42 NATURAL HISTORY OF PLANTS. 



caducous. Stamens 5, alternipetalous, inserted between as many 

 oppositipetalous lobes of the disk, very perigynous ; filaments free ; 

 anthers introrse cordately 2-dymous, 2-rimose. Germen inserted 

 at bottom of receptacle, inferior at base only, otherwise free; 

 cells 5, alternipetalous, more or less incomplete ; ovules in each 

 2, basilar ; style cylindrical, apex divided into 5 short stigmatose 

 branches. Fruit inferior, crowned with calyx, dry or crustaceous, 

 indéhiscent, 1-spermous; testa of exarillate seed membranous; 

 albumen scarce ; cotyledons of straight embryo oblong. — Very ramose 

 (ericoid) shrubs ; leaves (evergreen) alternate closely packed small 

 coriaceous enervate subsessile ; stipules minute glanduliform, cadu- 

 cous ; flowers l in compound terminal racemes ; pedicels articulate, 

 bracteolate under the apex. 2 (Texas, North Mexico?) 



27. Glossopetalon A. Gray. 4 — Flowers hermaphrodite; receptacle 

 lined with thin glandulous cupular 10-crenate disk. Sepals 5, short 

 persistent. Petals 5, alternate, muchlonger, linear ligulate, marcescent. 

 Stamens 10, 2-seriate ; filaments inserted in hollows of disk peri- 

 gynous, short free; anthers short introrse. Germen free, im- 

 mersed at base in central disk, 1-locular ; style very short, apex 

 capitellate 5 stigmatose; ovules 2, subbasilar suberect ; micropyle 

 extrorsely inferior. Fruit dry coriaceous (finally 2-valvatc ?) 

 obliquely ovoid apiculate, much striated longitudinally ; seeds 1, 2, 

 ascending; funicle short dilated to a small 2-lobed aril ; testa short ; 

 embryo.,.? — An extremely ramose and spinose glabrous shrub; 

 branches punctuiate ; leaves alternate small entire subspathulate, 

 exstipulate ; floral leaves squamiform ; petiole much dilated at base ; 

 flowers axillary pedunculate, bracteate at base. (Texas, Neio 

 Mexico?} 



28. Canotia Tour. 8 — Flowers regular hermaphrodite. Calyx 

 small, glandulously decurrent at base, 5-fid, valvate, persistent. 

 Petals 5, sessile, imbricated. Stamens 5, alternipetalous, hypo- 

 gynous ; filaments free subulate, persistent ; antbers cordate shortly
