dilated below and there enclosing germen adnata -within, higher pro- 

 duced to a long tubular neck and at apex dilated to a cupule bearing 

 at the margin the perianth and the stamens. Sepals 6, obtuse or 

 retuse, not aristate. Petals 5. Stamens oo , oo -seriate. Germen 

 inferior, 1-locular; ovules 2, ascending, inserted on placenta extend- 

 ing from base to apex of cell. Fruit dry, crowned with calyx, 

 indehiscent ; seed 1 ; cotyledons of straight exalbuminous embryo 

 minute. — Ericoid shrubs; alternate and sometimes opposite leaves, 

 etc., of Galythrix.^ {Australia?) 



45. Calythrix Labill.^— Flowers (nearly of i7iofe^2/a) ; receptacle 

 long lageniform ; neck sometimes very narrow tubular, above cupu- 

 larly dilated and bearing perianth inserted on margin. Sepals* 5, 

 patent, scarious at margin and mucronate or oftener far produced to 

 a setiform arista. Petals 5, entire, deciduous. Stamens oo (often 

 25-30), 00 -seriate; the interior shorter; filaments inserted with 

 perianth, unequal ;' anthers short introrse, versatile. Germen inferior, 

 adnate within to receptacle, 1-locular ; placenta springing from dis- 

 sepiform bottom of germen and extending to its apex. Ovules 2, 

 subbasilar, collaterally erect anatropous ; micropyle introrsely ''' in- 

 ferior. Fruit often crowned with calyx and receptacle, dry, inde- 

 hiscent. Seed 1, erect; cotyledons of thick straight embryo very 

 short. — Ericoid shrubs or undershrubs ; leaves alternate, semiterete 

 or 3-4-quetrous, articulate at base and there sometimes furnished 

 with 2 minute linear caducous stipules ; flowers^ axillary or capi- 

 tately corymbose at summit of twigs ; floral leaves often changed to 

 bracts; bracteoles 2, lateral, persistent, subfoliaceous or often 

 scarious, imbricate.' {Australia}")
