298 D. Prain — Some additional species of Labiatse. [No. 4, 



Concan from the Manipur plant. This species therefore repeats the 

 detached distribution exhibited by Pogostemon paniculatus, which occurs 

 in Lower Burma and in the Western Deccan but apparently nowhere 

 between. The principal difference between P. purptirascens and P. 

 parviflorus consists in the former having longer calyx teeth and larger 

 flowers than the latter. 



24 b. Pogostemon Wattii C. B. Clarice • simple or branched, puber- 

 ulous with reflexed hairs, leaves elliptic-ovate acuminate, dentate except 

 the base, lamina decurrent on the long petiole, nerves densely elsewhere 

 sparingly puberulous above, glabrous except the nerves beneath, spikes 

 narrow terminal and axillary sparingly softly hairy, whorls close set or 

 shortly interrupted, bracts minute linear, calyx distinctly pedicelled, 

 tubular, hirsute externally on the nerves, teeth triangular the 2 lower 

 slightly exceeding the 3 upper, corolla tube distinctly exserted, lobes 

 puberulous, filaments sparingly puberulous, nutlets on a short gyn- 

 ophore. — Pogostemon Wattii G. B. Clarice, Jour.- Linn. 8oc. xxv, 59. 



Manipoe ; Kassome range, 3 — 4000 feet ; near Kongal Thana, 3500, 

 Watt nn. 5079, 6613. Assam ; Naga Hills, at Kohima, 4750, Clarke. 



Stems 40 — 60 cm. rather slender terete, petioles 3 — 4 cm., lamhuB 

 6 — 9 cm. long 3 — 5 cm. wide, spikes 6 — 11 cm. long under 1 cm. wide, 

 pedicels 3 mm., calyx 5 mm. lower teeth 1 mm., corolla 7 mm. long tube 

 annulate within (the annulus of star-like processes and incomplete 

 behind where the style is lodged), stigma shortly 2-fid, nutlets 1 mm., 

 gynophore 0'5 mm. 



A very distinct species. 



13. DYSOPHYLLA Blume. 



* Calyx tube terete or obscurely angled. 



f Leaves opposite. 



3 b. Dysophylla Andersoni Prain; dwarf, stout, erect, stems and 

 leaves on both surfaces adpressed pubescent, leaves sessile lanceolate 

 or oblong-lanceolate acute quite entire, spikes short, stout, softly tomen- 

 tose, calyx short glabrescent, teeth bluntly triangular half as long as 

 tube. 



Sikkim ; Terai, Dr. T. Anderson. 



Stems only 8 — 15 cm. branched, branches erect stoutish woody, 

 leaves 3 — 4 cm. long, 1 cm. wide, spikes 15 — 20 mm. long 10 mm. 

 wide, sessile, whorls confluent, calyx in fruit 2 mm. long teeth erect, 

 teeth hirsute, tube glabrous externally, corolla tube included, lobes 

 sparingly hairy, nutlets globose, smooth, shining, red-brown not tri- 

 gonous. 



Allied to D, rngosa and to D. salicifolia but very distinct from both.
