POLYANDRIA. 165 



GENUS Bixia, Arnotto Tree. This tree grows in the 

 West Indies, and rises to the height of twenty feet. The 

 Arnotto, a paint with which cheese and butter are colored, 

 is prepared from the pulp which covers the seeds of this 

 plant. The fruit being macerated in hot water, the seeds are 

 separated, and the remaining pulp being purified, and the 

 water evaporated, forms the coloring substance in question. 

 The natives of hot climates use pieces of this wood to obtain 

 fire by friction. The Lime, or Linden tree, known also by 

 the name of Basswood, the Tilia of Botanists, belongs here. 

 Also the Peony, and Cistus, or Rockrose. 



ORDER II. DI-PENTAGYNIA. Stamens many. Styles 2-5. 



We had occasion to explain the name of this order undei 

 the head of Icosandria, where it is employed as well as here. 



In the original Linnaean arrangement, the orders Digynia, 

 Trigynia, and Tetragynia, were used instead of Di-Penta- 

 gynia. But the styles from Digynia to Pentagynia inclusive, 

 being from two to live, these orders are now embraced in the 

 present one. 



GENUS Delphinum. Larkspur. Name, from the Greek, 

 delphin, a dolphin, on account of the resemblance of the nec- 

 tary of this plant to the imaginary figures of that fish. The 

 species are well known annual, or perennial plants, all of 

 them either blue, purple or red, but never yellow. This genus 

 has no calyx ; the petals are five, and unequal. The appen- 

 dage called the spur, or nectary, is common to all the species. 



The Aconitum, or Wolf's bane, all the species of which 

 are poisonous to a high degree, belongs here. This is also 

 the place oi'the Columbine, (Aquilcgia,) a common, hardy, 

 perennial, herbaceous plant, which springs up early in the 

 spring, and continues to flower from May to July. 



ORDER III. POLYGYNIA. Stamens many. Styles many. 



GENUS Liriodendron. Tulip tree. Name from the Greek, 

 leiriofi, a lily, and dendron, a tree. This is a native of North 

 America, and is among the tallest and most beautiful of our 

 forest trees. The flowers are produced at the ends of the 

 branches, and resemble the tulip, rather than the lily. The 



How is arnotto obtained 1 What is said of the Larkspur "? Whence 

 comes the name of the genus Liriodendron 1
