Eutaceae. 



the sagittate anthers on broad filaments; the glabrous ovary neither lobed nor notched, 

 entire, crowned by a short style with a bluntly notched stigma; capsule large. 3 cm in dia- 

 meter, chartaceous, entire, cuboid, scarcely even notched, glabrous, the ovary thin, trans- 

 parent, glabrous endocarp entirely loose; the cocci appear to be somewhat divided after 

 dehiscence of the capsule, each cocci 1 to 2 seeded; seeds large 8 mm. ovoid, black, shining. 



This very interesting species, which seems to be related to Hillebrand's var. ft 

 of Pelea sapotaefolia as far as capsules are concerned, occurs in the park-like 

 Kipuka Puaulu near the Volcano of Kilauea, on Hawaii, at an elevation of 4000 

 feet. It is a conspicuous tree on account of its peculiar branching habit, ex- 

 ceedingly large leaves, and very large cuboid capsules. It is quite plentiful in 

 company with Pelea rolcanica, Pelea dusiaefolia, Xanthoxylum, Sapindus sapo- 

 naria, Suttonia and other trees. It was discovered by the writer in July, 1911, 

 when he collected his type material, which is no. 10216 in the College of Haw r aii 

 Herbarium. Named in honor of Dr. A. Zahlbruckner, Director of the Botanical 

 Museum in Vienna.

Leaves opposite, oblong, rounded at the apex, subcordate at the base, dull green, 

 glabrous above, densely covered underneath with an olivaceous tomentum, as well as the 

 2.5 to 4 cm long petiole, 10 to 20 cm long, o to 9 cm wide, thick coriaceous, quite opaque, 

 marginal nerve wanting; young leaves golden yellow, densely hirsute; inflorescence 10 to 

 15 cm and more long, cyniosely paniculate, densely tomentose, on a common peduncle of 

 4 to 6 cm, bracteate throughout, the bracts 1 to 1.5 cm, linear oblong, acuminate, ultimate 

 pedicels 3 to 5 mm long; flowers 10 to 200 on a single inflorescence; floral bracts subulate, 

 enclosing the persistent calyx which in turn encloses the four valvate petals of 5 mm 

 in the fertile flowers; male flowers larger than the female flowers, calyx half the length 

 of the corolla; stamens 8, four shorter than the petals, the remaining four as long as the 

 corolla, and sometimes protruding, ovary rudimentary with 4 minute stigmatic branches; 

 female flowers, calyx as long as the corolla, silky gray, the lobes acuminate, smaller than 

 the male flowers; ovary large glabrous, four lobed, style 4 mm long with a white four 

 lobed stigma, each lobe 2 mm long; follicles glabrous, 3 cm each way, carpels parted their 

 entire length; endocarp yellow, shining, glabrous, more or less loose; each follicle 1 to 2 

 seeded, seeds ovoid, black, shining. 



This exceedingly interesting species was discovered by the writer on the lava 

 fields of Mt. Haleakala on the southern slopes, in the district of Kahikinui, on 

 Maui. The particular locality where this tree occurs is called Auahi, and is sit- 

 uated at an elevation of 2600 to 3000 feet. It is the richest botanical section in 

 the whole Territory, with the exception of Puuwaawaa on Hawaii. 



The species in question is a good-sized tree 30 to 40 feet in height, with a 

 trunk of over one foot in diameter, which is clothed in a gray smooth bark. The 

 tree is badly attacked by a lichen, a species of Usnea, probably australis, which 

 seems to check the growth of the trees; they are literally covered, trunk and 

 branches, with this ungainly looking lichen. 



The tree was discovered during November, 1910, when the- first specimens were 

 collected (no. 8646 flowering and fruiting). During the first part of March, 

 1912, the writer revisited that locality for the purpose of collecting additional 

 material and also to secure photographs. Many trees were then in flower, and
