Pittosporaeeae. 



Corrns Iiawaiiciisis or Alala, which pecks owen the hirge woody capsules and 

 feeds on the oily seeds within. The crow is peculiar to Kona, Hawaii. Nearly 

 SO';, of all the capsules of this species examined by the writer were eaten out 

 l)y these liirds, which are still very common.

A Biiiall trei? 15 to IS feet high with a roimil spreading ei'own, or wlien growing on 

 the high central plateau near Waialeale in the dense rain forest, a tree with very few 

 straight ascending branches; leaves crowded at the ends of the l)ranches or scattered, 

 oljovate olilong, shortly acuminate, with revolute margins, glabrous above, veins very 

 prouiiiieiit impressed, dark green with darlv brown or fulvous touientuni underneath,

 petioles of about 2 cm; inflorescence axillary and cauline, peduncle short, 12 mm, with 

 dark reildish brown tomentum, bracteate, bracts linear subulate, woolly as well as the 

 ovate '„o linear lanceolate sejjals; flowers on pedicels of 5 to lU mm, sepals 3 nun, tube 

 of the cream-colored corolla about 10 mm, the lobes 4 mm, stamens as long as the tube, 

 anthers oblong, style exserted, three times the length of the tomentose ovary; capsule

Tiiis very interesting tree is peculiar to the interioi', high plateau of Kauai, 

 especially the upper slopes of Waialeale. It grows in the swamps and swampy 

 foi'ests as well as along streambeds several miles inland from Kaholuamauo, at 

 an elevation of 4800 to 5000 feet. It is not uncommon in the more open flat 

 swamps in company with the thousands of Lobelia rnacrostachys at this region, 

 wliich is constantly wrapped in clouds. It is a rather curious plant, with a 

 short trunk and perfectly straight branches, which are only few, three or four, 

 and the large dark green and brown foliage. It is a constant species and grows 

 all over the summit of Kauai. It was collected b}' the writer first in Septem- 

 ber, 1009, and again in October, 1909, in the Alakai swamp near the head of 

 Wainiha, and on Waialeale October 20, 1911. The type is 8867 in the College 

 of Hawaii Herbarium, Honolulu, T. 11. The plant is named in honor of Mr. 

 Francis Gay of Kauai, whose kind hospitality and help in exploring the Kauai 

 forests the writer was fortunate to enjoy. At the very summit of Waialeale 

 in the open bog the writer found a variety of this species perfectly glabrous; it 

 was a shrub about 5 feet high, and may be described here as follows: 



Var. Waialealae var. nov. 



Leaves wdiorled at the ends of the branches, glabrous even the very young leaves, 

 obovate oblong, acuminate dull green on both sides, 5 to 10 cm long, 2 to 3.5 cm wide, 

 contracting into .'i petiole of 1 cm; capsules 2 cm each way, the valves deeply wrinkled 

 glabrous, young capsules ton)entose, seeds as in the species. 



Type No. 8866 in the College of Hawaii Herbarium, collected by the writer 

 October 10, 1911, at the summit bog of AA^aialeale, Kauai, elevation 5200 feet. It 

 grew in comi)any with Frlea Waialcalar. Labordca Waialealae, Lobelia Kauni- 

 evsis, etc.
