bling each other in form and color, as in the Tulip and Lily, the flower 

 ■is called Liliaceous. 



A Galeate corolla is one in which the upper petal is arched in the 

 shape of a helmet, called the Galea, as in Aconite. 



The LiGULATE or Strap-shaped corolla is nearly confined to the 

 family Compositae. It is usually tubular at the base, the remainder 

 resembling a single petal. Ex. : Marigold, and Arnica Flowers. 



Labiate, or BI-labiate, having two lips, the upper composed of two 

 petals, the lower one of three. This form of corolla gives name to the 

 Labiate, while in the family Leguminos^ this arrangement is 

 sometimes reversed. The corolla may be either ringent, or gaping, 

 as in Sage, or personate, when the throat is nearly closed by a 

 projection of the lower lip, as in Snapdragon. 



Rotate, Wheel-shaped, when the tube is short and the division of 

 the limb radiate from it like the spokes of a wheel. Ex.: The Potato 

 blossom. 



Crateriform, Saucer-shaped, like the last, except that the margin 

 is turned upward or cupped. Ex.: Kalmia latifolia (Mt. Laurel). 



Hypoceateriform, or Salver-shaped (more correctly, hypocrateri- 

 morphous), when the tube is long and slender, as in Phlox or Trailing 

 Arbutus and abruptly expands into a flat limb. The name is derived 

 from that of the ancient Salver, or hypocraterium with the stem or 

 handle beneath. 



When of nearly cylindrical form the corolla is Tubular, as in the 

 Honeysuckle, and Stramonium. 



Funnel-form (Infundibuliform), such as the corolla of the common 

 Morning Glory, a tube gradually enlarging from the base upward into 

 an expanded border or limb. 



Campanulate, or Bell-shaped, a tube whose length is not more 

 than twice the breadth, and which expands gradually from base to apex. 

 Ex.: Canterbury Bell, Harebell. 



Urceolate, or urn-shaped, when the tube is globose in shape and 

 the limb at right angles to its axis, as in the ofladal Uva Ursi, Chimaphila 

 and Gaultheria. 



The Andrcecium, or Stamen System.— The Stamens or micro- 

 sporophylls are the male organs of reproduction, and each complete 

 stamen consists of a filament, or stalk, and an anther, or pollen sac, 

 which is the essential portion and contains a powdery substance called 

 pollen.
