The description of the plant and flowei is taken from a living spicemen 

 cultivated in the Buitenzorg Gardens, flowering January 1919, of the fruit 

 from alcohol material from the same spécimen - It may be possible that 

 this is the Buitenzorg plant referred by Engler to L. crassifolia £/î^/. forma 

 latisecta when still in a young state. L. crassifolia En<yl., however, differs 

 in having the spalhe with the lamina long-linear, ± 6 times as long as 

 the tube whilst in this species the lamina is elongate-conoid or -ovate, as 

 long as the tube or somewhat longer.
