harrow and long, so that fertilisation can only be effected^ by a minute insect, and 

 the flowers only remain open for half the day, being completely closed before the 

 evening The late W. T. Gerrard, who first collected the plant, noted that the 

 flowers were unisexual, and it was afterwards named Kaempferia natalensis, by 

 Schlechter & Schum, and they said that if male flowers had been found they pro- 

 posed to "give it the dignity of a new genus," for which they suggested the name 

 Siphonochilus. That name we have therefore retained, though no male flowers 

 have been seen, female and hermaphrodite only.
