A revision of certain generic boundaries within the tribe Malveae is made. A new genus,Sidasodes, is described with two species, one of which is new,Sidasodes colombiana.Akrosida is segregated as a new genus, based onBastardia macrophylla. The new realignment also recognizesTetrasida as a distinct genus, and describes as newTetrasida serrulata. New combinations includeSidasodes jamesonii (based onSida jamesonii),Akrosida macrophylla (based onBastardia macrophylla), andTetrasida chachapoyensis…

Akrosida floribunda (Malvaceae), a new arborescent mallow from the Dominican Republic

A new species,Akrosida floribunda, is described from the Dominican Republic. This arborescent genus is now known from two species, the other beingAkrosida macrophylla, from Brazil. Both have very

Callianthe (Malvaceae): A New Genus of Neotropical Malveae

Not only is Callianthe phylogenetically removed from both Bakeridesia and Abutilon, but it is also morphologically distinct from its closest phylogenetic relative, Gaya, which has a base chromosome number of x = 6.

The American genera of Malvaceae—II

The genera of Malvaceae that occur in North, Central, and South America (including the Caribbean) are enumerated, described, and distinguished, using an artificial key. The usual taxonomic

Fruits and Pollen of Malvoideae (Malvaceae) in the Maastrichtian–Danian Deccan Intertrappean Beds of Central India

Malvaceae were an important component of vegetation represented in the Deccan Intertrappean beds in central India, as verified by fruits and pollen. We review the extinct schizocarpic fruit genera

A new genus from Mexico: Dendrosida (Malvaceae)

An analysis of mericarp morphology in relation to seed dissemination mechanisms indicates that the Abutilon alliance may be divided into an Abutiloid and a Sidoid group, and Dendrosida is included in the latter.

Neotropical Segregates from Sida L. (Malvaceae)

Mericarp and calyx morphology are emphasized in delimiting these genera and in defining the residual genus Sida, which now assumes a more natural character.

Revision of the genus Anoda (Malvaceae)

A revision of the genus Anoda is presented that recognizes 23 species, of which ten are described as new, and the two genera together seem to occupy a relatively isolated position within the family.

The genus hampea(Malvaceae)

The genus Hampea Schlecht is included in the Malvaceae, tribe Gossypieae, rather than in the Bombacaceae where it was originally placed, and the following taxa are described as new.

The American Genera of Malvaceae

The family Malvaceae offers many problems to the taxonomists. Opinions differ widely as to where to draw the line between species, between genera, antd between tribes. Even definition of the family

CHROMOSOME NUMBERS IN THE MALVALES. II. NEW OR OTHERWISE NOTEWORTHY COUNTS RELEVANT TO CLASSIFICATION IN THE MALVACEAE, TRIBE MALVEAE

The data support the thesis that the base chromosome number of the Malveae, or at least of the Abutilon alliance, is x = 8; that the genera of the New Zealand and Australian Plagianthus alliance were probably derived from abutiloid ancestors; and that the Chilean Malacothamnus chilensis (Gay) Krapov.

Blue flower pigmentation and evolutionary advancement

It is shown that environmental pressures were indeed the only, or even the dominating factors, a trend towards the representation in all families of all colourations should be noticeable, but this is not the case.
