The two carpels have a common partition or placenta which is 
membranous in texture, and which is termed the Beplttm. The grtn*l valves of tike 
carpels open upwards and expose the seeds, which are attached to the replum. 
This form of fruit, which is usually more or less linear in shape, is termed jfte 
SKfua, and is characteristic of the Cmciferae, cjf.. Wallflower, Radish. 
The term of Sdicvia (diminutive of Sfliqua) is applied when the froh is as broad 
as long, tjg., Shepherd's Purse (CapseUa Bmsa-pastons). 
Cmptwlc This is a dry synearpous fruit, not previously enumerated, and 
suaDy opening ItmgibtdinaUy. 
The slrfcs may proceed front ife apex to the base of the fruit, or may be confined 
to the upper pare, in which case the separare valves are tooth-like. 
Capsules may be winged, as in Hop-bush (Dodotuea). Sometimes they are 
covered with setae as in certain StereuEaceae. t.g.. Commtnomia. 
In Sy*tarpta lavnfolia (Turpentine), see Plate 3. Part I., we have a capsule 
opening in valves, the capsules connate by their calyces. 
In the Grass Trees (Xan&orrkaa) the fruit forms a brown, shining, dry, 
membranous capsule, with & few black flat seeds. 
In the capsule we can have three kinds of spotting or dehiscence : 
(a) Sfpticidal, when it takes place along the ventral sutures. Example, Flindfrtia, 
where there are five boat-shaped valves, bearing blunt prickles. 
(6) ZocWirWnf, when it takes place along the dorsal sutures. Examples, Pitto- 
tfontm; Sy*o*m gUmdHlontm (Fake Rosewood): C*pa*ia ; DorymOu* 
(Gymea or Giant Lfly) : 7n>. 
(c ) Sfptifragol. when the valves separate from the paithions (dissepiments) of the 
ovary, tJ.. Thom Apple (Datum Stramonium). 
TW fVp" u may open by pores or small apertures in the pericarp, when the 
dehiscence is said to be porous , e.g.. Poppy (Paparrr) ; Snapdragon (Antirrhinum). 
Cases of partial dehiscence. when h only takes place at the top of the capsule, 
tke valves being indicated by teeth, ejg., certain Chick weeds (SieOaria) ; Primula ; 
but especially in Eucnlypt**. 
The fnrit of Eucalyptus is very important to us in AnstraHg. It consists of a 
more or less enkrged, tough leathery or woody calyx-tube, adcate* to and enclosing 
tke horny capsule. The valves or capsular teeth (i>., the tops of the capsule) somedmes 
protrude beyond the calyx-tube; in other esses they are flush with the top or sunk 
the level of the calyx-tube. The calyx-tube has usually a circular sculpture 
tamed the " rim." Ttob afawrs the original position of the opercuhnn. 
Tfce rim may, in certain species, ej., E. fenferonttf, E. aatrta, form a band 
which is re?% a porikn of the capsule which has protruded from the calyx-tube. The 
ijnif in tmjAjytm m o variable that a special chapter would be required to do it 
justice. _ _ __ __
