Notes on Hawaiian Lobelioideae, with descriptions of new species and 
varieties 
JosePH F. Rock 
(WITH PLATES 9-16) 
The writer has prepared a monograph on the Hawaiian lobelioi- 
deous genera Cyanea, Rollandia, Clermontia, Delissea, Tremato- 
lobelia and Brighamia, and on the endemic species of the genus Lo- 
belia. But owing to the length of time necessary for the publica- 
tion of the rather voluminous manuscript of the whole monograph, 
he thought it wise to publish the new species first in botanical peri- 
odicals or bulletins. The majority of the new species of Cyanea 
and Clermontia have appeared in the writer’s book on the In- 
digenous Trees of the Hawaiian Islands (1913), in Botanical Bul- 
letin No. 2, of the College of Hawaii Publications and in the Bul- 
letin of the Torrey Botanical Club. With two exceptions the 
species and varieties described in the present paper belong to the 
genus Cyanea, which has by far the largest number of species of 
the lobelioideous genera represented in the Islands. Clermontia 
comes next, with Rollandia and Delissea following. 
1. Cyanea noli-me-tangere sp. nov. 
Plant subherbaceous, 3-20 dm. high, terrestrial, branching only 
when broken, spinescent throughout, with the exception of 
the fruit and corolla; stem green, somewhat fleshy, entirely 
covered with strong, pale yellow, hollow spines; leaves bright 
green, ovate-oblong, somewhat acute at the apex, rounded at the 
base, thin in texture, irregularly and sinuately notched, with 
minute, mucronulate teeth along the margin, covered with yellow 
spines at more or less regular intervals of 7-10 mm. on both
