panulato-pateriformis, parvus, extus parce margine densius pilosulus lobis 

 brevibus ovatis obtusis; maturus valde auctus inflato-campanulatus, mem- 

 branaceus, 10-nervius, marginibus introrsum recurvis. Corolla minima, 

 solitarie ex calice amplo exsertula, limbi marginibus longe villosellis. 

 Nuculae sordide atro brunneae. 



Planta 20—25 cm alta. Caulis internodia 5 ... 4 ... 3,5 ... 3 . . 

 etc. cm longa. Poliorum lamina superficie 2 — 5 X 1—1,4 cm, crenae 

 1 — 1,5 mm altae et eorum culmina 2—3 mm distantia, petiolus 3—8 mm 

 longus. Spicastra terminalia sect. long, ad 3 X 1,3 cm, lateralia minora; 

 bracteae 3 — 4 mm longae. Calix sub anthesi 3,5 mm altus. ore 3,5 mm 

 latus, lobis vix 0,5 mm altis; maturus sect. long. 5X3 mm. Corolla 

 calicis os 2 mm excedens, limbo infra 1 mm lato. Nuculae sect. long. 

 2 X 1,5 mm. 



Genus novum distinctissimum in honorem cl. Ove Paulsenii nomina- 

 vimus. Pertinet ad tribum Stachyoideae-Pogostemoneae, sed cum nullo 

 genere hujus tribus confundi potest. Ab omnibus enim diftert calice sub 

 anthesi ample campanulato-pateriformi, maturitate campanulatim inflato- 

 aucto, corolla minima subaequali tubo exsertulo et limbo brevissimo, 

 staminibus 4 aequalibus, styli ramis apice globoso-incrassatis. Habitu 

 Elsholtziae ut et nuculis rugosis accedit, sed spicastrorum non dorsiven- 

 tralium bracteae nullo modo imbricatae, et calicis corollaeque caracteres 

 omnino diversi. A Pogostemone calicis corollaeque indole ut et stylo etiam 

 longe differt.
