Kunze, and following him, all succeeding authors have pronounced that 

 the admirable figure of Gymnogramme " cordata," of Dr. Greville in Ic. Til., 

 is not the Grammitis cordata of Swartz ; but they refer it to the G. Capensis 

 of Sprengel. We maintain, that it perfectly accords with all the essential 

 characters and full descriptions of the illustrious Swede : but it ill accords 

 with what Kunze figures and describes as the G. Capensis ; nevertheless, 

 we are quite willing to declare our opinion that the two are varieties of each 

 other, for we can trace them through their several stages in our Herbarium, 

 in the following forms or varieties. 1. Pinnata; pinnis oblongis subin- 

 tegerrimis. Ceteraoh Capensis, Kze. in Analect Pterid.p. 13. t. 8. Fee, Gen. 

 Fil. Tab. 30. /. 4. (one pinna slightly pinnaiifid) '. 2. Pinnato-pinnatifia ; 

 pinnis cordatis profunde pinnatifidis. Grammitis cordata, Sw. I. c. and Gym- 

 nogramme cordata, Hook, et Grev. I. c. 3. Subbipinnata; pinnis angusto- 

 oblongis profunde pinnatifidis pinnatisque. Gymnogramme Capensis, Spr. 

 in Zeyh. PI. Cap. (Herb. Nostr.) Kze. in Linnma, &.p. 183. Ceterach Capensis, 

 Fee, Gen. Fil. Tab. 30./. 3. (et Tab. Nostr. VII;. I may add, a 4th state, or a 

 subvariety of the latter. 4. Nudinscula j frondibus parce paleaceis, squamis 

 minoribus subintegerrimis. Gymnogramme Namaquensis, Pappe and Bawson,
