| São relatados resultados de três anos de estudos em ensaio de campo para verificar o uso consuntivo da água pela cana-de-açúcar em solo do tipo roxa-legítima. O ensaio foi instalado em talhão de cana da Estação Experimental de Ribeirão Preto. De 14 em 14 dias foram colhidas amostras de solo, entre fileiras de cana, às profundidades de 0-25, 25-50, 50-75 e 75-100 cm, e determinados, em estufa, os teores de umidade. Foram organizados gráficos para indicar as quantidades de água disponível, perdida ou evaporada, bem como para prever a ocorrência da fase crítica de necessidade de irrigação e estimar os períodos e quantidades de água a serem aplicadas. Tais gráficos mostram que, em geral, a irrigação seria necessária nos meses de julho a outubro, no local onde... |

| Os autores relatam observações sobre a transpiração de Spatkódea nilotica Seem (Bignoniaceae), pequena árvore africana aclimatada no Brasil e usada, no Estado de São Paulo, para arborização de ruas e como planta ornamental. A transpiração foi dterminada pelo método das pesagens rápidas, por meio de uma balança de torsão. Foram feitas observações sôbre o andamento diário da transpiração total da transpiração cuticular e do déficit de saturação dos folíolos usados nas determinações da transpiração total. Também foram feitas observações sôbre o movimento hidroativo dos estômatos. As comparações entre as curvas de andamento diário da transpiração total com as dos déficits de saturação dos folíolos usados mostram que as, duas restrições de transpiração,... |

| The material dealt with in this second part of "Octocorallia from the Malay Archipelago" comprises mainly specimens belonging to the family Nephtheidae. Most of these nephtheids were obtained during the cruise of the "Willebrord Snellius". In addition to this material I examined some specimens collected by the Siboga Expedition, which had to be identified or described again. Besides, there were in the Leiden Museum some unidentified colonies, obtained in Malayan waters. These, too, are now recorded. Several authors have already pointed out how difficult it is to identify Dendronephthya, owing to the unsatisfactory description by some previous authors, and because of the great number of variations within the same species. Suffice it to refer to the... |

| The somewhat peculiar genus Vahlia Thunb. (1782) was formerly regarded as an anomalous member of the Saxifragaceae, but in 1959 it was segregated as the monotypic family Vahliaceae by Dandy (in Hutchinson, Fam. Fl. Pl. ed. 2, 1: 461). The genus includes about three species, all of them highly variable in stature, flower size, and indumentum; this has resulted in the description of more than twenty “species”, whose names now appear in synonymy. This note, however, is chiefly concerned with the generic name, since it appears that Vahlia Thunb. is not correct under the Code and must be replaced by Bistella Adans. (1763). In the synonymy under the new combinations, all the relevant names so far traced are included, but it may well be that an experimental... |

| Flore générale de Belgique. Spermatophytes, vol. V, fascicule 1, par A. LAWALRÉE. Bruxelles, 1966, 108 p., 30 fig. Van deze flora, die ook voor de Nederlandse botanicus van groot belang is, verscheen onlangs de eerste aflevering van het 5e deel der Spermatophyten, evenals de vorige afleveringen — telkens 3 per deel — bewerkt door Dr. Lawalrée van de Rijksplantentuin te Brussel. Deze aflevering bevat de families der Tiliaceae, Malvaceae, Guttiferae, Elatinaceae, Cistaceae, Violaceae en Thymelaeaceae. Met de afsluiting van het 5e deel waaraan dus nu nog 2 afleveringen ontbreken zullen nu alle in België voorkomende families der Choripetalae zijn behandeld. Resteren dan nog de Sympetalae en de Monocotyledoneae. Wij spreken de hoop uit dat ook deze groepen door... |
