This is allied to L. oleraceum, but can be readily distinguished by the slender often 
prostrate habit, the long petioles of the radical leaves, their crenate margins, and by the 
notched pods. My specimens from the north of the Manukau Harbour are suberect ; 
Mr. Kirk’s are mostly prostrate.

_ This appears to be an exceedingly local plant, and is fast becoming extinct in the 
tew habitats at present known. It is weil characterized by the procumbent habit, 
.ateral racemes, and diandrous flowers.
