THE MYRSINE FAMILY 



MYRSINACE^ Lindley 



HIS family comprises about 30 genera, including some 475 species of 

 trees or shrubs of the tropical and subtropical regions of both hemi- 

 spheres. They are of very little economic importance, a few producing 

 edible fruits and several are cultivated in conservatories for ornament, 

 the best known, perhaps, being the Ardisia, Ardisia crenata Sims, a beautiful dark- 

 green foliaged shrub, with brilHant scarlet fruit, for which it is much admired, 

 especially if well grown, and popular for Christmas decoration. 



The Myrsinaceae have mostly alternate, simple, leather}^, punctate leaves with- 

 out stipules. The inflorescence is racemose, cor}'mbose, or clustered on scaly 

 spurs; the flowers are regular, perfect, or polygamo-dioecious ; the inferior calyx 

 consists of 4 to 6 or rarely more, persistent, usually glandular sepals; the corolla 

 is flat, salverform, or wheel-shaped, the tube very short, the lobes spreading, re- 

 flexed, or curled back, often glandular hke the calyx; stamens 4 to 7, opposite the 

 corolla-lobes and joined to the base or the tube of the corolla; filaments some- 

 times united into a tube; ovary of 4 to 7 united carpels, i-celled, the styles united; 

 stigma capitate. Fruit a dryish drupe, often leatheiy, globular, rarely obovoid, 

 often tipped by the style; seeds soHtar)-, entirely fifling the cavity, often lobed at 

 the base; endosperm copious, surrounding the embr}-o. 



Two genera, each represented by a single species, occur in southern Florida. 



Stamens joined to the base of the corolla-lobes; anthers blunt; flowers lateral. i. Rapanea. 

 Stamens joined to the throat of the corolla-tube; anthers acute; flowers terminal. 2. Icacorea.
