8. Z. retrofractum, Thunb., Fl. Cap., p. 545. 



Upper : Common on lower slopes above Loeriesfontein, 4854 

 Great Namaqualand : Eiver-bed at Dalbaigabis, 4317. Narnaqua- 

 land : Near Klipplaat, 3483. Doornport Ravine, 6128. Common 

 on slopes at Eenriet, 3098. Stinkfontein, 5621. Alewyn's Fontein, 

 3480. 



In numbers 3483, 3480, 3098, and 6128 the capsule is very 

 narrowly winged, and appears to be very different from the capsule 

 of 4854 and 4317, which has 5 broad wings as described by Sonder 

 in Fl. Cap., vol. i. On a specimen collected by Mr. Burtt-Davy, 

 however, there are both broad- and narrow-winged capsules.
