and the throat having a yellow stripe on its inside. The calyx 

 has a kind of involucre formed of two large membranous 

 bracts, of a pale pink color. M. longiflora is a native of the 

 Cape of Good Hope, and its flowers are very long and purple, 

 The Order Pedalinea, or the Oil-seed Tribe, to which this 

 genus belongs, takes its name from the genus Pedalium. All 

 the plants of this Order agree in possessing seeds which con- 

 tain an abundance of oil. The genus Scsamum produces a seed 

 which is much used in the Levant, and also in Africa, as an 

 article of food, and an oil is pressed from it which is used on 

 salads, and for all the purposes of sweet oil. A species of this 

 is the " Open Sesame," which every reader of the story of the 

 Forty Thieves in the Arabian Nights, will remember.

 but may always be distinguished by their long, horn-like pods, 

 and their stigma, which, instead of radiating into numerous 

 divisions over the top of the ovary, forming so elegant a feature 

 in the fructification of the common Poppy, is simply divided 

 into two plates or lamellae. We shall see how these pods, as 

 well as the capsules of the Poppy, are formed, when we 

 describe the Order Papaveracea. 



The species in our plate is the one common on the sea side 

 in England, and from the blue tint of its stem and leaves.

 incrusted itself upon its skin." It becomes, in favorable situa-
