rurved; flowers smaller; stem erect or ascending, densely pubes- 

 cent; calyx pubescent F. serpyllif olia. 



b. Leaves sessile, linear, short; flowers in dense heads (aggregated 

 cymes) at the top of the branches, rather small; stem, leaves and 

 calyx puberulous F. conferta. 



B. Placentas parietal, each bearing 1 — 2 ovules; stems decumbent; flowers 

 small, solitary or in dichotomous cymes. 



a. Stems quite glabrous; leaves linear-terete, distinctly petiolate: flowers 

 solitary F. Drummondii. 



b. Stems more or less puberulous; leaves subsessile or sessile; flowers 

 in leafy dichotomous cymes. 



1. Calyx more or less imbedded in a sheath formed by 4 floral 

 leaves, glabrous; stems sparingly puberulous, lower leaves oblong- 

 ovate, floral leaves triangular-ovate F. ambit a. 



2. Calyx sessile (not imbedded), with 4 linear floral leaves, hairy; 

 stems densely hairy with a short pubescence; leaves linear-terete. 



F. Maidenii. 



C. Ovules 2— 3, basal, on long funicles. 



a. Flowers in dense heads (contracted cymes) at the top of the branches; 

 leaves distinctly petiolate with ciliate sheaths; stems erect, inter- 

 nodes much longer than the linear-terete, glabrous, revolute leaves. 



1. Floral leaves ovate-lanceolate, flat and strongly ciliate, much 

 broader than the stem-leaves F. bracteata. 



2. Floral leaves like the stem-leaves, linear-terete. 



t Glabrous or nearly so F. glomerata. 



ft Branches, young leaves and calyx hairy with short bristly 

 hairs F. setosa. 



b. Flowers solitary or in leafy dichotomous cymes at the top of the 

 branches; stems decumbent (or rarely erect?). 



1. Leaves sessile, shortly linear-terete (under 5 mm long); stems 

 decumbent; flowers small. 



t Leaves not produced below their insertion, acute or obtuse; 



stamens 4, style 2-cleft, ovules 2 F. tetr apetala. 



tt Leaves produced below their insertion into a free, closely ad- 

 pressed appendage; stamens 6, style 3-cleft, ovules 3 (2—4?). 



F. punctata. 



2. Leaves distinctly, but often minutely petiolate on the margin of 

 the sheath. 



t Leaves very short (not exceeding 2 mm), terete-oblong, much 

 revolute, obtuse, glabrous; sheath rather long (half as long 



as the blade), with strong cilia F. p arvula. 



tf Leaves longer (3—6 mm); sheath much shorter than the blade. 

 o Leaves more or less hairy on the upper surface; branches 



and calyx densely hairy F. Interioris. 



oo Leaves glabrous on the upper surface; branches sparingly 

 pubescent; calyx glabrous. 



+ Leaves oblong, flat with revolute margins and densely 

 hairy lower surface; internodes much shorter than the 



leaves; styles 3, ovules 3 F. compacta. 



++ Leaves linear, revolute ; internodes longer than the leaves ; 

 styles 2, ovules 2 F. Georgei.
