specimens has shown that the plant is more nearly allied 

 to Albuca than to Drimia or to Ornithogalum, but it 

 differs in having the inner perianth-segments erect and 

 shorter than the outer, and differs further so greatly in 

 the structure of the filaments that it seems desirable to 

 accord it the position of a distinct genus, ThurantJt&s, a 

 name based on the disposition of the lower portions of 

 the filaments, which are coloured like the perianth, are 

 outcuived for about a quadrant and connivent above, 

 thus leaving interspaces like the longitudinal openings of 

 a lantern. The portions of the filaments surmountir g 

 this lantern are cylindric, w^hite, and erect round the 

 columnar style. The colour of the perianth-segments 

 appears to vaiy considerably ; in field-notes it is given 

 'red-brown,' 'yellow-green,'"' brown with a red band.' 

 The treatment most suitable for South African species 

 of Ornithogalum appears to be equally appropriate to 

 Tlauanthos macranthum which, Mr. Lynch informs us, 

 though it has thriven satisfactorily at Cambridge, sending 

 up fresh young leaves, has not flowered since it did so in 

 1913.
