Whytockia, W. W. Sm. Genus novum Gesneracearum. 



Genus Stawrantherae, Benth. valde affine. Ab illo genere 

 imprimis corollae ecalcaratae structura, stylo longo gracili, 

 ovario subbiloculari recedit. Forma structuraque floris 

 Didymocarpum et Chiritatn suggerunt. 



Herba parum ramosa. Folia ampla, membranacea, op- 

 posita, altero nano stipuliformi. Flores satis magni, rosei, 

 laxe racemoso-cymosi. Calyx late campanulatus mem- 

 branaceus, 5-fidus, sinubus baud plicatis, segmentis subae- 

 qualibus. Corolla tubuloso-ventricosa, tubo baud calcarato; 

 limbus 2 - labiatus, labio postico bifido, antico 3 - fido. 

 Stamina perfecta 4, inclusa, basi corollae inserta ; antherae 

 cohaerentes, loculis divergentibus confluentibus. Discus 

 angustus annularis. Ovarium liberum, ut videtur bilocu- 

 lare ; stylus satis longus, gracilis, stigmate bilobato ; pla- 

 centae undique ovuliferae. Capsula depresso-globosa vix 

 exserta, membranacea, in specirainibus nostris irregulariter 

 rumpenda sed fortasse obscure bivalvatim dehiscens. 

 Semina permulta oblonga.
