By Spencer le M. Moore, B.Sc, F.L.S.* 



(Plate 544.) 



1. Genera nova duo. 



Capitanopsis, 



Labiatarum e tribu Ocimoidearum genus novum. 



Calyx brevissime bilabiatus, fructifer auctus necnon papyraceus 

 reticulatusque, labio antico unclulato-4-clentato quam posticum 

 integrum multo majori. Corollge tubus valde abbreviatus, in 

 fauces obliquas subcylindricas expansus ; limbus bilabiatus, labio 

 postico parvo bilobo labii antici lobis lateralibus latis lobo inter- 

 medio concavo patente. Stamina 4, didynama, declinata, breviter 

 exserta; filamenta libera; anthers uniloculares. Discus perspicuus, 

 breviter lobatus. Stylus apice bifidus. Nuculae ovoideie, sericeae. 

 — Verisimiliter frutex nisi suffrutex parvifolius. Verticillastri 

 circa 6-flori, ramulos terminantes. Corollae dilute roseae. 



C. Cloiselii, sp. unica. Foliis breviter petiolatis oblongis 

 obtusis basi paullo angustatis integris papyraceis supra subtiliter 

 pubescentibus subtus minute griseo-tomentellis, infiorescentiae 

 axi ut pedicelli tomentello, calycis tubo campanulato extus 

 tomentello labio postico suborbiculari labii antici dentibus 

 rotundatis, corollae extus pubescentis labii postici lobis obovatis 

 obtusissimis labii antici lobis lateralibus rotundatis lobo intermedio 

 cymbiformi, stylo exserto complanato glabro. (Tab. 544, lig. 1.) 



Hab. Madagascar, Fort Dauphin ; Chisel, 62. 



Eamuli sat valide corticati, minute pubescentes dein glabri. 

 Folia plerumque 1-5-2 cm. long., 5-6 mm. lat. ; petioli tenues, 

 pubescentes, summum 3 mm. long. Pedicelli saspissime 2-3 mm. 

 long. Calyx tlorescens 4x6 mm., fructescens 7 x 14 mm., hujus 

 labium posticum 4x5 mm., anticum 9 x 10 mm. Corollte tubus 

 summum 3 mm. long., aegre 4 mm. lat. ; fauces 17 x 7 (ipso sub 

 limbo 9) mm. ; labium posticum 3 x 4-75 mm. ; hujus lobi vix 

 3 X 2-5 mm. ; labii antici lobi laterales 3x6 mm., lobus anticus 

 5x3 mm. Filamenta basi dilatata ; antherae 1 mm. long. Stylus 

 15 mm. long. Nuculae (anne maturae ?) -75 mm. long. 



This plant has a calyx much like that of Capitanya, except for 

 the front lobes of the Capitanya calyx being smaller than the rest 

 whereas here it is the hinder lobe which is reduced. The corolla 

 is, however, quite different and closely resembles the corolla of 

 Alvesia, with its relatively small front lobe, thus placing it in the 

 neighbourhood of Plectranthus, while Capitanya is near Ocimum. 

 But though it has the corolla of Alvesia, Capitanopsis has nothing 

 in common, except accrescence, with the equally 2-lipped calyx 

 of the other which becomes a sort of inflated bag as it matures. 

 * The types of species described in this memoii' are in the National Herbarium.
