Dracaena aurea Mann, Proc. Amer. Acad. 7: 207. 1867. 



Hillebrand says this species is " not uncommon on all islands 

 at altitudes of 1000 to 2500 feet, as in Nuuanu, Oahu, near the 

 Pali." If it ever was common on Oahu, it has become rather 

 scarce during the intervening years. My first specimens were 

 collected at the Nuuanu Pali, where there are several trees, 

 but it is not at all common. On Kauai, it is plentiful between 

 the Hanapepe and Waimea rivers. Above Waimea, on the edge 

 of the tabular summit, at about 3500 feet elevation it is very 

 abundant. One stunted tree was observed in the forest on Ka- 

 holuamanoa at 4000 feet. Mann's statement that the berry is 

 red, is much more correct than Hillebrand's designation of it as 

 ' ' yellow. " Red-brown is perhaps the proper term. The grace- 

 ful, palm-like habit of this tree, is quite a contrast to the her- 

 baceous Liliaceous plants of more temperate climes. 



May 21 (2362); the type number is M. & B. 362, without ex- 

 act locality, but probably from Oahu.

According to Hillebrand this species ranges from Kauai to 

 Maui. Specimens with fully formed but unripe fruit, were 

 collected on the lower slopes of Konahuanui, back of Pauoa, 

 island of Oahu, at an elevation of about 2000 feet. The plant 

 usually forms a dense tangle, climbing over bushes and trees.

Dioscorea sativa L. Sp. PL Ed. 2, 1463. 1763. 



This species with its peculiar, potato- like rhizome, is com- 

 mon on the heights of Pauoa, Oahu. On Kauai, it is rather 

 common in Hanapepe valley. Although hundreds of plants 

 were seen, only a few were found in flower, but all, except 

 those in flower, bore bulbs which form in the axils of the 

 leaves. These bulbs are often an inch and a half in diameter. 



August 14 (2728), original locality, "in Indiis."
