LINDEN FAMILY. 91 



M. verticil/ata, Linn. (Sometimes called M. odorXta.) Cult, from 

 Cape of Good Hope, in ronservatories, producing;- a succes.sion of honey- 

 yellow, sweet-scented .small blossom.s, on slender peduncles, all winter and 

 spring ; a sort of woody perennial, with slender and spreading or liang- 

 ing roughisli branches and small irregularly pinnatitid leaves ; the specilic 

 name given because the leaves seem to be wliorled ; but this is because 

 the stipules, which are cut into several linear divisions, imitate leaves. 



XXIII. TILIACEiE, LIXDEN FAMILY. 



Trees (rarely herbs) with the mucilaginous properties, 

 fibrous bark, valvate calyx, etc., as in the Mallow Family ; but 

 sepals deciduous ; petals imbricated ; stamens in several clus- 

 ters, and anthers 2-celled. Chiefly a tropical family, repre- 

 sented here only by an Iierbaceous Corchorus on our 

 southernmost borders, and by the genus of fine trees which 

 gives the name : 



1. TILIA, LINDEN, BEE TREE, BASSWOOD. (The old Latin 

 name.) Sepals 5; petals 5, spatulate-oblong. Stamens numerous; 

 their lilaments cohering in 5 clusters or with a petal-like body before 

 the true petal. Ovary 5-celled with 2 ovules in each cell ; fruit rather 

 woody, globular, 1-2-seeded. Style 1. Stigma 5-toothed. Trees with 

 tough inner bark {bast), soft white wood, alternate roundish and serrate 

 leaves more or less heart-shaped, and commonly oblique at the base, 

 deciduous stipules, and a cyme cif .small, dull cream-colored, honey- 

 bearing flowers, borne in early summer on a nodding axillary peduncle 

 which is united to a long and narrow leaf-like bract. (Lessons, Figs.
