@article {4051, title = {Molecular phylogeny of the genus Philodendron (Araceae): delimitation and infrageneric classification }, year = {2008}, abstract = {

The genus Philodendron (Araceae) is a large neotropical group whose classification remains unclear. Previous classifications are based on morphological characters, mainly from the inflorescence, flower and leaf shape. The classification by Krause, with few modifications, is still the most commonly used system. To examine phylogenetic relationships in the genus, two ribosomal DNA nuclear markers, internal transcribed spacer (ITS) and external transcribed spacer (ETS), and the chloroplast intron rpl16, were sequenced and analysed for more than 80 species of Philodendron and its close relative Homalomena. According to the resulting phylogeny, the genus Homalomena may be paraphyletic to the genus Philodendron. The inclusion of the American Homalomena species within the genus Philodendron might resolve this taxonomic problem. All three subgenera of Philodendron were revealed as monophyletic. Below the subgeneric level, the groups obtained in our phylogeny globally correspond to sections recognized in previous classifications. Among the morphological characters used by previous taxonomists to build their classifications, and which we optimized onto one of the most parsimonious trees, most characters were found to be homoplasious. However, leaf shape, characteristics of the sterile zone on the spadix and venation patterns are useful for delimiting subgenera and sections within the genus.

Homalomena vietnamensis from Vietnam is described as a species new to science and illustrated. It belongs to H. sect. Homalomena and differs from other species mainly by having leaf blades with a truncate to obtuse base, a non-constricted, rather thick spathe and a slender, subcylindric staminode in each female flower. A chromosome number of 2n = 38 was counted in root tip mitoses.

Summary. A comparative study of the leaf outline morphometrics of Monstera adansonii var. klotzschiana, M. adansonii var. laniata and M. praetermissa was carried out. The study focused on populations in isolated montane humid (brejo) forests of Cear\á state in Northeast Brazil and compared them with populations from Amazonia and the Brazilian Atlantic Forest. Digitised outlines were prepared from a total of 1,695 field-collected leaf images from 20 populations, and elliptic Fourier analysis was used to generate matrices of coefficients, from which six shape variables (principal components) were extracted using Principal Components Analysis. Intra-population variability and inter-population differences were analysed with multivariate distance methods. Separate analyses were carried out for each of three leaf size classes (juvenile, submature, mature) because of the strong heteroblasty typical of this genus. Juvenile leaves were the least variable size class within populations of M. adansonii var. klotzschiana. The shape variables expressed very similar types of variation in all three size classes. The Cear\á brejo populations of M. adansonii var. klotzschiana showed significant differences between mature leaf outlines in all pairwise comparisons; the Pacatuba population was the most distinct. The Cear\á populations did not cluster together exclusively. In all three size classes, populations clustered together into their taxonomic groups, most clearly so in mature leaves. No correlation between morphological and geographic distance matrices was found, nor between morphological and molecular distance. The study showed that leaf outline shape is a practicable and useful quantitative trait for studying morphological variability at species, varietal and population levels.
