The windward side is precipitous, especially in the Xapali region. This region 

 is intersected by deep valleys as ^^'ainiha, Kalihiwai, and in the Xapali region 

 by Hanakapiai, Kalalau and other valleys. So far Kauai has produced four 

 species of Prifcliardia hut undoubtedly still others occur in some of the inacces- 

 sible mountain fastnesses on the precipitous leeward side. Two species occur 

 on the lee side of the island. Prifcliardia criopliora Becc. is found on the ridge 

 west of Halemanu, known as Kaunuohua, at an elcAation of 4200 feet near the 

 clififs overlooking Kalalau. (See PI. X\'III, A.) It is a rather tall species 

 45 feet or more in heioht and grows in boggy soil associated with species of 

 Pclca, as Pclca aiiisafa. Pclca uiicrocarpa. Tctraplasaiidra W'aiiiicac, Coreopsis 

 cosmoidcs, CJicirodcndron platypliylliiiii, Lysiiiiachia gliitiiiosa and others. It 

 is closely related to Prifcliardia minor Becc. which occurs also on the leeward 

 side. This is a smaller palm in stature hut larger in crown; it occurs near 

 Kaholuamano at an elevation of 3600 feet on steep slopes overlooking Mahana 

 valley in a drier situation than Prifcliardia criopliora. 



In February, 1920, I again visited Kauai for the purpose of photographing 

 palms During this visit information furnished by natives and others whose 

 business takes them into remote mountainous region, resulted in the discovery 

 of two very distinct and new species. One was found near the so-called Pole 

 Line Trail on Summit Camp at an elevation of 1900 feet. It is described in 

 this paper as Prifcliardia Hardyi Rock and is one of the tallest species, measuring 

 about 70 feet in height. A few indi\-iduals were found. The one here pictured 

 (see PI. XIII, A) grew in a deep ravine; and so only a fourth of the actual 

 trunk is visible in the photograph. This species is related to Prifcliardia minor 

 and with Prifcliardia criopliora had a common origin. The fourth species, 

 Prifcliardia z'iscosa Rock, was discovered not very far from the Pole Line Trail 

 but on the clififs in a branch of Kalihiwai A'alley at an elevation of about 2000 

 feet. This species is decidedly distinct and has verv little in common with the 

 other three species found on Kauai. It is vmique among the Hawaiian species 

 in its very viscous inflorescence. The trunk is not nearly as tall as in Prifcliardia 

 criopliora or Pr. Hardyi, measuring only about 20 feet in height. With the 

 exception of Prifcliardia I'iscosa. the other Kauai sjiecies are small fruited with 

 elliptical, not spherical, fruits, while Prifcliardia I'iscosa has obovate to pyriform 

 large fruits They are all shiny black when mature. 



OAHU. 



The island of Oahu which is separated from Kauai by a channel 60 miles 

 wide, is divided into two main mountain ranges. The western one nearest to Kauai, 

 is known as the W'aianae range which culminates in Mt. Kaala. the highest 

 point of Oahu, 4030 feet in height. The other range forms the main back bone 

 of the island and is known as the Koolau range with mountains a little over 

 3000 feet in height. So far, only three species of Prifcliardia have been found 

 on Oahu. One, Prifcliardia kaalae (see PL VI, A), is restricted to the W'aianae
