half as long again as calyx, both lips sparsely 

 pubescent externally; stamens exserted, declinate, the posterior pair 

 inserted higher up than the anterior and strongly toothed just above their 

 bases. Nutlets all ripening, ovoid, glabrous, smooth. 



Indo-CHINA : Siam ; Kanboerie, Teysmann ! 



In Herb. Kew. there are two gatherings from Java, by Junghuhn (nn. 8, 51), of 

 which the writer has seen ripe fruits. As to calyx and nutlets they agree exactly
