Cehon, Walker No. 332. 



Small, woody, procumbent, with the habit of Thyme. Leaves J-f in., ovate-sub- 

 acute, nearly sessile, shortly setose on both surfaces, drying black. Calyx-tube and 

 teeth with stalked stellate rufous hairs ; teeth suberect, aubpersistent. — ^Mr. Thwaites 

 treats this also as a var. of 0. cuputaris, and it has all the appearance of being an 

 alpine form of that plant. 



4. O. Rheedii, Thwaites Enum. p. 104; stiffly shrubby, scabrous, leaves 

 rigid 3-nerved harshly scabrous on both surfaces or glabrous "above, flowers 1-4 

 clustered, calyx-tube with adpressed simple hairs, teeth long-lanceolate with 

 erect simple hairs. 



Ceyxon; Wight, Walker, Thwaites. 



Small, woody, much branched. Leaves 1 in., elliptic or oblong, narrowed at both 

 ends ; petiole | in. Petals f in., pale purple. Fruit |-J in. broad, ovoid, truncate. — 

 Mr. Thwaites states the flowers 4-fid, as they are in all the Kew examples ; Triana 

 puts the species in his section Asterostoma with 5-fid flowers without explanation. 

 The plant differs from Asterostoma in the smaller flowers and (what is of more 

 importance) in the anthers which are truncate at top and altogether those of section 

 Amblyanthera. 



Sect. n. Genuinae. P/oicers normally 4-fld, not large. Ci%^ campanu- 

 late, not produced or produced into a short neck in the fruit. Anthers beakfed.

 linear suddenly narrowed at the base, flowers capitate, fruiting calyx-tube with 

 few (or none) adpressed pectinate scales soon smooth shining. Ltmr. Fl. Cochinch^

HmiAiATA Teeai from KtmAON to Bhotan, up to 4000 ft. alt. Abundant in 

 NoETH and East Bbngai, including Assam and Khasia and thence to Singapobe. Also 

 in Chota Naopore, alt 2000-4000 ft. — Disteib. Through China and Malaya to Japan 

 and North Australia. 



Stems 2 ft., branches descending, tetragonous, with adpressed hairs. Leaves com- 

 monly 2 in., narrow-oblong, sometimes 6 in., long-linear, in the Parasnath variety ellip- 

 tic-oblong from a subcordate base, acute, 3-5-nerved, hairy on both surfaces ; petiole 

 less than i in. Bracts ovate, on the back glabrous or with a few scattered hairs. 

 &^a;-tee3i lanceolate, glabroi*, not keeled on the back, ciliate on the margin ; hairs 

 at their tips not spreading stellate. Petals ^ in., mauve. Anthers with a beak about 

 half their own length. Bristles on the apex of the ovary about 1 6. Fruit ^ in. wide 

 (or much larger in the Parasnath variety), ovoid, with a short neck, often glabrous, 

 scimetimes with few or several bristles, calyx- limb never persistent ; in the Pegu ex- 

 amples the neck is much prolonged widened at the top. — The figure Bot. Mag. t. 4026 

 rejected by Bentbam and Triana, admitted by Naudm, is the true plant : the anther 

 is drawn too long-beaked for 0. oetomdra to which Triana refers it, and the accom- 

 panying text states the anthers to be "longish beaked"; also the plant is stated to
