XIV. CODIES. 



82. Codia Forst. — Flowers capitate hermaphrodite regular ; 

 receptacle concave obconical. Sepals 4, or more often 5, inserted in 

 mouth of receptacle, valvate. Petals as many, alternate linear very 

 narrow, or 0. Stamens 8-10, inserted with perianth; filaments 

 free; anthers 2-dymous, introrse or laterally rimose. Germen 

 altogether or almost wholly inferior ; cells 2, complete or incom- 

 plete ; styles 2, diverging, stigmatose at apex. Ovules 2 in each 

 cell, collaterally descending, anatropous; micropyle extrorse superior. 

 Fruit nucamentaceous. Seed 1, descending ; albumen fleshy thin 

 cotyledons of axile embryo leafy ; radicle short superior. — Shrubs 

 leaves opposite simple coriaceous petiolate ; stipules large caducous 

 capitula globose pedunculate axillary, at base involucrate by (usually 

 4) bracts; single flowers bracteate {New Caledonia). See p. 379. 



83. Pancheria Br. & Gr. — Flowers dioecious, 3-5-merous ; calyx 

 imbricate. Petals equal or unequal, scarious. Stamens G-10, of 

 Codia (sterile in male flower). Germen superior (rudimentary in 

 male flower) ; carpels 2, nearly free, tapering to simple styles ; 

 placenta involute, 2-ovulate. Ovules inserted a little above base of 

 germen, collaterally descending ; raphe extrorse by involution of 

 placenta; micropyle introrse superior. Follicles 2, dehiscent within; 

 edges very much involute. Seeds 1, 2, descending ; albumen and 

 embryo of Codia ; micropyle superior, produced to a membranous 

 wing. — Shrubs ; leaves 3-5-nately verticillate serrate ; stipules 

 caducous ; capitula of Codia {New Caledonia). See p. 379. 



84. Callicoma Andr. — Flowers hermaphrodite, nearly of Codia ; 

 calyx 4, 5-merous coloured, valvate. Petals 0. Stamens 8-10, 

 inserted with calyx in mouth of hardly concave or obconical recep- 

 tacle ; filaments long-exserted. Germen free to a great extent or to 

 middle ; cells 2, or more rarely 3, complete or incomplete ; ovules 

 oc ; styles 2, 3, much elongated, circinate in bud, afterwards 

 straight, long-exserted, Capsule more or less included in calyx, 

 septicidally 2, 3-valved ; endocarp chartaceous, seceding from meso- 

 carp. Seeds 1, or few ; testa crustaceous papillose ; embryo small
