Cult. All the species of Callistemon are worth cultivating in 

 every collection of greenhouse plants for the neatness of their 

 foliage, and the beauty of their blossoms, but especially those 

 belonging to the last division of the genus, for the splendour of 

 their flowers, which are either scarlet or crimson ; and are there- 

 fore well adapted for a conservatory. The soil best suited for 

 them is a mixture of loam, peat, and sand. Ripened cuttings of 

 them strike root in sand, under a hand-glass. They may be 

 also raised from seeds, which are frequently produced in this 

 country on large plants. Plants raised from cuttings, taken from 

 flowering plants, come into flower when small, but those raised 

 from seeds do not flower till they become large. 



XVII. METROSIDE'ROS (from ^rpa, metra, the heart of 

 a tree, and <ric>>)poe, iron ; the wood and pith of the trees are 

 very hard). R. Br. gen. rem. p. 15. D. C. prod. 3. p. 224. 

 Metrosideros species, Gsertn. Smith and Ait Nani, Adans. 

 fam. 2. p. 88. 



LIN. SYST. Icosdndiia, Monogynia. Tube of calyx not 

 angular, adhering to the ovarium ; limb 6-cleft (f. 120. a.). Sta- 

 mens 20-30, free, very long, and exserted. Style filiform ; stigma 

 simple. Capsule 2, but usually 3-celled ; cells many-seeded. 

 Seeds wingless. Trees or shrubs. Leaves opposite or alternate. 

 Flowers pedicellate, not adnate to the branches, as in the genus 

 Melaleuca and Callistemon. The genera Angophora and Cal- 

 listemon have been separated from Metrosideros as it formerly 

 stood ; these genera are very natural, but the present genus requires 

 to be still further divided into other genera, for as it now stands 

 it is a heterogeneous mass of plants ; but from the fruit of the 

 greater part of the species being unknown, this is altogether im- 

 practicable at present. 



* Leaves opposite. 



1 M. VE'RA (Rumph. amb. 3. p. 16. t. 7. Lindl. coll. t. 18.) 

 leaves opposite, on short petioles, ovate-lanceolate, acuminated, 

 quite glabrous ; cymes axillary, pedunculate, many-flowered.

 sest. ind. 220. t. 53. ex Rumph. Eugenia Amboynensis, Hort. 

 Flowers yellow. Stamens 30. Ovarium 2-celled. This spe- 

 cies differs from all the others in habit, and is probably the only 

 true species of Metrosideros. The Chinese make rudders and 

 anchors of the wood ; and among the Japanese it is very scarce 

 and valuable. The bark is used as a remedy for fluor albus and
