Aliform-confluent xylem parenchyma discovered in the rubiaceous genusGleasonia strengthens its controversial alliance with the problematical generaHenriquezia andPlatycarpum. Retention of these three genera in the Rubiaceae is supported by the occurrence of two family characteristics among them: vestured pitting on the vessel elements of all and, inHenriquezia only, the ability to accumulate aluminum in the wood. 


Wood anatomical characters, especially the fibre type and axial parenchyma distribution, have indeed good taxonomic value in the Rubiaceae, but the application of wood anatomical data is more useful in confirming or negating already proposed relationships rather than postulating new affinities for problematic taxa.

Aluminium accumulation in Rubiaceae: An additional character for the delimitation of the subfamily Rubioideae?

Al accumulation is almost limited to the subfamily Rubioideae, however, not all tribes show the character, especially the predominantly herbaceous Anthospermeae, Paederieae, RubieAE, and Spermacoceae.

Comparative wood anatomy of species of Psychotria L. (Rubiaceae) in Atlantic Rainforest remnants of Rio de Janeiro State, Brazil.

The statistical analyses allowed the segregation of the species and indicated the importance of habit (arboreous or shrubby) on the wood anatomy of the Species and the wood characteristics are more related to the specificities of each studied taxon than to with environmental variations.

The wood anatomy is discussed in relation to taxonomy of studied species and the main anatomical differences were: presence of sheath cells and type of inorganic inclusions on rays; vessels frequency, width, and length; rays frequency, length, and width; and fibres length.



Wood anatomy and classification of Henriquezia Spruce, Platycarpum Humb. et Bonpl. and Gleasonia Standl

An attempt is made to construct a cladogram according to Hennig’s principles and the resulting arrangement of the taxa concerned is discussed and compared with earlier conclusions based on phenetic comparison.

Systematische Holzanatomie einiger Rubiaceen

The anatomy of the secondary xylem of the Rubiaceae confirms the relationship between genera and tribes as delimited and arranged by recent authors (Bremekamp, Verdcourt). Two character complexes can

On the position of Platycarpum Humb. et Bonpl., Henriquezia Spruce ex Bth. and Gleasonia Standl

The main object of this study is to ascertain as precisely as possible the taxonomical position of these three rather puzzling genera.

A Chemical Spot-Test for Aluminum and Its Value in Wood Identification

Analysis of ashed wood samples that react positively revealed a high concentration of aluminum and the use of this spot-test has already proven to be a very useful adjunct to the classical methods of wood identification.

“Timbers of the New World”

IN his review of Record and Hess's “Timbers of the New World”1 Mr. Alexander L. Howard devotes half of a long paragraph to a mild reproof of the authors for saying something which actually they never
