Campanulaceae. 



Clermontia Haleakalensis Rock, sp. nov. 



(Plates 204, 205.) 



Leaves 20 to 30 em long including the short -margined petiole, fleshy, 1.5 to 4 (.to 

 wide, obtuse, oblong lanceolate, dark green above, pale underneath, midrib thick promi- 

 nent, veins impressed, pellucid, the upper half crenate, lower half entire, glabrous, gradu- 

 ally tapering into a short margined petiole; cymes in the axils of the leaves, peduncle 2 to 

 5 cm long, bearing usually 6 flowers on pedicels of 1 to 1.5 em, the bracts linear subulate 

 about 7 mm, the pedicels bibracteolate below the middle; calyx tube oblong turbinate 

 1.5 cm slightly pubescent, the lobes linear subulate 5 mm long, corolla whitish green 3.5 

 to .4 cm long, curved, the dorsal slit not always extending to the base, sometimes only 

 to the middle, lobes linear lanceolate glabrous; staminal column white pubescent at the 

 base, as is the disc, glabrous in the upper part, the two lower anthers penicillate; style 

 slightly pubescent, inner side of the staminal column hispid with white hair in the 

 "lower half, berry oblong, seeds smooth whitish. 



A small tree 10 to 20 feet tall, with few very robust branches, having at first 

 glance the aspect of a Dracaena. It is soft-wooded, and glabrous. This very 

 curious tree, which has almost an antediluvian appearance, comes nearly between 

 Clermontia and Cyanea. Its decidedly cymose inflorescence places it with the 

 former genus, while the dorsal slit of the corolla does not always extend to the 

 base, but the middle. It also has a characteristic of the genus Delissea, and that 

 is the thickened portion or knob in the flower bud about the middle, indicating 

 the termination of the dorsal slit ; though the seeds, which in Delissea are deeply 

 wrinkled, are smooth and shining in the species in question. 



This remarkable tree is undoubtedly one of the oldest forms of our Hawaiian 

 Lobelioideae, as it is so strikingly different from all the rest of the Lobelioideae 

 inhabiting these islands. 



This particular species was discovered by the writer October 11, 1910, on the 

 Island of Maui, on the western slopes of Mt. Haleakala, on the crater of Puu- 

 nianiau, at an elevation of 7000 feet, in a locality where no one would expect to 

 find a member of this wonderful tribe. It grows in open, dry scrub in company 

 with plants belonging to the upper forest zone, such as Baillardia platyphylla, 

 Argyroxiphium virescens, Sophora chrysopliylla, Santalum Haleakalae, etc. Un- 

 fortunately, only three trees are in existence, and as they are peculiar to the 

 above locality, it will not be long before they will have shared the fate of so 

 many of our native trees, becoming extinct, as cattle have free access and browse 

 on the lower branches within their reach. The writer appealed to the manager 

 of Haleakala ranch to protect these trees from the ravages of cattle, which he 

 kindly promised to do. 



The type specimen is No. 8595 in the Herbarium of the College of Hawaii. 



CYANEA Gaud. 

 (Kittelia Reichb., Marcrochilus Presl.) 



Calycine lobes of variable length, from dentate to foliaceous; the dorsal slit of the 

 corolla extending to the middle. The two lower small anthers or all penicillate; seeds 

 crustaceous shining smooth. Shrubs or small trees with erect simple stem or branches, 

 occasionally covered with thorns. Leaves entire, lobed, or pinnate. Flowers bluish or 

 purple or white in axillary racemes.
