Urtieaceae. 
On the island of Kauai, on the leeward side in the forest of Kaholuamano, 
grows a small tree about 18 feet high, which differs very materially from Urera 
sandvicensis, found on Hawaii. It is here described as a new variety under the 
name Urera sandvicensis var. Kauaiensis. The native name of this tree is Hona. 
Var. Kauaiensis var. nov. 
Hona. 
Leaves Ladera ovate, bluntly accuminate at the apex, truncate to cuneate at the 
base, evenly crenate to serrate, thick coriaceous, dark ee: with bright red midrib

The tree, eae is called Hona by the natives, was the only one observed in the 
forests of Kaholuamano, Kauai, along a streambed. It was collected by the 
writer in August, 1909, and October, 1911. The number of the type is 9006 in 
the College of Hawaii Herbarium. It differs from the species in its very long 
petioled coriaceous leaves, shortly peduncled male inflorescence, which is of a 
bright red color, purple anthers and large perigones. 
Mention may be made here of Urera Kaalae Wawra, a small tree found in the 
Waianae range of Oahu. It differs from U. Sandvicensis in the palmately 
nerved, cordate leaves, small triangular stipules and bracteolate inflorescence. 
The plant was discovered by Wawra and described in Flora (1874), p. 542. His 
specimens came from Mt. Puakea of the Kaala range. Not collected by the 
writer

gray pubescence underneath, entire to serrate leaves; stipeles bifid, easily caducous. 
Flower clusters oinbone: single in the leaf axils, or in some plants, not from the Ha 
waiian Islands, arranged in catkins. 
The genus Pipturus consists of about 12 species, which are distributed over 
the Oceanic Islands, Hawaiian Islands, and Mascarene Islands to Australia. The 
Hawaiian species are all called Mamaki or Mamake; they furnished, next to 
auke (Brousonetia papyrifera), the fiber for their tapa or paper eloth.
