| The aim of this book is to provide all persons interested in the tree and wood species of Suriname with a simple means to find the name of a given tree. To this end two dichotomous keys have been drawn up with the help of punched cards prepared from studies of conserved material and field observations made by the authors. The first one makes use only of vegetative characters of leaves and twigs and a few saliant features of the bark, disregarding flower and fruit characters mostly used in floras. The second key is based on the anatomy of the wood as far as this can be observed with a good 10 X or sometimes 20 X magnifying hand-lens. In the “Inleiding” the terminology applied in each of the keys and in the descriptions is explained and elucidated by sketch... |

| Three new species of Salacia are described. Salacia bullata spec. nov., a liana, characterized by bullate leaves, was collected in Brazil, Territorio Amapa. It comes closest to S. amplectens. A.C. Smith’s key (1940) should be amended to include a new group ‘Amplectentes’. This group, containing S. bullata and S. amplectens would be near ‘Arboreae’. Salacia alwynii, spec. nov., a vining species comes from Peru, Maynas, and is characterized by very large leaves and large cauliflorous flowers. It belongs to the species group ‘Ellipticae’ sensu Smith. It was also collected in Venezuela. Salacia paradoxa spec. nov. is a liana collected in Brazil along the Manaus-Caracarai road. Its long leaves are narrowly elliptic, its flowers are extremely small. In leaf... |

| A description is given of two new species in the genus Pristimera, P. dariense from Panama and P. caudata from Suriname. P. dariense differs by its flattened disk from the other New World species of the genus, but would fit in the subgenus Trochantha N. Hallé known from Africa. Cuervea crenulata sp. nov. is a species collected in Brazil, Minas Gerais. Another species in Cuervea, C. mitchellae (Johnst.) A.C. Smith is considered as a synonym of C. kappleriana. Hylenaea unguiculata sp. nov. is a new species from Suriname. The material on which the new species is based was at first erronously ascribed to the genus Tontelea with remarkably similar flowers. |

| The Scrophulariaceae, though chiefly a family of herbaceous plants, contain also a number of genera with trees ( Paulownia and Wightia) and genera with species of suffruticose and fruticose habit. My colleague Mr. A. M. Cleef, who is studying the vegetation of the high Andean parts of Colombia collected material of the small genus Aragoa, endemic in the paramos of the Colombian and Venezuelan Andes. Though this genus consists in the main of small broomlike shrubs, a new species, Aragoa perez-arbelaeziana Romero, discovered by him, is a small tree, of which the stem reaches a diameter of 8 cm. The wood of Aragoa of which the structure was so far unknown, proved to be noteworthy because of the complete absence of rays and parenchyma. There was no indication... |
