NATURAL niSTOBY OF PLANTS. 



3G. Guichenotia J. Gay. 1 — Flowers nearly of Lasiopetalum ; 

 calyx 5 -fid after anthesis, membranous, dilated ; sepals finally 

 elevate-3— 5-ribbed. Petals squamiform. Stamens 5, oppositipetalous ; 

 anthers dehiscing by short clefts. 2 Ovary cells 5, 2- or few-ovulate ; 3 

 style entire, upper part bare or stellate-pilose. Capsule loculicidal. 

 Other characters as in Lasiopetalum. — Small tomentose shrubs ; hairs 

 often stellate ; leaves alternate, generally entire, narrow, recurved at 

 margin; stipules? lateral, leaf-shaped; flowers solitary or in falsely 

 racemose 1 -lateral cymes 4 {Extra-tropical Australia 6 ). 



37. Lysiosepalum F. Muell. 6 — Sepals 5, valvate immediately 

 before anthesis, free at base. Petals 5, minute, squamiform. Stamens 

 5, oppositipetalous ; anthers linear, cells shortly rimose at apex. 

 Grermen 3-locular ; ovules oo ; style glabrous. Capsule loculicidal, 

 3-valved. — A shrub, with stellate velvety hairs ; leaves oblong- 

 linear, revolute at margin ; stipules small or ; flowers 7 racemose, 

 included in valvate involucre of thick bracts {South Western Aus- 

 tralia*) . 



38. Thomasia J. G-ay. 9 — Calyx nearly of Lasiopetalum ; sepals 

 coloured or transparent, finally membranous-dilated. Petals very 



Fl. Fit., 25, t. 5) is said by more recent authors (B. 

 H., Gen., 984, n. 40 a) to be a " Genus evidenter 

 Lasiopetalo valde affine, nee nisi capsulis echin- 

 atis ditferre videtur." Cui : " calyx 5-tidus, 

 laciniis obovatis obtusis. Petala minuta squama> 

 iormia cordata. Stamina antberifera 5, libera, 

 calycis laciniis alternata ; anthera? 2-rimosa3. 

 Staminodia 0. Ovarium 5-loculare ; loculis 1- 

 ovulatis; stylo. . . Capsula setis flaccidis ecbinata. 

 Semina solitaria adscendentia. — Arbor ; raunulis, 

 foliis inflorescentiaque ferrugineo-stellato-touien- 

 tosis. Folia alterna, ovato-oblonga v. obovata, 

 integerrima corincea, supra demum glabrata. 

 C\ mae pauciflorae. Spec. 1. P. rhamnoides 

 Seem., ins. Fidji incola." A plant imperfectly 

 known. In habit and number of ovules iU 

 seems to differ much from other Lasiopetalm. 

 Perhaps allied to Maxwellia ? Its place re- 

 mains very doubtful.

2 Anthers appear generally exirorse: furrows 



slightly below apex seeking internal face, and 

 there only dehiscing. 



3 Exostome thickened in flower.
