CATCHFLY, _Silene struthioloides_ A. Gray. Fig. 16. A plant that is typical only of arid Cinders and ash on East Maui and on the island of Hawaii. With the silversword as its companion in Haleakala Crater the plants are found at the bases of barren cones. They show neat adaptation to their stark home. The Haleakala plants, as illustrated, are low and compact, but those growing at Kilauea Crater bear only a few awl-shaped leaves and resemble dead twigs. The thick tap roots are sweet and edible. About 250 species belong to this genus, a member of the Pink or Carnation Family. A well-known introduced weed, the English catchfly, _Silene anglica_ L., was reported by Degener at 10,000 feet on Haleakala.
’OHA, _Labelia grayana_ E. Wimm. A low plant with woody trailing stems with knobby leaf scars and ending with a crowded arrangement of silvery, linear leaves, 4-8 inches long and crowned with densely flowered racemes, 6-15 inches long. The flowers are lilac-blue with a satiny sheen. The plant is not uncommon on wet _pali_ from 5,000-7,000 feet at Paliku, Kaupo and Koolau Gaps, and in the northwestern end of the crater. It is a glorious plant worth hunting for and going miles to see.
NAUPAKA. _Scaevola chamissoniana_ Gaud. This shrub was noted only on the east side of Kaupo Gap. This is a varying species found up to the 6,000-foot elevation. It is not common and blooms in summer. The white flowers with purplish streaks are slit to the base on the upper side. They look like flower-halves rather than complete corollas. There are several legends about the peculiar flower, each dealing with lovers separated from each other. In a song composed about it, the lovers were forceably parted, so the girl divided a perfect corolla, giving one half to her lover while keeping the other half herself. One of the lovers carried the flower to the sea, _naupaka kahakai_, the other to the mountain, _naupaka kuahiwi_, where the plants are found today.
MAUI WORMWOOD, _Artemisia mauiensis_ (A. Gray) Skottsb. Fig. 17. Typical of Maui and found only on Haleakala, this hoary ornamental shrub, usually 2-3 feet high, perches on cliffs usually above the reach of man. It has a densely-branched crown with silvery leaves that are aromatic and bitter. The leaves are composed of thin segments that are covered with a mat of cottony hair, giving the plant a silvery appearance. The small orange flowers are borne in terminal panicles.
