OK LEAVER.

Sinuate^ from the Latin sinusj a bay ; this term is applied to leaves 
Fig. 44. 
which have their margins indent- 
ed with deep roundish divisions, 
as the leaf at b, Fig. 43. 
Emarginate, denotes a slight 
er indentation, as the leaf at c. 
Fig. 43. 
Flabelliform, or fan-shaped, 
(from Jlabellum., a fan ;) this 
form of the leaf is seen in 
some of the palms. In China 
they are used for fans, and sold 
to foreign merchants for th»» 
same purpose. Fig. 44 is a re 
presentation of the dwarf ;an 
palm. 
Stellated^ or whorled, (from stella, a start ;) 
this term is applied both to leaves and flowers, 
and relates to the manner in which they. grow 
around the stem, as in Fig. 45. 
Tubular: there are many varieties of this 
kind ; the leaf of the onion is a complete tube. 
The Sarracenia or side-saddle flower has the 
sides of its leaf united, forming a cup which is 
found filled with liquid, supposed to be a secre- 
tion from the vessels of the plant. In some 
countries of the torrid zone is the wild pine, 
(Tillandsia,) the leaves of which are hollowed 
out at their base, so as to be capable of containing more than a pint 
of fluid. A traveller says, "by making an incision into the base of 
this leaf, and collecting in our hats the water which it contained, we 
could obtain a sufficient supply for the uelief of the most intense 
thirst." This water is not a secretion from the plant, but is deposited 
during the rainy season. 
The pitcher- 
plant {Nepenthes 
distillatoria^ Fig 
46,) affords a most 
singular, tubular 
appendage, to its 
lanceolate leaf •, 
beyond the apex 
of the leaf a, the mid-rib extends in the form of a tendril ; at the ex- 
fremity of this tendril is the cylindrical cup or pitcher 6, about six 
inches in length and one and a half in diameter ; it is furnished with 
a hd, c, which opens and shuts with changes in the atmosphere. The 
cup is usually found filled with pure water, supposed to be a secre- 
tion from the plant. Insects which creep into it are drowned in the 
liquid, except a small species of shrimp, which Uves by feeding on the 
Sinuate — Emarginate— Flabelliform— Stellated— Tubular.
