FAMILY OF THE WEEK : MALVACEAE – indiantreepix | Google Groups
FAMILY OF THE WEEK: TILIACEAE – indiantreepix | Google Groups
Malvaceae Week: 05.09.11 to 11.09.11: Malvaceae Also called as Mallow family is a dicotyledonous family comprising about 82 genera and 1500 species, distributed almost throughout the world and particularly abundant in tropics.
In India, this family is represented by 25 genera and about 110 species. These include Annual or perennial herbs to shrubs or small trees.
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, Malvaviscus, Sida, Urena, Abelmoschus, Sidastrum,Herissantia, Wissadula, Modiola, Anoda, Decaschistia, Nayariophyton, Fioria, Senra, Lavatera, Althaea and Malachra
Hibiscus and pavonia are large sp represented by about 300 sp and 200 sp worldwide
Some important Plant include Gossypium sp (Cotton yielding), Abelmoschus esculentus (Vegetable) Thespesia populnea (Avenue Tree), Hibiscus sp, Alcea rosea (Ornamental) etc.

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

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): The Plant List
