dilated below and there enclosing gerraen adnato within, higher pro- 

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

 at the margin the perianth and the stamens. Sepals 5, obtuse or 

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

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

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

 indéhiscent ; seed 1 ; cotyledons of straight exalbuminous embryo 

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

 etc., of G 'alythrix. 1 (Australia. 2 ) 



45. Calythrix Labill. 3 — Flowers (nearly of Lhotzkya) ; receptacle 

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

 larly dilated and bearing perianth inserted on margin. Sepals 4 5, 

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

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

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

 perianth, unequal ; 5 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 anatroj>ous ; micropyle introrsely 7 in- 

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

 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 8 axillary or capi- 

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

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

 scarious, imbricate. 9 (Australia.™)
