Some important floral characters of the family are:



Plant parts often mucilaginous, leaves stipulated, young stem/ branches often with stellate trichomes


Flowers axillary, solitary, or in fascicles, racemes or panicles, actinomorphic, usually bisexual, pentamerous.


Calyx, free or connate, valvate aestivation


Corolla free, adnate at the base to the staminal tube and falling off with it, twisted; petals 5.


Stamens usually numerous, monadelphous to form staminal tube which at apex divided into numerous filaments


Carpels 1 to many, usually in a single whorl, placentation axile; style usually branched into as many as the number of carpels or 


sometimes twice the number of carpels


Fruit a dry capsule or schizocarp, rarely baccate, usually dehiscent.


Seeds with a little endosperm


Genera represented in India include Hibiscus, Pavonia, Thespesia,  Kydia, Gossypium,  Alcea, Malva,  Abutilon,  Malvastrum,

Latest developments in the family
For all Details please see the paper attached

Excerpts from this paper:

In the broader APG circumscription, Malvaceae s.l. corresponds to
the four traditional plant families Malvaceae s.s., Bombacaceae,
Sterculiaceae and Tiliaceae (Table 2). Thus, the family has expanded to
include 250 genera and has been divided into nine subfamilies, one of
which is Malvaceae s.s.[4&5]. These families are closely related to
Malvaceae s.s. but they are not monophyletic groups as shown by
numerous researchers on the Malvales e.g.[6- 8] . The nine subfamilies:
1. Bombacoideae, traditionally in family Bombacaceae
2. Brownlowioideae, traditionally in family Tiliaceae
3. Byttnerioideae, traditionally in family Sterculiaceae
4. Dombeyoideae, traditionally in family Sterculiaceae
5. Grewioideae, traditionally in family Tiliaceae
6. Helicteroideae, traditionally in families Sterculiaceae (tribe
Helictereae) and Bombacaceae (tribe
Durioneae)
7. Malvoideae, traditionally family Malvaceae s.s.
8. Sterculioideae, traditionally in family Sterculiaceae
9. Tilioideae, traditionally in family Tiliaceae

Dear friends
As Understood now, the family Malvaceae (according to APG III) includes genera formerly included under Malvaceae, Tiliaceae, Sterculiaceae and Bombacaceae. So please also include the genera of these former families under Malvaceae Week. Here is the complete list of genera (total 236):
