the plants were large and robust, being kept continually moist 

 by the spray from the falls. Here it grew among the boulders 

 and loose stones which have accumulated at the foot of the 

 falls.

That a species native to the Hawaiian Islands should be 

 identical with an African species, is hardly tenable. Hille- 

 brand, after noting some difference between the Hawaiian plant 

 and Weddell's B. stipularis, thinks "it is probable that two dis- 

 tinct species lie concealed in the present one {stipularis), and 

 that thus the difficulty of explaining the occurrence of only one 

 species in two limited areas which are removed, from each other 

 by half the circumference of the globe, will find an easy solu- 

 tion." Nevertheless, he did not attempt a solution, which i& 

 certainly easy, for in Urtica grandis H. & A., we have a per- 

 fectly valid name to apply to the Hawaiian plant On Oahu, it 

 is credited as occurring only on Mt. Kaala, of the Waianae 

 range. On Konahuanui, back of Honolulu, I obtained speci- 

 mens at an elevation of about 2500 feet (2906), early in Novem- 

 ber. This is the broad-leaved, apparently typical form. On 

 Kauai, specimens of the variety gamma of Hillebrand were col- 

 lected at Hanapepe Falls, where it is rather plentiful. This form 

 (2436), which is quite constant on Kauai, was again observed 

 in a branch cafion of the Hanapepe, at an elevation of about 

 1500 feet, and also on Kaholuamano, above Waimea, at an ele- 

 vation of 4000 feet. It differs from the Oahu plant in being 

 taller and more slender, with narrower and more pointed leaves, 

 which bear but few scattered pilose hairs on the midveins, in- 

 stead of being markedly hairy on all of the veins. The upper 

 face, too, is merely granular, instead of pilose.

Hillebrand says that this species occurs "on all islands, on 



dry slopes of the lower regions." My specimens were collected 



on Kaholuamano, above Waimea, Kauai, at an elevation of 4000
