PART III. — THE CLASSIFICATION OF PLANTS. 



staminal whorl opposite to the sepals is suppressed, and there are 

 5 antipetalous staminal bandies ; anthers 4-loeular, opening by 

 pores or valves : gynaecenm usually completely synearpous ; style 

 1 ; ovary usually 5-localar, each loculus containing two ovules ; 

 but the fruit is generally only one-seeded. Mostly trees or 

 shrubs : leaves alternate, stipulate. 



The only indigenous genus is Tilia, the Lime-tree. It has oblique leaves with 

 deciduous stipules ; the annual shoots have not a terminal bud. The inflor- 

 escence is cymose, few- flowered : the. 

 peduncle is adnate to the leafy bract ; 

 this is brought about in the following 

 manner : in the axil of the leaves 

 there is usually a bud, together with 

 an inflorescence (Fig. 412) : the bract 

 (Fig 412 h) and the bud-scale, which 

 is opposite to it, are the first two 

 leaves of the axillary shoot which is 

 terminated by the inflorescence, the 

 peduncle of which is adnate to the 

 bract for some distance : the bud is a 

 winter-bud developed in the axil of 

 the above-mentioned bud-scale. The 

 inflorescence itself terminates in a 

 flower ; other flowers are borne in the 

 axils of its two bracteoles, and other 

 flowers again may be developed in the 

 axils of their bracteoles, and so on. 

 T. platyphyllos, the large-leafed Lime, 

 hag a few-flowered inflorescence, and 

 leaves which are bright green and 

 downy on the under surface : T. cor- 

 data has an inflorescence which con- 

 sists of a large number of flowers, and 

 has small leaves which are bluish- 

 green and pubescent with red hairs on 

 the under surface. T. vulgaris is the 

 common Lime. In the American 

 species the innermost stamens are 

 staminodia. Corchorus, in the East 

 Indies, yields Jute, which consists of 

 the bast- fibres. 



Fio. 412.— Inflorescence of the Lime, Tilia 

 platyphyllos: a branch; h petiole with 

 axillary bud. Attached to the peduncle is 

 the bract (h) : k calyx; c corolla; 8 stamens; 

 /ovary; fcn flower-bud (nat. size). 



Order 2. Sterculiace^e. 

 Calyx gamosepalous : androecium obdiplostemonous ; the stamens 

 which are opposite to the petals are 5 or multiple, sometimes 

 more or less monadelphous ; those which are opposite to the
