" 5. Satyrium chrysostachyum. It failed to tiower here this 

 year, though in soil brought from the Cape, (fine black sand rich 

 in vegetable particles,) as, I apprehend from, inattention to water- 

 ing the roots. They frequent very moist places, even swamps, 

 (i.e. in the wet season,) though perfectly dry at the end of the hot 

 months, and seem to require moisture so long as the flower con- 

 tinues, as well as increased heat. However, when dormant, per- 

 fect siccity is requisite, no doubt, for these as for the rest. 



" 5. Disa graminifoUa. (Herschelia ccE/estis, Lindl.» It is of 

 delicate management. Even at the Cape, I could hardly get it to 

 bear transporting from the bulrushy sand, where it luxuriates, 

 among an infinity of harsh sour grasses, and rush-like vegeta- 

 tion, about IS inches or 2 feet high. Yet I have had one 

 flower-stalk from it this summer It is a ven.- beautiful and sin- 

 gular looking flower. It seems to pine for want of its natural 

 companions, and except in soil taken from such localities will 

 probably not thrive. 



" 7. Disa grandijiora. It grows on, or near the summit of the 

 Table Mountain, where the temperature is occasioually and 

 occasionally also 96**^, (these were the minimum and maximum 

 of a self registering thermometer, I left there for three years). 

 Its habitat is on the margin of pools of standing water, the 

 drainage of the boggy slopes of the mountain, wherein its roots 

 are immersed. These are dry or nearly so in summer. In such 

 localities, it is of course frequently involved in the dense mist 

 of the clouds, which even in the hottest months, often cover 

 the whole summit of the mountain, for a week or a fortnight un- 

 interruptedly. It languished for two years by a pond in mv 

 garden, but would, I think, have grown accustomed to the change. 

 I presume a moderately warm, habitually damp atmosphere 

 would suit it. '
