44 removed by a deeper division from the rest, the calycine segments are more membranous and foliaceous, and the whole plant more or less hairy; its berry is very similar to that of P. arenaria, being large and apparently purple. Unless in specimens furnished with tolerably ripe fruit, it is difficult to recognise the genus Pratia, the character of the corolla being common to other true Lobeliace&aelig;, as is also that of the calyx, except that some of the species possess additional small lobes at the base of one or more of the segments. The bracts on the peduncles are also only occasionally present, and their situation is very variable.

As this plant has been found by Mr. Bidwill on Tongariro, it is probably not uncommon in the alpine
