3a. GALENIA L. 



Herbs or shrubs, with spreading or prostrate branches, the foliage glabrous, pubescent 

 or scaly. Leaves opposite or alternate, often very variable in size. Flowers perfect, in- 

 conspicuous, axillary. Sepals 4 or 5. Stamens 8 or 10, in pairs at the sinuses of the 

 perianth. Ovary 3-5-celled, or 1-celled by abortion, often depressed at the apex. Styles 

 erect. Ovules pendulous. Capsule 3-5-angled, leathery. 



1. Galenia secunda Sond. Stem branched at the base, the branches radially spread- 

 ing, several dm. long, much branched : leaves numerous ; blades rhombic, cuneate-obo- 

 vate or spatulate-obovate, mainly 1-2 cm. long : calyx about 3 mm. long ; lobes oblong or 

 lanceolate-oblong, ciliate near the tip and pubescent without : filaments shorter than the

4a. DITHYRAEA Harv. 



Herbs, with stems often branched at the base. Leaves alternate, often mainly basal : 

 blades sinuate or pinnatifid. Flowers in terminal racemes. Sepals narrow, deciduous.

 margined, each cavity ] -seeded. 



1. Dithyraea Wislizeni Engelm. Stem 2-6 dm. tall, closely pubescent, often 

 branched at the base, the branches ascending or spreading, rather copiously leafy : leaf- 

 blades lanceolate, varying to ovate-lanceolate or linear-lanceolate, 3-8 cm. long, or shorter 

 near the inflorescence, sinuate or pinnatifid, those of the lower leaves narrowed into petiole- 

 like bases, those of the upper merely sessile : racemes becoming 1-4 dm. long and lax at 

 maturity : pedicels elongating, reflexed at maturity : sepals linear or linear-lanceolate, 

 3.5-4.5 mm. long, ciliate : petals 6-7 mm. long, the blades suborbicular, longer than the 

 claws : pods 12-14 mm. wide, notched at the base, finely pubescent.
