copper plate of the U. S. Geological Survey is enclosed in cement, is Kapailoahiki. 

 Where the Heiau is situated is Kawakoo, then comes a pool called Waialeale, and 

 beyond it a hill overlooking Wailua, which is known as Waikini. 



THE SUMMIT BOG OP WEST MAUI, PUU KUKUI, ELEVATION 5788 FEET. 



Puu Kukui is a large, open, more or less flat plateau, composed of light-gray, 

 heavy, loamy soil. The vegetation is stunted, with the exception of such as 

 occurs in depressions or small gulches, and at the head of lao Valley, where 

 trees belonging to the middle forest region abound. 



The whole of Puu Kukui is a second Waialeale of Kauai, though a number 

 of plants are peculiar to the former. We find the same globose tussocks of Ore- 

 obulus furcatus and the very interesting Carex montis Eeka, besides Grami- 

 neae, such as Deschampsia australis forma longius aristaia, Calamagrostis Hille- 

 hrandii Hack. (nov. nom.), and others, while the juneaceous Ltizula hawaiiensis 

 var. glabrata grows in their company. One of the most striking vegetative fea- 

 tures is the great abundance of the very beautiful Lobelia Gaudichaudii. In 

 certain parts this plant covers the ground, and in the month of August it is in- 

 deed a beautiful sight. At about 5000 feet elevation these Lobelias are only 

 about 3 to 4 feet high, while at the extreme eastern end of this interesting bog 

 the plant is from 8 to 15 feet high and branches candelabra-like into usually 

 five erect racemes, bearing from 40 to 80 flowers each, while the plants in the 

 open bog have only one pyramidal raceme about 2 to 3 feet long. The flowers 

 are much larger than those of L. Kauaiensis, found on Waialeale, and also hand- 

 somer; thej' are cream-colored with a slight pinkish tinge, and are three inches 

 long and an inch wide. Lobelia macrostachys is here absent, while represented 

 on Waialeale, Kauai, by a new variety. The beautifully branching Lobelia 

 Gaudichaudii found on the brink of lao Valley is certainly distinct from the one 

 described by DeCandoUe in many particulars, especially in the very long lanceo- 

 late acuminate bracts, and shall from now on be known as var. longibracteata 

 Eock, var. nov. 



Next to the Lobelioideae found at the summit, the Compositae have three 

 representatives. Of greatest interest is the very handsome Wilkesia Grayana, 

 with its 5 to 8 feet tall stem, bearing a dense crown of verticillate leaves, out of 

 whose center the inflorescence comes forth as a large foliaceous raceme of one 

 and one-half to two feet in length, bearing yellow globose flower heads of about 

 10 lines in diameter. There is only one other species known of this interesting 

 genus, W. gymnoxiphium. It occurs in the dry districts of Kauai, especially on 

 open wind-swept cliffs in company with Lobelia yuccoides; while W. Grayana 

 grows in the open bog, which receives an enormous amount of rainfall. 



The second interesting genus is Argyroxiphium, which also belongs to the 

 most ancient of Hawaiian Compositae, though of American affinity. These two 

 genera are undoubtedly the oldest denizens of the Hawaiian Islands. The genus
