Rutaeeae. 



ginate, or subcordate leaves, with a 5 to 9 flowered panicle and capsules as in 



the species. This variety was collected by Hillebrand on the Island of ilaui in 



the Valley of Waihee and on the southern slopes of Mt. Haleakala ; the writer is 



not acquainted with this plant. 



Var. montana Rock var. nov. 



A slender tree 20 to 30 feet tall, the branches hirsute, leaves obovate to elliptieo- 

 oblong, bluntly acute at the apex, rounded at the base, very thick coriaceous, strongly 

 hirsute above when young but glabrate with age, densely pubescent underneath, the promi- 

 nent midrib hirsute as are the 1.5 to 4 cm long petioles, margins revolute, the secondary 

 veins parallel at nearly right angles to the midrib and united by an intramarginal nerve 

 not distant from the edge of the leaf, 6 to 12 cm long, 4 to 6 cm wide; inflorescence 

 axillary paniculate, densely hirsute 1 to 5 flowered; female flowers: sepals ovate- 

 triangular acute 3 mm, pubescent, as are the ovate-lanceolate petals, the latter twice as 

 long as the sepals, stamens rudimentary the height of the yellowish hirsuite ovary, anthers 

 sagittate, acute, filaments broad, glabrous; style hirsute, not quite as long as the petals, 

 with a bluntly four-lobed stigma; cajjsule largest in the genus, 5 cm in diameter, puberu- 

 lous, parted more than %, the cocci acute, at maturity the apex is deeply split, often one 

 or two abortive, always two seeded, the papery endocarp glabrous. 



This variety the writer discovered on the upper slopes of Mt. Hualalai at an 

 elevation of 5000 to 6000 feet on the rim of a crater called Puuki. It is a slender 

 tree 25 to 30 feet in height, but has a rather small trunk of 3 to 5 inches diameter. 

 It has long and slender branches which are foliate only at the ends. The writer 

 met with it also lower down at 3500 to 4000 feet, but it was more numerous 

 around the rims and at the floors of extinct craters, scattered over the western 

 slope of Hualalai in close vicinity to the dismal cinder plain above Huehue. 



The type is 3849 in the College of Hawaii Herbarium, flowering and fruiting 

 June, 1909. A very similar form with somewhat smaller capsules the writer 

 collected in the woods back of Waimea, Hawaii, fruiting June, 1910, no. 8426. 



Here must also be referred a shrubby form with long rambling branches, often 

 a small tree, which may be known as : 



Var. terminalis Rock var. nov. 



Leaves smaller, more or less glabrous, on short petioles of 1 to 1.5 cm, linear-oblong, 

 acute, thick coriaceous, 3.5 to 12 cm long, 2 to 6 cm wide, on long slender rambling 

 branches; capsules smaller than in variety mnntana, about 4 cm in diameter, usually 4 to 6 

 on a common bracteate peduncle of 1 cm or more, usually terminal, the ends of the branch- 

 lets drooping under the weight of the mature capsules, occasionally also axillary; capsula 

 as in var. montana, smaller. 



Collected at Auahi, southern slopes of Mt. Haleakala, Maui, on the lava fields 

 at an elevation of 2600 feet ; type no. 8655, fruiting November, 1910, College of 

 Hawaii Herbarium. 



On the Island of Lanai in the scrub vegetation of Mahana Valley occurs a 

 shrub with long rambling branches which becomes finally a vine entangling all 

 the neighboring trees and reaching way into their crowns. It is in all respects a 

 variety of Pelea volcanica and may be called : 



Var. lianoides Rock var. nov. 



Leaves as in the species, glabrate above, pubescent underneath, especially along the 

 salient midrib, on shorter petioles than in the species; inflorescence axillary, paniculate, 

 bearing from 3 to 10 flowers; female flowers large, pubescent, petals twice as long as the
