Fagerldnd* and Mitchell discuss the habitat of this species, 
which is on ash deposits in transitions between forest and desert 
'around the Kilauea area (on the Ka’u desert above the Puna coast). 
Hillebrand (and Forbes, repeating Hillebrand’s statement) records 
the species from the small barren island of Kahoolawe, on the basis 
of a specimen collected by Lydgate. I have not seen this specimen.

Sect. Catodasis Leg RAND, subsectx ? (incertae sedis). 
5. PoTtulaca hawaiiensis DEGENER in FI. Haw. fam. 117. 1937; 
Fagerlund and Mitchell l.c. 1944; Stone l.c. 1959. 
Diffuse perennial 1-2 cm. long with thick purplish-gray branches,

5-15 X 3-4 mm., about 2 mm. thick, obtuse at apex and base, shallowly 
sulcate above, the petiole 1 mm. long; axils with tawny persistent 
hairs 1-3 mm. long (paler than those of P. sclerocarpa)^ calyx 4 mm. 
long, sepals obtuse, scarious; petals 5, obcordate, about 10x8 mm,, 
basally white, apically pink; stamens about 30; ovary turbinate, 
stigmas 7, branches about 2 mm. long; capsule lid ovoid, about 0.05 
mm. thick; placenta filiform, flaccid, branched; seeds shining dark 
mahogany, minutely stellulate-rugulose. 
Distribution ; Hawaii (South Point; Waiohinu; Ka’u Desert). 
0 > The type is DEGENER 10914. The most recent collection is 
STONE 2870 from Kamoamoa, Puna, Hawaii. 
Legrand does not account for this species in his treatment of the 
genus, and it does not seem to fit well into the established sections 
except for sect. Catoclasis. It does not appear to belong to the 
subsections of that section. For the present it appears to be incertae 
sedis. It may be the type of a new subsection. ,
