TL;DR: The styloids form a synapomorphy for a monophyletic part of the Claoxylinae (Claoxylon, Discoclaoxylon), which supports a clade in a recent molecular phylogenetic study that unites subtribes Claoxyinae and Lobaniliinae as Claoxyllinae s.l.
TL;DR: Discoclaoxylon pubescens (Pax & K. Hoff m.) Exell, endemic to Annob o n Island (Equatorial Guinea), is here lectotypifi ed from Mildbraeds original material found in the Herbarium Biozentrum Klein-Flottbek of Hamburg (HBG).
Abstract: Discoclaoxylon pubescens (Pax & K. Hoff m.) Exell, endemic to Annob o n Island (Equatorial Guinea), is here lectotypifi ed from Mildbraeds original material found in the Herbarium Biozentrum Klein-Flottbek of Hamburg (HBG). A detailed morphological description of the female characters (fl ower and fruit), before unknown, is provided, completing the earlier recollections with fruit material. A comparison of the main characters of the other three species of the African genus, along with a key, is provided. A drawing of D. pubescens , never illustrated before, and photographs of fl owers, fruit and seed, are provided. Discoclaoxylon Pax & K. Hoff m. is an endemic African genus comprising four species, three from the islands in the Gulf of Guinea ( D. occidentale Pax & K. Hoff m. (S a o Tom e ), D. pedicellare Pax & K. Hoff m. (Bioko) and D. pubescens (Pax & K. Hoff m.) Exell (Annob o n)), the other extending
