 alt. 3,250 feet (Sim, 8816). 



General distribution : Cape Province, Transvaal, Zululand. 



This specimen was growing on stones ; a very unusual habitat 

 for such a characteristically corticolous plant. 



Erpodium hanningtonii Mitt. — Zimbabwe, alt. 3,000 feet 

 (Sim, 8801); on rock, Matopos (Wager, 899); Victoria Falls 

 (Wager, 907) ; rarely found elsewhere than on trees.

General distribution : Transvaal, Natal, Portuguese East 

 Africa. 



Braunia secunda (Hook.) B. and S. — In numerous localities. 

 Frequent about the Zimbabwe Ruins; a distinctly xerophytic type. 

 Granite boulders, Bulawayo (Sadler, 383, in herb. G. Webster); 

 Makoni (Eyles, 835); Rhodes' Grave, Matopos, alt, 5,000 feet 

 (Sim, 8871), etc.; Salisbury, alt. 4,900 feet (Eyles, 1572). 



Several of the gatherings are referable to the forma longipila, 

 one from Macheke, on granite rock, alt, 5,000 feet (Eyles, 1993) 

 being a very extreme condition ; some of the branches having the 

 leaf acumen hyaline quite as in ILedwigia albicans. Many of the 

 gatherings were in fruit. "Tlypnum sp." Eyles [8] is this species 

 (Eyles, 1026). 



General distribution : South and Central Africa, India,
