258 PRACTICAL BOTANY. 



854. Flowers in racemes. Stamens 2 or 3. Style 3- 

 cleft; stigmas 3, simple. Calyx of the sterile flowers 3-, 

 that of the fertile 6- (5- to 8-) parted. Tragia. 



Flowers in a terminal spike. Stamens 2. Stigmas 

 3, simple. Calyx of the sterile flowers a 2-cleft, or creuulate 

 cup, that of the fertile ones S-tooLhed. 



StiUingia sylvatica, L. 



855, Leaves alternate (at least most of them), exstipu- 

 late 826 



Leaves opposite, somewhat 3-nerved, long-petioled- 

 stipulate ; stipules united. Flowers, the sterile of 3 (or 4) 

 sepals and as many stamens ; the fertile ones of 3 sepals, 1 

 pistil, and 3 rudimentary cucullate stamens; both kinds 

 mixed in dense clusters. Filea pumila, Gray (833). 



836. Flowers 3-bracted. Sepals 3. Stamens 3 or 2. 



827 

 Flowers not 3-bracted ; the sterile with a 3- (to 6-) 

 sepalled calyx and 3 (to 5) stamens ; the fertile consisting of 

 a 2-styled ovary between 2 leaf-like bracts. Leaves triangu- 

 lar-hastate, sinuate-toothed, or nearly entire (upper ones lance- 

 olate), sometimes meally ; most of them alternate. Fruit- 

 bracts deltoid. (666) Atriplex hastata, L. (836). 



827. Fruit (utricle) opening transversely. Stamens 3 

 or 2. Stems whitish, mostly spreading next the ground. 

 Leaves spatulate-oblong, long-petioled, very obtuse, or retuse. 

 Flowers greenish, in close axillary clusters. 



(649) Amarantus albus, L. 



Fruit (utricle) indehiscent, or bursting irregularly. 



Stamens 3. Stems erect, ascending, or decumbent. Spikes 



or heads axillary and terminal. Leaves petioled, elliptic, or 



rhombic-lanceolate. (649) Euxolus. 



828. (815.) L Ovary 1-celled 829 



IL Ovary 3-celled. Styles 3, thick, subulate and 



recurved. Pod 3-horned. Calyx 4-parted. Stamens (of 

 the sterile flowers) 4, surrounding a rudimentary ovary. 

 Flowers, each 1- to 3-bracted, in a few, many-flowered spikes, 

 from near the base of the stem, the fertile below the sterile. 

 Leaves few, oval, crenate-toothed, long-petioled. 



Pachysandra procumbens, Mx.
