Heller : plants of the Hawaiian islands. 865 



fully developed cymes large, with densely wooly peduncles an 

 inch in length; calyx very wooly, except the short, triangular 

 lobes, which are almost glabrous, but glandular; petals red, 

 broadly obovate, about a quarter of an inch in length, glandular 

 on the outside, ciliate; stamens numerous, an inch long, dark 

 red; style almost as long, and of the same color as the stamens, 

 not enlarged at the stigmatose apex; ovary deeply immersed 

 in the bottom of the calyx, its disk-like top very glandular and 

 resinous. 



The type is No. 2738, collected in the bog at the head of the 

 Wahiawa river. Kauai, at an elevation of 3000 feet. So far as 

 size is concerned, this is near Hillebrand's var. gamma,bvLt he says 

 •' a low trailing shrub, with stems only 3-6 feet long." This is 

 strictly erect, has larger leaves, and more numerous flowers 

 than his plant. The corolla, stamens, and style are deep red, 

 and the growing ends of the branches are usually tomentose, 

 with traces of pubescence occasionally on the midribs of young 

 leaves. It is probably confined to this bog and the large one 

 on the plateau above Waimea. 



Nani(a) macropus (H. & A.) Kuntze, Rev. Gen. PI. 242. 1891. 

 Metrosideros macropus H. & A. Bot. Beechy, 83. 1832. 

 Typical trees of this species are not uncommon on the slopes 

 of Waiolani, back of Honolulu, but specimens were not collect- 

 ed from them. Hillebrand has the species from Kauai with 

 "leaves contracting at the base." Of my specimens, No. 2762, 

 which was labeled Metrosideros macropus, has leaves decidedly 

 contracted at the base, and is not good macropus, either accord- 

 ing to specimens or the type description. It was collected on 

 the ridge between the Hanapepe and Wahiawa rivers. The 

 specimens are from a small, well proportioned tree. The 

 leaves are elliptical-lanceolate, glabrous, thick and shining, the 

 largest an inch and a half wide by slightly over two inches in 

 length, on bright yellow petioles of almost an inch in length. 

 Metrosideros macropus is described as glabrous throughout, yet 

 the peduncles and calyx in these specimens are tomentose. 

 Perhaps the proper course would be to describe it as a new 

 species, for leaving out the pubescence on pedicels and calyx, 

 it is nearer to N. tremuloides than to N. macropus, where Hille- 

 brand placed it.
