Clermontia tuberculata Forbes. 



(Plate 202.) 

 CLERMONTIA TUBERCULATA Forbes Occas. Papers B. P. Bish. Mus. V. (1912) 8, pi. 3. 



Leaves obovate to oblong, serrulate, glabrous, coriaceous, the veins on the under- 

 side minutely tuberculate 19.5 cm to 4 cm, with petioles 2 to 3 cm long; peduncle two- 

 flowered 5 mm long pedicels 3 cm, both covered with small tubercles; calyx tube cam- 

 panulate with short obtuse lobes, which together with the thick fleshy corolla is covered 

 with pronounced tubercles; anthers dark red, glabrous; berry globose, strongly tuberculate 

 on the outside 1.3 cm in diameter; seeds smooth, yellow, shiny, ovoid. 



This small tree, which reaches a height of about 12 to 15 feet, was discovered 

 by Mr. C. N. Forbes of the Bishop Museum, who collected it on the Island of 

 Maui on the slopes of Haleakala, in the wet forests near Ukulele (5000 feet). 



The writer collected specimens of this species a year later from the identical 

 tree from which Mr. Forbes derived his material. One other tree was seen 

 along a stream bed, its branches touching the rushing waters, between Puukakai 

 hill and the Kula pipe line trail, when in company with Dr. P. Ceresole. 



It comes nearest to Clermontia arborescens Hbd., but does not grow to such 

 a size. It is a very distinct species, differing from all other Clermontiae in its 

 tuberculate inflorescence, a character which, however, occurs in certain species 

 of Cyanea new to science.

CLERMONTIA COERULEA Hbd. Fl. Haw. Isl. (1888) 243; Del. Cast. 111. Fl. Ins Mar 

 Pacif. VII (1892) 211. 



Leaves oblong 12 to 15 cm long 2 to 4 cm wide on petioles of 3 to 5 cm shortly 

 acuminate, contracting at the base, minutely denticulate, glabrous above, membraneous, 

 with a scattered pubescence along the midrib underneath; peduncle slender 2.5 to 4 cm 

 long, with a pair of short bracts considerably above the middle, pedicels of the same 

 length or longer (in Hillebrand's specimen the pedicels are shorter) than the peduncle, 

 bracteolate below the middle; (Hillebrand's statement that" the bracteoles are at the 

 middle is incorrect; his specimen of C. coerulea which I examined has the bracteoles 

 also below the middle) calyx colored, the tube about 15 mm, turbinate, the lobes either 

 large 15 to 17 cm or minutely denticulate; corolla moderately curved about 4 cm long 

 greenish in Kau specimens, purplish in Kona specimens, of a thin texture; berry globose 

 yellow about 2 cm in diameter somewhat furrowed. 



What Clermontia macrocarpa is to Oahu, Clermontia coerulea is to Hawaii, 

 especially on the southern end. It is the most common Clermontia on the slopes 

 of Mauna Loa in Kau, from where it ranges way over to North Kona. It can be 

 found at an elevation of 2000 feet above Naalehu, Kau, in wet rain forests up to 

 an elevation of 4000 feet. It also occurs in the wet forest back of Kapua, where 

 it extends up into the Koa belt. It is not uncommon in the forests above Keala- 

 kekua and on the slopes of Hualalai back of Huehue. In Kau it is a tree 15 to 

 20 feet in height with a trunk of about -4 to 5 inches in diameter, and is freely 

 branching. In the specimens from Kau, the calyCine lobes are minutely denti- 

 culate, while in the Kona specimens the lobes are broad deltoid. In the latter 

 locality it is a shrub.
