 A medium sized tree, leaves as in Suntalum rlUpticwm of Oahu, but glaucous under- 

 neath; panicles axillary, loose, few flowered; flowers on pedicels of 3 mm^ perigone dull 

 red, cylindrical 12 to 14 mm, the lobes as long as the tube or shorter; anthers as long as 

 the filaments; style nearly as long as the perigone, 3-cleft; drupe large 14 to 24 mm long, 

 the putamen rough, runcinate, crowned with membraneous annulus below the apex. 



This species is peculiar to the Island of Kauai and occurs in the forests of Hale- 

 manu at an elevation of 3000 to 4000 feet, where it is a tree 35 to 40 feet high, 

 occasionally. It can also be found in the woods of Kaholuamano, on the same 

 leeward side, above Waimea in the more dry regions in company with Elaeocarpus 

 bifidus (Kalia), Tetraplasandra Waimeae (Ohe kikoola), Pterotropia Eauaiensis 

 (Ohe ohe), Straussia (Kopiko), Bohea Mannii (Ahakea) and others. It also en- 

 croaches on the border of the rain forest where it is a straighter and taller tree 

 than when growing on the drier forehills. 



On the road to Halemanu, near Puu ka pele of the Waimea canyon, the writer 

 saw a fine specimen which was loaded with fruit, and the ground beneath was 

 covered with thousands of seeds, but none had sprouted. 



It may be remarked, that any attempt to germinate seeds of the Hawaiian 

 Sandalwoods resulted in failure. Hillebrand records a similar fate in his Flora 

 of the Hawaiian Islands.

A small tree with stiff erect branches; leaves thick, coriaceous to ehartaceous (at 



lower elevations) dull light green, ovate-obovate oblong 3 to 5 cm long, 25 to 30 mm 



broad, on petioles of 4 to 6 mm, bluntly acuminate or rounded; panicles crowded near the 



end of each branch, constituting a terminal corymb of 3 to 8 cm in length and also in 



width; flowers subsessile, of a deep scarlet red, the perigone 8 to 10 mm, with the lobes 



as long as the tube or longer; disc-lobes lanceolate, longer than the filaments; anthers 



on short filaments, their cells diverging at base and apex; style subexserted, 3-cleft; drupe 



ovoid 12 to 16 mm long, truncate at the base, and with a conical vertex at the apex and a 



short annulus below the same, putamen minutely runcinate. 



This species, which is easily distinguished from the other Hawaiian Sandal- 

 woods by its dense corymbose inflorescence, which is bright scarlet, is peculiar to 

 the Island of Maui, and at that confined to the eastern part Mt. Haleakala, after 

 which mountain it was named by Hillebrand, who records it as a shrub. 



It is, however, also a tree, though not of any size ; the highest trees observed by 

 the writer were about 25 feet. It grows around the crater of Puunianiau, on the 

 northeastern slope of Mt. Haleakala, at an elevation of 7000 to 9000 feet. It was
