Genus Isodendrion — St. John 
255 
localities of I. pyrifolium, L longtfolium, L 
laurifoltum^ and 1. Hillehrandii, but this new 
species is found in a different valley on the 
east, or windward, side of the Mt. Kaala 
massif. Its foliage suggests that of I. laurt- 
folium, but the characters of stipules, sepals, 
petals, and anthers are quite different. 
The specific name is made from the name 
of the Waianae Mountains, and the Latin 
place suffix, -ensis. 
Excluded Species 
Isodendron Fauriei Levi., Fedde Repert. 
Spec. Novarum Regni Veg. 11: 63, 1912. 
This binomial had the generic name mis- 
spelled; it should have read Isodendrion, the 
genus of Violaceae intended by Leveille. His 
labels on the two isotypes in the Bishop 
Museum also have ""Isodendron" in his hand- 
writing. His 3-line diagnosis, brief, as was 
his custom, gave few characters. This diagno- 
sis was worded so as to state the contrasting 
differences from ""L piri folio" [ = 1. pyri folium 
Gray]. It is certainly distinct from that, but 
so, too, is any alleged new species distinct if 
placed in the wrong family. Rock purchased 
a set of these Faurie collections from Leveille 
(the ones now in the Bishop Museum), then 
published a critical review of Leveille’s work. 
He reduced I. Fauriei Levi, to 1. pyri folium 
Gray. The two isotypes examined agree with 
the original description and positively are 
flowering specimens, from Molokai, of 
Gouania Hillehrandii Oliver in Hillebrand, 
Flora of the Hawaiian Islands 83, 1888, a 
member of the Rhamnaceae. This latter 
species was described from Maui, but now 
is known to occur also on Lanai and Molokai.
