810 USEFUL PLANTS OF GUAM. 
Lobelia koenigii. FANFLOWER. 
Family Goodeniaceae. 
LocaL NAMEs.—Nanaso (Guam); Nano (Solomon Islands); Bokiibok, Balék- 
bal6k, Bosb6ron, Panabdlong (Philippines); To’ito’idve’a (Samoa); Naupaka 
(Hawaii); Taccadia (India, Ceylon). ; 
A shrub growing on the strand, widely spread throughout the tropical islands of 
the Pacific and Indian oceans and on the shores of tropical Asia and Australia. 
Stem branching extensively from the base, thick and succulent and full of pith 
when young, but later becoming hard and woody. Leaves and inflorescence gen- 
erally silky-pubescent, rarely glabrescent; leaves fleshy, obovate, tufted in the axils, 
with long silky hairs, alternate, entire or rarely obscurely crenate, rounded at the 
top or even emarginate, narrowed at the base into a short petiole, the nerves hidden; 
cymes axillary, shorter than the leaf; bracts small; corolla white, often with purple 
streaks, slit to the base on the upper side, its lobes margined, spreading somewhat 
like a miniature fan; calyx tomentose, 5-fid, the lobes linear-lanceolate, enlarging 
in fruit; stamens 5, inserted at the base of the corolla, alternate with its lobes; 
anthers free; style simple, with a cup-shaped ciliate indusium including the stigma; 
fruit a round, succulent drupe, with a bony endocarp. 
Common near the shore, and like several other shore plants reappearing on the 
treeless sabanas of the island. In India the young leaves are eaten as a pot herb, 
The soft, snow-white pith, an inch in diameter or more, is sometimes cut into thin 
paper-like flakes by the Siamese, Malayans, and Chinese and made into artificial 
flowers, butterflies, and other objects. The wood is coarse, fibrous, and useless.

Lobelia koenigii (Vahl). 
Scaevola koenigit Vahl, Svm. Bot. 3: 36. 1794. 
Lobelia sericea koenigii Kuntze, Rey. Gen, 2: 377. 1891. 
The genus Lobelia as established by Linneus in the Species Plantarum 2:929. 175! 
and Genera Plantarum ed. 5. 401.1754, contained 25 species, only one of which 
belonged to the Lobelia of Plumier from whom Linneus adopted the name. This 
species, Lobelia plumierii, was the first to be referred toa new genus, Scaevola, under 
the name Scaevola lobelia, proposed by Linneus in 1771, and thus became its type 
species. This treatment has been followed by most modern authors, but in the 
application of the names in accordance with the principle of generic types the course 
of several well-known authors who wrote soon after the appearance of the species 
Plantarum seems to indicate a more careful regard for the correct application of 
generic names. Notable among these was Miller, who, in the seventh edition of the 
Gardener’s Dictionary, wisely restricted the name Lobelia to the original of Plumier 
and the type species of the genus as established by Linneus, and adopted the 
Tournefortian name Rapuntium for the species which modern authors (Otto Kuntze, 
I think, alone excepted) have allowed to remain under the name Lobelia. 
Lochnera rosea. OLD MAID. 
Family Apocynaceae, 
LocaL yameEs,—Vicaria, Dominica (Cuba); Madagascar periwinkle. 
A plant growing in cultivation and in waste places with pretty salver-shaped rose- 
colored flowers (sometimes white with acrimsoneye). Leaves spi on-shaped, oblong; 
flowers subsessile in pairs from the same node of the stem; calyx 5-parted, seg- 
ments lanceolate, acuminate, much shorter than the slender corolla tube; corolla 
callous at the pubescent, narrow throat; stamens inserted upon the upper part of the 
tube; ovaries 2, slightly cohering, alternating with 2 oblong disk glands, which 
exceed the ovaries. This genus differs from Vinca in having the filaments thin and 
the anthers and stigma not hairy.
