Agalmyla Blume (including Dichrotrichum de Vriese and Tetradema Schltr.) (Gesneriaceae-Cyrtandroideae) is revised. Ninety-seven species are recognized, 62 of them newly described, and these are divided into three sections with distinct geographical ranges. Sect. Agalmyla (24 species) is restricted to the Malay Peninsula, Sumatra, Java, Borneo and Palawan; sect. Exannularia (19 species) is the only section on Sulawesi and has a few species nearby; sect. Dichrotrichum (54 species) is represented in the Philippine Islands (excluding Palawan) by 13 species, in the Moluccas by two species, and in New Guinea by 39 species. No species is found in more than one of these areas and the key to sect. Dichrotrichum is therefore split between the Philippine species and those on the Moluccas and New Guinea. There are thus four keys altogether. The affinity and geographical distribution, both of the whole genus and of the sections, are discussed, and special attention is given to distribution of species in relation to the geological terranes of New Guinea. Points of interest and taxonomic importance in the morphological features are noted in a separate section.

Cyrtandra sect. Dissimiles C. B. Cl., sect. Radicicaules Kraenzlin and sect. Radiciflorae Kraenzlin are lectotypified. Two varieties are raised to specific rank: C. dispar var. glabriflora B. C. Stone to C. stonei (Malay Peninsula), C. decurrens var. polyneura C. B. Cl. to C. polyneura (Sulawesi). Nineteen new species are described (11 from Sarawak, 1 from Sarawak and Kalimantan, 7 from Sabah—6 of them from Mt Kinabalu). Annotations are provided on 6 previously known species: C. calycina Benth. (New Guinea), C. debilis Kraenzlin (Kalimantan), C. farinosa C. B. Cl. (Sarawak), C. ligulifera C. B. Cl. (New Guinea), C. rubropicta Kraenzlin (Kalimantan and Sarawak), and C. russa C. B. Cl. (Sarawak).

Abstract A description is provided for Acroconidiella tropaeoli. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Tropaeolum spp. DISEASE: Causes severe losses in nasturtium seed fields in coastal California. It produces a yellowing and death of the leaves after mid season and this reduces yield. The fungus occurs sometimes on stems and is present on seeds but is most abundant on leaves where it forms characteristic irregular or subcircular brownish or purple spots visible on both sides. These are up to 1 cm diam. or often larger through confluence, the centres later shrivel and the surrounding tissues may form a broad yellow margin. GEOGRAPHICAL DISTRIBUTION: Argentina, Australia, Ceylon, Ethiopia, Guatemala, Haiti, India, Jamaica, Kenya, Mauritius, New Guinea, New Zealand, Tanzania, Uganda, U.S.A. TRANSMISSION: The pathogen is borne internally and externally in up to 93% of commercial nasturtium 'seed', persisting for at least 3 years in the form of thick-walled mycelium in the pericarp and seed.

Abstract A description is provided for Puccinia cynodontis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Aecial stage on species of Plantago. Uredial and telial stages on species of Cynodon, particularly C. dactylon. DISEASE: Leaf rust of Bermuda grass (Cynodon dactylon). GEOGRAPHICAL DISTRIBUTION: Widespread. Africa: Ethiopia, Ghana, Kenya, Libya, Malawi, Mauritius Morocco, Nigeria, Sierra Leone, South Africa, Sudan, Tunisia and Zambia. Americas: Argentina, Barbados, Bermuda, Colombia, Dominica, Dominican Republic, Jamaica, Mexico, Nicaragua, Panama, Puerto Rieo, Salvador, Trinidad, USA (South) and Venezuela. Asia: Cambodia, Ceylon, China, India, Iraq, Pakistan, Turkey and USSR. Australasia & Oceania: Australia, Hawaii, New Caledonia, New Zealand and Papua & New Guinea. Europe: Cyprus, France, Malta and Rumania. TRANSMISSION: No studies appear to have been reported. Since the aecial stage has not been found in USA the urediospores presumably survive during the dormant periods of the tdial host.
