97. Acrocephalus. Benth Having, since I gave the character of this genus in 1282 of the 



Register, had opportunities of examining more perfect specimens of two of the species, I have 

 been enabled to ascertain that it belongs rather to the Ocymoidew than to the Menthoidea. The 

 character may be thus amended : — Calyx ovatus, bilabiatus, labio superior! integro, inferior! integro 

 V. qtiadridentato, fructifer tubulosus basi gibbus. Corolla calycem subaequans, bilabiata, labio 

 superiori quadrifido, inferiori integro subplano. Stamina 4, declinata. Filamenta libera, 

 edentula. Anthers ovato-reniformes, loculis confluentibus. Stylus apice breviter bifidus, lobo 

 inferiori subdilatato complanato. Flores dense subgloboso-capitati. 



Species 1. A. capitalus {A. scariosus Benth. supra, fol. 1282; Ocymum capitatum Roth.; 

 O. capitellatum Linn. ?) 2. A. villosus, from Madagascar. 3. A. Blumei {Ocymum acrocephalum 

 Blume). 



98. Anisochilus. Wall. — Calyx ovatus, bilabiatus, labio superiori subintegro, post anthesin 

 deflexo, calycem claudente, inferiori truncato. Corolla tubo exserto refracto, fauce subinflata, 

 bilabiata, labio superiori 3-4-fido, inferiori integro concavo. Stamina 4, declinata. Filamenta 

 liliera, edentula. Antheraj ovato-reniformes, loculis confluentibus. Stylus apice subulatus, 

 a'qualiter bifidus. Flores dense imbricato-spicati. 



Besides the Lavandula camosa Linn, this genus comprehends two or three new East Indian 

 species. 



99. Pycnostachys. Hook Calyx ovatus, subaequalis, dentibus 5 subulato-spinosis. Corolla 



tubo exserto subrecto decliuato, bilabiata, labio superiori quadrifido, inferiori integro concavo. 

 Stamina 4, declinata. Filamenta libera, edentula. Antheraj ovato-reniformes, loculis conflu- 

 entibus. Stylus apice subulatus, a;qualiter bifidus. Verticillastri dense spicati, spicis siraplicibus.

101. Hyptis. Jacq Calyx tubulosus, »qualis, dentibus 5 subulato-aristatis. Corolla tubo 



calycem subaequante, quadrifida, subbilabiata, lobo superiori latiore sa?pius emarginato, lateralibus 

 integerrimis planis, inferiori concavo. Stamina 4, declinata. Filamenta libera, edentula. Antherss 

 ovato-reniformes, loculis confluentibus. Stylus apice suViaequaliter bifidus. Verticillastri nunc 

 dense globoso-capitati, nunc spicati, racemosi, v. paniculati. 



102. Marsypianthus. Mart Calyx campanulatus, membranaceo- inflatus, 5-aristatus. Corolla 



tubo calycem subaequante, quadrifida, subbilabiata, lobo superiori latiore emarginato, lateralibus 

 integerrimis planis, inferiori concavo. Stamina 4, declinata. Filamenta libera, edentula. 

 Anthera; ovato-reniformes, loculis confluentibus. Stylus apice subaequaliter bifidus. Verticillastri 

 dense globoso-capitati.

Barbula. Lour. fl. cochin, belongs to Verhenacem., to which order it appears to me also 

 that Phryma Linn, should be referred. I am totally unacquainted with Vleckia Rafin, and 

 Pheboanthe Tausch, both included by Reichenbach amongst Labiatae in his Conspectus. 



In my characters of Perilla and Elsholtzia, fol. 1282 of the Register, the corolla is erroneously 

 described' as having the odd division above, instead of below. In Colebrookia and Perilla the style 

 is deeply two-cleft ; in the other genera of Menthoidece it is, as in most Labiataj, slightly cleft at 

 the ape.x. 



Elsholtzia paniculata Willd. is a true Pogostemon. The genus Elsholtzia remains, therefore, 

 confined to E. cristata. Perhaps my Aphanochilus might be united to it as a second section. 



To the Menthoideae may be added the following genus, which may be placed immediately before 

 Elsholtzia : 



TelraAenia, Benth Calyx campanulatus, 5-dentatus, dente superiori latiore, intus fauce nuda. 



Corolla tubo brevissimo, campanulata, 5-fida, lobis ovatis subaqualibus. Stamina 4, exserta, 

 distantia. Antherje loculis confluentibus, valvulis reflexis. Ovaria intra glandulas 4 recondita. 



Stylus apice breviter bifidus Species unica Madacascariensis T. fruticosa (Mentha fruticosa, 



Helsing. et Bojer MS. in herb. Hooker). Flores spicati, spiculis racemosis, racemis paniculatis. 



Cunila Linn., which, at fol. 1289 of the Rcf/ister, I placed in the tribe of Synandreae, has two, 

 and sometimes (in C. coccinea Hook.) four distant stamina, with the anthers distinct, bilocular, 

 and parallel-celled ; and therefore should be referred to Sacureineae, where it may be placed imme- 

 diately after Origanum. 



Dr. Hooker's herbarium contains a plant sent by Mr. Elliott from South Carolina, under the 

 name of Ceranthera linearifolia, which forms a very well-marked genus of the same tribe of 

 Satureineae ; although his name cannot be adopted, as Palisot de Beauvois had long since ap]ilied 

 it to a genus of Violaceae. Mr. Elliott's genus may be thus characterised : 



Dicerandra Benth Calyx 10-nervis, tubulosus, bilai>iatus, labio superiori subintegerrimo, 



inferiori bifido, intiis fauce villosa. Corolla tubo exserto inctirvo, bilabiata, labio superiori brevis- 

 sime emarginato, inferiori trifido. Stamina 4, exserta, distantia. Antherae biloculares, loculis 

 divaricatis saccatis apice dehiscentibus, valvula superiori extiis longe cornuta. Stylus apice sub- 

 aequaliter bifidus.
