different from its appearance in the'wild state, in 
' characteristically produces small reddish branches. The difference 
in habitat is no doubt the basis for the differences in appearance. 
The often excessively dry areas which the plants inhabit in nature, 
with an infertile, thin and porous soil, is in contrast to the rich soil 
of Mt. Tantalus and Round Top. Good drainage is required, how¬ 
ever, and the plants will not long tolerate standing water or saturat¬ 
ed clay soil. A top layer of relatively unmixed porous lava gravel 
appears to be a satisfactory medium for growth, In this pampered 
states this handsome species will flower profusely on nearly every 
sunny morning, and until about noon will present the appearance of 
a pink-dotted green carpet. 
St. John describes in detail the aspect of specimens cultivated at 
the Pineapple ^Research Institute (on the University of Hawaii 
grounds), and compares the habit of -plants grown in full sun and 
those grown in shade, the former more prostrate and reddish, the 
latter more erect and green, and producing fewer flowers. 
A small clump of this species has been planted in the courtyard 
of the Bishop Museum near the north court gate. , Herbarium 
specimens from the Wahaula plants, and from new growth from the 
cuttings are preserved at the Bishop Museum and at the Park Natu¬ 
ralist Headquarters, Hawaii Section, Hawaii National Park.
