11. LEPTOSPERME^. 

 20. Leptospermum Foest. — Flowers hermaphrodite or more 

 rarely polygamous; receptacle depressed ohconical or turbinate, at base 

 covering germen adnata within. Sepals 5, marginally inserted, im- 

 bricate, often at last not contiguous. Petals 5, alternate, imbricate, 

 finally patent. Stamens cx) , when adult apparently 1-seriate, shorter 

 than or subequal to petals ; filaments unequal, dilated at base ; anthers 

 small introrse, yorsatile ; cells parallel, longitudinally rimose. Ger- 

 men adnate to receptacle within, inferior or partly free, plane or 

 convex at vertex, radiately sulcate and glandular or impressed ; cells 

 3-5, or more rarely 6-12 (sometimes effete) ; style central, short or 

 elongate, capitate or peltate at stigmatose apex. Ovules in cells go 

 (sometimes few), inserted on 2-lamellate short or more or less promi- 

 nent sometimes vertically 2 -seriate, sometimes transverse or more or 

 less obliquely peltate placenta, horizontal or descending, sometimes 

 recurved. Capsule girt with adnate receptacle, enclosed or exserted 

 above, loculicidal. Seeds in cells l-oo (mostly sterile), either linear, 

 or cuneate-angular, in some cases naked, in others ciliate or alate at 

 margins or angles ; coat thin ; cotyledons of straight exalbuminous 

 embryo longer than radicle. — Small trees or oftener shrubs glabrous 

 or incanescent, odorous; leaves alternate exstipulate small rigid 

 pellucid-punctate, 1-3-nervedor veinless; flowers axillary or terminal, 

 solitary or 2-3-nate, sessile or shortly pedicellate; bracts rather 

 broad, imbricate, falling before anthesis ; bracteoles smaller, sometimes 

 longer persistent. {Tro^, Oceania^ Australia^ New Zealand.) — See 

 p. 314. 



21 ? Agonis DC.^ — Flowers nearly of Leptospermum, stamens 10, 

 2-seriate or co . Germen, etc., of Leptospermum; ovules in cells 2-4, 

 inserted on ascending more or less dilated placenta and suberect ; 

 micropyle inferior. — Shrubs or small trees ; leaves alternate, oftener 

 narrow ; flowers capitate ; capitules axillary and terminal globose, 

 densely glomeruliferous; each flower 2-bracteolate.^ (West. Aus- 

 tralia.^)
