138 Rock: NEW HAWAIIAN PLANTS 
rosette with the leaves densely packed at the apex in an almost 
horizontal position, that is, at right angles to the stem. It grows 
in company with Trematolobelia macrostachys (Hook. & Arn.), 
Zahlbr., Dubautia laxa Hook. & Arn., Metrosideros rugosa Gray, and 
other species. Notwithstanding that the flowers of this new 
species are unknown, the plant is so distinct from all of our other 
lobelias that it can well be described at present. 
The plant is evidently related to Lobelia hypoleuca Hillbrd., 
from which it differs in the solid stem, thick, coriaceous, closely 
reticulate leaves, not silvery underneath but hirsute, being covered 
with fawn-colored or dirty gray hair. In Lobelia hypoleuca, which 
is a branching species, the leaves are few and more or less scattered, 
thin and chartaceous; it does not ascend to such high elevations, 
but remains more at the lower levels, from 1,000 to 1,500 feet, in 
very sheltered situations, especially deep ravines. 
5. Straussia glomerata sp. nov. 
A medium-sized tree, 10 m. or more in height, trunk straight, 
crown round and of rather small dimension; stipules cup-shaped, 
not triangular, sheathing and of even height, 3 mm. high, soon 
deciduous; leaves obovate, coriaceous, glossy and smooth above, 
dull and pubescent beneath, especially along the midrib and veins, 
pubescent glands present in the axils of veins and midrib, 5-10 
cm. long, 4.5-6.5 cm. wide, on petioles 15 mm. long, rounded at 
the apex, cuneate at the base; panicle erect, not drooping save 
when in full fruit, 2-4 cm. long, distinctly angular, hirsute with 
dirty yellowish hair, whorls two or three, of very short rays 2-6 
mm. long; flowers sessile; calyx minute, 0.5-0.75 mm. long, densely 
hirsute, truncate; corolla greenish white, minute, tube 0.5 mm. 
long, lobes 1.5 mm. long, glabrous, stamens minute, filaments 0.2 5 
mm. long; the convex disk densely hirsute; fruits numerous, densely 
agglomerate, forming a densely packed globose head, hiding all 
whorls and rays, fruits yellow, pubescent to hirsute, obovate, 9 
mm. long, 6-6.5 mm. wide, crowned by a rounded, dome-shaped, 
projecting disk.
