The wood anatomy of Gardenieae, Ixoreae and Mussaendeae (Rubiaceae)

Koek-Noorman, Jifke (1972)
The tribe Gardenieae in the restricted delimitation proposed by Bremekamp and Verdcourt is wood anatomically homogeneous. The genera of the Ixoreae studied by me also agree with each other in wood structure. Within the tribe Mussaendeae in the delimitation accepted by Schumann the wood anatomy shows much variation. The tribe becomes more homogeneous, if some of the genera included in this tribe by Schumann are removed. The systematic position of some genera, which in the literature are said t...

Depositional history and clay minerals of the Upper Cretaceous basin in the South-Central Pyrenees, Spain

Nagtegaal, P.J.C. (1972)
An ordered sequence of well-defined sedimentary environments reflects the deepening and shallowing stages in the depositional history of the Upper Cretaceous basin in the South-Central Pyrenees, Spain. The sequence, which has a Santonian age at its base, starts with a calcarenite barrier system on which occurs a coral reef showing well-differentiated fore- and back-reef facies (Congost Limestone Formation). Marked deepening of the basin occurred during the deposition of the overlying glauconi...

Amplitude Modulation of an Acoustic Wave Propagating Near the Sea Surface

Smith, W.J. (1972)
Approved for public release; distribution unlimited. Sixty Khz CW sound was propagated parallel to and near the ocean surface adjacent to an array of four thermistors, a salinometer, a sound velocimeter, a turbulent velocity probe, and a wave-height probe in order to investigate the statistics and environmental causes of amplitude modulation. The temporal variations of the sound amplitude modulation were studied during four twenty-minute runs over a range of 2 meters at varying depths fro...

Bryum gemmiparum De Not. nieuw voor Nederland

Gradstein, S.R.; Melick, van, H. (1972)
First record of Bryum gemmiparum de Not. from The Netherlands. The taxonomy and distribution of the species are discussed. Bryum gemmiparum was collected in a clay-pit along the river Maas in the north of the province of Limburg. This locality seems to be the northernmost one known of the species. Bryum gemmiparum was found growing on steep, rather humid, loamy soils in a luxuriant cover of bryophytes characterized by Anisothecium varium, Riccardia sinuata, Riccardia pinguis, Bryum bicolor, D...
