stamens and perianth). Stamens all fertile, or accompanied by 

 staminodes, interposed or peripheral. — (15 genera.) 



IV. LACiSTEMEiE. — Flowers hermaphrodite, apetalous, amenta- 

 ceous with one simple fertile stamen. — (1 genus.) 



V. CalanticEjE. — Flowers hermaphrodite, provided with petals 

 equal to the sepals or shorter, the same or double in number. 

 Stamens superposed to the petals, sometimes separately, sometimes 

 in phalanges. Gynseceum free, superior. — (3 genera.) 



VI. HoMALiE^a. — Flowers hermaphrodite, with petals and sta- 

 mens disposed as in Calanticece, but with a concave obconical recep- 

 tacle, in the cavity of which the ovary is inserted. Fruit dry, 

 capsular, " adherent." — (2 genera.) 



VII. Pangie^e. — Flowers dioecious, with concave receptacle. 

 Sepals hypogynous, valvate, or imbricated. Petals imbricated, pro- 

 vided within with a blade or glandular plate, free or adhering for 

 a variable distance to their inner face. Stamens definite or inde- 

 finite in number. Fruit generally indehiscent, fleshy, or coriaceous, 

 often voluminous, rarely capsular and dehiscent at the apex. — (6 

 genera.) 



VIII. PArAYE^E. — Flowers unisexual or polygamous, with convex 

 receptacle. Perianth double. Corolla inappendiculate, dissimilar 

 in the two sexes, tubular below and gamosepalous in the male flowers, 

 polypetalous in the female. Androceum diplostemonous, inserted on 

 the corolla. Gynseeeum superior. Fruit fleshy. — (1 genus.) 



IX. Turnere^e. — Flowers hermaphrodite. Perianth tubular 

 (receptacle ?). Petals (rarely appendiculate) inserted at the throat 

 and perigynous. Androceum isostemonous. Stamens inserted with 

 the petals (and perigynous), or more or less low until below the ovary 

 (hypogynous). Ovary free, trimerous. Styles distinct, simple or 

 divided at the summit. Fruit capsular. Seeds arillate. — (1 genus.) 



X. Cochlosperme^e. — Flowers hermaphrodite, with convex recep- 

 tacle, diperianthous. Petals developed, inappendiculate, contorted. 

 Stamens hypogynous, equal or unequal, indefinite in number. 

 Anthers linear, opening at the summit by pores or short clefts. 

 Gynaeceum free, with partitions more or less incomplete or almost 

 complete. Fruit capsular, with the exocarp separate from the endo- 

 carp, and opening into valves alternate with those of the endocarp. 

 Seeds incurved or spiral, piliferous, operculate in front of the sum- 

 mit of the fornicate embryo. — (1 genus.)
