Halawa, and its even, although steep, slope on the lee side, is the region in which 

 Pritchardias abound. The most common species found on Molokai is Prifciiardia 

 Gaitdiclioudii (Mart.) Seem, et ^^'endl. Tt occurs not only in practically all the 

 valleys on the windward side but also on the rock islets off the coast of Molokai. 

 It seems to be a variable species which lo\'es the windswept, weather-beaten 

 cliffs, as the accompanying illustration testifies (see PI. VIII, A). It clings to 

 sheer walls where hardly any other vegetation can take hold. I observed it 

 growing in a straight line, one tree above another, along the precipitous walls 

 of a \yaterfall without the sign of any other tree or even shrub. On the steep 

 wall? or cliffs which rise vertically from a deep sea this species abounds, with 

 Pandauus tccforius as well as on Haupu and Huela, two spurs jutting out into 

 the sea from the main cliffs. One of the islets oft' the coast harbors several 

 specimens of this species. 



On the ridge dividing Waihanau Valley from Waialeia A'alley, PrifcJiardia 

 Gaudichaudii is c|uite common, but only on the slopes towards the sea, while a 

 little further inland on the flats occurs another and very distinct species, Prifcii- 

 ardia [.07^'rcya)ia Rock. It is a much larger ]«lm but of short stature and has 

 the largest fruits of any species in the genus. These two species had undoubtedly 

 a common origin. A new variety recently discovered by me in the same locality 

 grow in company with Prifciiardia Gaudichaudii nearer the edge of the cliff's 

 immediately above the sea but at a height of about 3,000 feet. This variety 

 must be referred to Prifciiardia Loivrcyaiia Rock; it diff'ers from the species in 

 the smaller fruits, which are pointed at both ends, in the smaller stature of the 

 palm, and in the shorter spadices. 



The lee side of IMolokai, back of Kamolo, is intersected by several ravines 

 which are more or less shallow ; the actual slopes are, however, practically 

 barren and covered with loose volcanic rocks up to nearly 2,000 feet elevation. 

 In that region Dodoiiaca criocarpa is \-ery common and some xerophytic trees as 

 Dracaena aiirca. Xantlioxyhuii iiiaiiiciisc, Osuiaiiflius saiidzvicciisis, Sidcroxylon 

 sandwiccnsc var. iiiolokaiciisc. At the two thousand-foot level Dodoiiaca sfcnop- 

 tera is very common and especially at Puakoolau and Kamolo proper. The region 

 must be considered a subxerophytic one although a thousantl feet higher the rain 

 forest commences. It was in this subxerophytic region that another new Prifcii- 

 ardia was discovered. It is herein described as Pr. Miniroi Rock, in honor of Mr. 

 James Munro to whom I am greatly indebted for many courtesies and hospitality. 

 (See PI. XIV, zJ.) 



The species is exceedingly interesting, as it is one of the few occurring 

 in semi-arid regions. It is a small palm, with very short woolly panicles and 

 perfectly spherical small brown fruits. The costae on the under side of the leaf 

 are covered with large and robust broAvnish-green scales such as have not been 

 observed in any other species. 



Prifciiardia brcz'icaly.v, also a newly discovered species, occurs in W'ailau
