An excedinyly liaiulsome species when in full hlnnni; the flowers are usually 

 pink. The species is a nionocarp, as well as some of our true Lo])elias. Prof. 

 A. 8. Ilitclicock collected it for the first time on the island of Lanai. It is not 

 unconnnon in the mountains of Oahu, especially on the upper slopes of the ranges 

 back of Honolulu. 



The flowering' habit of this species is quite different from that of the Ha- 

 waiian true Lobelias; the dowering spikes number usually nine and are arrangeil 

 horizontally like the spokes of a wheel; in this it resembles Liibclia rosea from 

 India, which has a similar intioreseenee. As the spikes reach nuiturity the 

 cluster oi' leaves at the apex of the stem drops off and when fully mature the 

 spikes alone remain without any leaves at all.

This variety is (juitc snudler than the species and ditt'ei's from it in the 

 strongly archetl scarlet-jiurple smaller corollas, the fewer racemes, short leaves 

 with red venation, and black stems. The branching of the inflorescence is some- 

 what different from that of the species; the brandies are fewer, semi-erect, and 

 widely scjiarated. 



Wawra's specimen no. 2190 served Dr. Zahlln-uckner as the type of his Trmia- 

 iocarpus ^^ Trematolobelia and not the species from Oahu or the other islands; 

 the species does not occur on Kauai. It is associated with Lobelia Kauaensis,
