Ill MESO'NA vfrom /MOBC, mesas, middle; so called be- 

 cause the genus was supposed by the author to be interme- 

 diate between the genus Ocymum and Sculellaria.) Blum, bijdr. 

 p. 838. Benth. lab. p. 22. 



LIN. SYST. Didynamia, Gymnatpermia. Calyx bilabiate : 

 upper lip divided : lower one small, at length inflexed. Upper 

 lip of corolla arched : lower one longer, undivided. Stamens 

 didynamous, declinate ; of these the two shorter are appendicu- 

 late at the base; anthers 1 -celled, beardless. A genus inter- 

 mediate between O'cyntum and Scutellaria, ex Blum. 1. c. This 

 genus is nearly allied to Geniosporum, but differs in the shorter 

 stamens being appendiculate at the base ; and from O'cymttm 

 in the superior lip of calyx being divided, and in the inflores- 

 cence, ex Benth. 



1 M. PALUSTRIS (Blum. I.e.) li.? S. Native of Java, in 

 marshes about Buitenzorg. Herb scentless. Leaves ovate- 

 oblong, toothed, wrinkled, rather pilose. Flowers densely and 

 verticillately spiked ; whorls bracteate ; pedicles fascicled.

IV. ACROCEPHALUS (from orpoc, akros, the highest; 

 and ciyaXrj, kephalt, a head ; in allusion to the flowers being 

 disposed in small, dense, terminal, imbricate heads.) Benth. in 

 hot. reg. vol. 15. lab. p. 23. Ocymum species, Lin. and 

 other authors. 



Lix. iYr-i. Didynamia, Gymnospermia. Calyx ovate in the 

 floriferous state, but elongated in the fructiferous state, tubular, 

 gibbous at the base, bilabiate : upper lip entire, flattish : lower 

 lip entire, or 4-toothed ; throat naked inside. Corolla about 

 equal in height to the calyx, sub-bilabiate : upper lip 4-toothed : 

 lower one entire ; lobes all nearly equal. Stamens 4, declinate ; 

 filaments free, toothless ; anthers ovate-renifonn, with confluent 

 cells. Style shortly bifid at apex ; lower lobe a little dilated, 

 flattened ; stigmas submarginal. Achenia glabrous, smooth. 

 Herbs. Flowers small, disposed in densely imbricate, terminal, 

 almost globose heads. This genus differs from O'cymum, Genios- 

 porum and Moschosma by the form of the calyx, and more espe- 



cially by the inflorescence. The form of the corolla distinguishes 

 it from all other genera of the tribe Ocymoideae.

 rated : floral ones 2-4 under each bead, and longer than it, 

 sessile. Heads ovate, pedunculate, or sessile.

 well as the under sides of the leaves. Floral leaves 2-4 under 

 each head.

Lix. STST. Didynamia, Gymnospermia. Calyx ovate, 5- 

 toothed : upper tooth the largest, with the margins not decur- 

 rent : lower teeth nearly equal, and somewhat declinate after 

 florescence ; throat naked inside. Corolla with an inclosed 

 tube, and a sub-bilabiate limb ; upper lip shortly quadrifid : 

 lower one quite entire, flattish ; lobes all nearly equal. Sta- 

 mens 4, declinate ; filaments free, toothless ; anthers ovate- 

 reniform, with confluent cells. Style clavately capitate, and 

 shortly bifid at apex ; stigmas minute. Achenia ovate, com- 

 pressed, smooth. Herbs. Whorls few-flowered, secund. 

 loosely racemose ; racemes axillary, subpanicled. The clavate 

 style and form of the calyx separates this genus from the pre- 

 ceding genera. Flowers very minute.
