816 MINNESOTA BOTANICAL STUDIES. 



Collected at an elevation of 4000 feet above Waimea, Kauai. 

 It was growing on the banks of a stream in the woods, below 

 Gay & Robinson's Kaholumano house. 



October 4 (2852). 



TOUCHARDIA Gaud. Bot. Voy. Bon. t. 94; Wedd. 

 Monog. Urtic. 441. 1856. 



Touchardia latifolia Gaud. Bot. Voy. Bon. t. 94; Wedd. 

 Monog. Urtic. 442. pi. 13, f. C. 1856. 



As the plants figured in the Atlas of the Botany of the Voy- 

 age of the Bonite, are unaccompanied by either description or 

 reference to other published species they are all nomina nuda. 

 All of them however, seem to have been described by later au- 

 thors and credited to Gaudichaud. Weddell seems to have 

 been the first who characterized the genus Touchardia, with 

 its single species. Collected at Hanapepe falls, Kauai, at an 

 elevation of about 700 feet. The leaves are light green on both 

 faces, not "dark green,*' as Hillebrand says. They are rugose 

 on both faces, especially on the lower. The prominent veins 

 are red. In the dried specimens the leaves become much darker 

 than in the living state, thus perhaps accounting for Hille- 

 brand's error, but his expression " tripli-nerved, the lateral 

 nerves not reaching the middle of the margin,'' is not correct. 

 The fact is, that they are simply pinnately nerved, as is plainly 

 shown in Gaudichaud's plate. 



July 2 (2485); a Hawaiian genus, said by Hillebrand to occur 

 on all islands. 



URERA Gaud. Bot. Voy. Uranie. 496. 1830. 



Urera glabra (H. & A.) Wedd. Arch. Mus. Paris. 9:149. 1856. 

 Procris glabra H. & A. Bot. Beechy, 96. 1832. 



Hillebrand calls this variety gamma, of U. sandivicensis 

 Wedd. In addition to the differences brought out in the de- 

 scription of the two plants, and the very evident dissimilarity 

 to Gaudichaud's figure in Bot. Bon. t. 92, we have enough geo- 

 graphical range to separate them. U. sandivicensis is known 

 only from the island of Hawaii, while U. glabra has a northern 

 range, from Molokai to Kauai. Specimens were collected on 

 Kauai, at the head of the canon opposite Gay and Robinson's 

 Hanapepe valley house, at an elevation of about 1500 feet, and 

 also at about 3000 feet, at the foot of the tabular summit above 

 Waimea. 



July to October (1605); original locality, Oahu.
