the base; flowers 8 to 12 in a glomerule, connate with their bases; calyx 2 mm, free 
from the ovary, truncate, with 3-toothlets; corolla 8 mm, puberulous, tubular, 3-toothed; 
ile on the lowe ird of 
, ineluded; ovary small, globose 
anthers 3, 8 
depressed, immersed in an annular dise at the bottom of the calyx; style of the length of 
the calyx, bifid; drupe or berry of 4 distinct woody pyrena, fleshy, adherent with 
enclosed within the globose Si pyrena with 1 erect seed, and the calyxes paeaens 
into a synearpium which measures about 2.5 em in diameter. 
This exceedingly rare species was first collected by J. Lydgate in the forests 
of Hamakua and Waikapu, Maui. The writer’s attention was called to a tree 
erowing in the forest above Makawao, Maui, by Mr. L. v. Tempsky, who hav- 
ing become interested in native trees, happened to find it though practically 
hidden by Kopiko trees and Je-ie vines. It turned out to be this rare species. 
A large tree of this species was found by the writer along the ditch trail on 
the windward side of Mt. Haleakala, near Honomanu gorge. The tree is freely 
branching and has a trunk of over one foot in diameter. The wood is yellow. 
According to Hillebrand a variety occurs on Mt. Puakea of the Waianae range, 
Oahu. Its leaves are thicker and obtuse; the corolla is four-toothed and possesses 
4 stamens instead of three. First collected by Dr. H. Wawra. 
CAMPANULACEAE. 
Tribe Lobelioideae. 
While the family Campanulaceae numbers 59 genera, only the tribe Lobeli- 
oideae, with 22 genera, is of importance as far as Hawaii is concerned. Of this 
tribe, the Hawaiian Islands possesses six genera, five of which are endemic, the 
remaining one being the cosmopolitan genus Lobelia. Nowhere, with the ex- 
ception of South America, does this tribe reach such a wonderful development 
as in the Hawaiian Islands. It has the largest number of species of any plant 
family represented here in these islands; next to it ranks the Compositae. 
Many of our Lobelioideae are arborescent, some of them reaching a height of 
40 feet, and are a typical feature in the forests of Hawaii. The tribe in general 
is mainly tropical, and reaches to the southern temperate zone. Quite a number 
inhabit North America, and two the Mediterranean regions. The Hawaiian 
Islands, with its numerous arborescent forms, ranks next to South America, which 
has the largest number of species, as Centropogon Presl., with 80 to 90 species, 
and Siphocampylus Pohl, with 100 species, especially numerous in the Andes 
and Brazil. But if we compare South America in size with the Hawaiian Islands, 
which has up to 100 species of the tribe Lobelioideae, we find that really nowhere 
in the world does this tribe reach such a wonderful development in such a com- 
paratively small area. The other islands of the Pacifie are void of Lobelioideae, 
and only Tahiti and the Society Islands, with Raiatea, have in all four species 
belonging to three different genera. 
The Hawaiian species present sometimes really grotesque and specialized
