tain slope, with another species which has lately been described as Vaccinium 
Fauriei, a very distinct plant, with large, glaucous berries and small leaves; it 
grows much taller than V. reticulatum, and its berries are better tasting than 
those of the latter. 
Rubiaceae are also not uncommon. We find again Coprosma ernodeoides 
(Kukainene), Coprosma montana, and C. menziesii, with Sanicula sandwicensis, 
Plantago pachyphylla, Fragaria chilensis (the Chilean strawberry), and the iri- 
daceous Sisyrynchium acre, onee employed in tattooing by the Hawaiians. 
Ranunculus Hawaiiensis (Makou), the Hawaiian buttercup, is not uncommon 
on Puunianiau crater, and exceedingly plentiful on Mauna Kea, especially above 
Waiki and the craters Kaluamakani, Moano, ete. Silene struthioloides is found 
in black cinder in the erater, as well as on the slopes. Metrosideros polymorpha 
var. #. and °% are usually found in gulehes, together with Suttonia sp., Dodonaea 
eriocarpa, Sophora chrysophylla, and others. 
Special mention must be made of the wonderful development which the tem- 
perate genus Geranium has reached in these islands. Like the Violaceae, it has 
become arborescent and evolved into many species. The Hawaiian species of 
Geranium form a distinet section in the family, called Newrophyllodes. All 
species have a peculiar type of leaf which varies in size, shape, and pubescence. 
Geranium tridens is the common shrubby form which can be seen mixed with 
Sophora chrysophylla; its leaves are covered with a bright-silvery pubescence, 
and are tridentate at the apex, whence the name. It is the most common species 
on Haleakala, while G. arborewm is searcer. It is usually found in sheltered 
places near Puunianiau crater. The leaves are the largest of any of the Ha- 
waiian Geraniums, and are not silvery; the flowers are a purplish-red ; the petals 
are unequal, giving it the appearance of a violet. The name arboreum would 
have fitted better to G. multiflorum var. canum, which is, indeed, a small tree, 
15 feet in height, with a trunk of about 10 inches in diameter, while the former 
is a large shrub with drooping, rambling branches. G. multiflorum var. canum 
is not uncommon in the crater, but is found especially in Kaupo Gap, where it 
grows on upheaved aa lava, or fissures, together with Artemisia australis. 
Geranium ovatifolium, also a shrub, is found on the north bank of Haleakala 
crater. 
Labiatae are not very conspicuous in this region, though a few species of 
Phyllostegia and Stenogyne are not uncommon. One St. microphylla the writer 
found entangling Santalum Haleakalae; the leaves are very small, measuring 
only about three lines in length; the flowers are very inconspicuous and green. 
The epacridaceous shrub Styphelia tameiameia (Pukeawe) is the most common, 
while St. imbricata, very common on Mauna Kea, is only found near the summit 
of Haleakala. Tetramolopium humile and T. Chamissonis var. arbuscula, the 
Hawaiian daisies, occupy cracks between rocks and can also be found in black 
cinder. 
The most interesting discovery, icueey. made by the writer is a new species
