248 XXII. STERCVLIACE.E. ' [ITannafonUa. 



connectea iu a ring at tlie base ; aiitlier-cells parallel, opening by dorsal slits. 

 Ovary 3- or 4-ceired, with 3 or 4 ovules in each cell. Style simple. Capsiile 

 hard, almost woody, opening loculicidally in 3 or 4- valves. Seeds struplno- 

 late, albuminous; embryo straight, with flat cotyk'dons.-^Shnd>, with the 

 habit of a T/iomasia, but without stipules. Bracteoles 3, persistent. 



The genus is liinitcJ to a single species. It has the anthers of KeraJidrenia and Serifigm, 

 With the calyx nearly of Guichenotia, 



1, H. quadrivalvis, F. Muell. Fnujm. ii. 9. A much-branched shrub 

 of 3 or 4 ft., densely clothed with a soft velvety tomcntum, often rusty on 

 the young shoots. Leaves on rather long petioles, obliquely ovate-cordate, 

 obtuse, 1 to i\ in. long, coarsely sinuate-toothed or broadly lol)ed, thi^^k ana 

 soft. Cymes leaf-opposed, short, and few -flowered, l^racteoles hnear, much 

 shorter than the calyx. Calyx about ^ in. long, divided to below the middle 

 into narrow acuminate lobes. Petals about as long as the calyx-tube, but 

 variable. Staminodia in Mueller's specimens 3 between each 2 stamens, 

 but in one of Douglas's I formerly examined I found them singly alter- 

 iiatuig with the stamens. Capsule shorter than the calyx, most frequently 

 4-celled, but often also 3-celIed.

Calyx 5-lobed, much enlarged and scarious or coloured after flowering, the 

 sepals l-uerved and rcticvdatcly veined, with the midrib usually thickened, 

 spreading or erect-connivent, closing over the fruit. Petals none or minute 

 and scale-like. Stamens 5, alternate with tlic sepals, free or shortly connate 

 at the base; staminodia none, or 5 alternating with the stamens. Anthers 

 opening at the top towards tlie inside in short ^^lits, which at length extend 

 more or less down the sides. 'Ovary 3- or rarely 4- or 5-cellcd, with 2 ov 

 more ovules iu each cell; stvle simple. Capside enclosed in the calyx, 



■ '^ " Seeds usually 



more or less tomontose or hirsute v\-ith stellate hairs, rarely quite glabrous. 

 Leaves entire or lobed. Stipules leafy, usually semihastate o'r reniforn^, in one 

 species similar to the leaves, in others small, and in a i^dw entirely wantnig- 

 Racemes leaf-opposed, simple or rarely cymosely branched. Bracts narrow, 

 deciduous. Bracteoles under the calyx 3, slightly connate at the base or 

 free. Calyx usually purple bluish or white. 



Tlic genns is confined to Australia, [t differs from LashprMum more constantly i" the 

 calyx than ni the anthers, the opening of the hitler in sunn- mr.aasia^htxn^Wii^^ ^^^

 The two genera are natural, and the u.ajority of species distin*nu'shcd by a variety of ^^hn- 

 racters, although there is no one to which there is not some exception. 'I'hc presence or 

 absence and size of the scale-like pt-tals, the pruence or ahaence and nunihcr of stnniinodia, 

 are liable in all these genera to great variation in individual species.
