CXXVIII. TREMANDREiE. 



Tremandre.?:, R. Broton in Flinders, p. 12. (1814) ; Dec. Prodr. I. 343. (1824.) 



Diagnosis. Polypetalous dicotyledons, with 8 or 10 hypogynous 

 distinct stamens, concrete carpella, a 2-ceiled ovarium with a definite 

 mimber of pendulous ovules, a calyx with valvate aestivation, anthers 

 bursting by pores, and entire petals involute in aestivation. 

 Anomalies. 



Essential Character. — Sepals 4 or 5, equal, with a valvular aestivation, slightly 

 cohering at the base, and deciduous. Petals equal in number to the sepals, with an invo- 

 lute aestivation, enwrapping the stamens, much larger than the calyx, and deciduous. 

 Stamens hypogynous, distinct, 2 before each petal, and therefore either 8 or 10 ; anthers 

 2- or 4-celled, opening by a pore at the apex. Ovarium 2-celled ; ovules from 1 to 3 in each 

 cell, pendulous; style I; stigmas I or 2. Fruit capsular, 2-celled, 2-valved ; dehiscence 

 loculicidal. Seeds pendulous, ovate, with a thickened appendage at the apex, but with no 

 appendage about the hilum ; embryo cylindrical, straight, in the axis of fleshy albumen ; the 



radicle next the hilum Slender heath-Uke shrubs, with their hairs usually glandular. 



Leaves alternate or whorled, without stipulaj, entire or toothed. Pedicels solitary, axiUary, 

 1 -flowered. 



Affinities. Not very certain ; many genera probably still remain to 

 be discovered. According to Decandolle, they are related to Polygaleae ; 

 from which they differ in a number of points, especially in their distinct 

 stamens and regular flowers; agreeing with them in having a remarkable 

 tumour, called a caruncula, at one end of the seeds, which are also definite 

 and pendulous in both orders. 



Geography. All natives of New Holland, 



Properties. Unknown. 



Examples. Tetratheca, Tremandra. 



CXXIX. POLYGALEiE. The Milkwort Tribe. 



POLYGALE.K, Juss. Ann. Mus. 14. 386. (1809) ; Mem. Mus. 1. 385. (1815); Dec. Prodr. 

 1. 321. (1824) ; Lindl. Si/nops. 39. (1829) ; Any. de St. Ililaire and Moquin-Tan- 

 don Mem. Mus. 17- 313. (1829.) 



Diagnosis. Polypetalous dicotyledons, with definite hypogynous sta- 

 mens in one parcel, concrete carpella, an ovarium of 2 cells with the 

 placentae in the axis, an imbricated calyx, unsymmetrical flowers, definite 

 pendulous ovules, and dehiscent fruit. 



Anomalies. Sepals 4, and all petaloid in some Kramerias. Flowers 

 generally monopetalous. Ovarium sometimes 1 -celled by abortion. Fruit 

 indehiscent in Mundia, Monnina, Securidaca, and Krameria. The latter 

 has also no albumen. Stamens distinct in Krameria. 



Essential Character — Sepals 5, very irregular, distinct, often glumaceous ; 3 

 exterior, of which 1 is superior and 2 anterior; 2 interior (the wings) usually petaloid, and 

 alternate with the upper and lower ones. Petals hypogynous, usually 3, of which 1 is 

 anterior and larger than the rest {tlic keel), and 2 alternate with the upper outer, and 

 lateral inner sepals, and often connate with the keel ; sometimes 5, and then the 2 addi- 

 tional ones minute and between the wings and the lower sepals. Keel sometimes entire, 

 and then either naked or crested ; sometimes 3-l()be(l, and then destitute of a crest. A7a- 

 OTCMs hypogynous, 8, usually combined in a tube, uneipial, and ascending; sometimes 4, 

 and distinct; the tube sjilit opposite the uj)per sepal; anthers clavate, innate, mostly 1- 

 celled and opening at their apex, sometimes 2-teIled ; very rarely the dehiscence is lougi-
