This revised synopsis of the taxa of Euphorbiaceae recognizes, and provides keys to, 5 subfamilies, 49 tribes, and 317 genera. Two new tribes, Croizatieae and Podocalyceae, are proposed, as well as four new subtribes, Leptopinae, Podocalycinae, Pycnocominae, and Tetracoccinae; five taxa are reduced to subtribal status. One genus (Ophellantha) is reduced to a section; 14 new binomial combinations are proposed. Lectotypifications are provided for almost all taxa not previously typified 
FIVE RARE GENERA OF EUPHORBIACEAE (SENSU LATO) IN THE MALAY ARCHIPELAGO: ALPHANDIA , ASHTONIA , BORNEODENDRON , CLADOGYNOS AND TAPOÏDES
TLDR
The females of five relatively unknown Euphorbiaceous genera are redescribed and Ashtonia (two species) is presently classified in the Phyllanthaceae.
Revision of the genus Leptopus (Phyllanthaceae, Euphorbiaceae sensu lato)
TLDR
Revision of the Asian genus Leptopus (Phyllanthaceae tribe Poranthereae) is presented recognising nine species and eight new synonyms are made and ten lectotypes are chosen.
A REVISION OF TRIADICA LOUR. (EUPHORBIACEAE)
TLDR
A revision of the Asian genus Triadica is presented, with three species accepted, T. cochinchinensis, sebifera, and T. rotundifolia, with one new synonym included and a note on the validity of the name Croton macrocarpus.
A NEW COMBINATION IN CROIZATIA (EUPHORBIACEAE)
TLDR
The unispecific genus Pseudosagotia is placed in synonymy under Croizatia and a new combination, Croiz atia brevipetiolata (Secco) Dorr, is proposed for its sole species, a dioecious species that was known previously only from female flowers and fruits.
A revision of the Malesian genus Blumeodendron (Euphorbiaceae)
TLDR
Two important characters were newly discovered, the presence of small lepidote hairs in all species and the indehiscent fruit of B. endocarpum.
Revision of the genus Cleidion (Euphorbiaceae) in Malesia
A revision of the Malesian species in the genus Cleidion is presented. Cleidion javanicum is shown to be the correct name for the widespread type species (instead of the name C. spiciflorum). A new
Synopsis of Euphorbia (Euphorbiaceae) in the state of São Paulo, Brazil
Euphorbia is the largest genus of Euphorbiaceae and is among the giant genera of Angiosperms. In the state of Sao Paulo, the genus is represented by 23 species occurring in savannas, high altitude
Rhodothyrsus, a new genus of Euphorbiaceae from tropical South America
The new genusRhodothyrsus is proposed, based on the AmazonianSenefeldera macrophylla Ducke but also containing another newly described species,Rhodothyrsus hirsutus from northwestern Venezuela. The
New records of three species and a genus of the Euphorbiaceae for Bangladesh
Three species belonging to two genera of the family Euphorbiaceae are beingreported here as new records for Bangladesh, viz., Cleidiocarpon laurinum Airy Shaw, Euphorbia pycnostegia Boiss. and
A taxonomic revision of Mallotus section Polyadenii (Euphorbiaceae).
TLDR
The identification of species is difficult, especially of M. leucodermis and M. muticus, which are partly sympatric and only pistillate flowers or fruits provide reliable characters; specimens with staminate flowers are very difficult to identify.
