Leaflets long-acuminate ; panicle-branches slender, 

 with few-flowered cymules ; corolla-tube without a 

 ring of hairs within 



Leaflets short-acuminate ; panicle-branches stout, 

 with many-flowered cymules ; corolla-tube with a

4. V. Clarkeaiia. 



5. V. coriacea. 



6. V. siamica. 



7. V. pubescens. 



8. V. heterophylla. 



9. V. sumatrana 

 var. urceolata. 



10. V. pteropoda. 



11. V. per-alata. 



12. V. glabrata. 



13. V. longisepala. 



14. V. vestita. 



15. V. gamosepala. 



We have not maintained Clarke's subgenus Glossocaltx because the species 

 V. gamosepala, for which it was established, is so very nearly allied to V. longisepala 

 and V. vestita that, if any subgenus were necessary, it ought to be one which would 

 include these three, so different in inflorescence and fruit from the rest of the genus, 

 and closely allied to Premna and Gmelina.
