Abstract

Background: Ongoing systematic studies in the African flora necessitate periodic nomenclatural adjustments and corrections.

Objectives: To effect requisite nomenclatural changes.

Method: Relevant literature was surveyed, and type material was located and examined.

Results: A new combination is published in Dimorphotheca Mairia Vaill. ex Moench (Asteraceae). Nomenclatural adjustments are provided for five recently described species of Hyacinthaceae in order to accommodate them in alternative classification systems currently in use.

Conclusions: The new combination Dimorphotheca pinnata var. brevis (Norl.) J.C.Manning is made for Osteospermum pinnatum var. breve Norl. Eliokarmos craibii Martínez-Azorín et al. and Nicipe rosulata Martínez-Azorín et al. are transferred to Ornithogalum as Ornithogalum craibii (Martínez-Azorín et al.) J.C.Manning and Ornithogalum rosulatum (Martínez-Azorín et al.) J.C.Manning, respectively; Stellarioides exigua Martínez-Azorín et al. and S. littoralis N.A.Crouch et al. are transferred to Albuca as Albuca exigua (Martínez-Azorín et al.) J.C.Manning and Albuca littoralis (N.A.Crouch et al.) J.C.Manning, respectively, and the genus Desertia Martínez-Azorín et al. is included in Massonia with the new combination Massonia luteovirens (Martínez-Azorín et al.) J.C.Manning.

1. A new combination in Dimorphotheca Vaill. ex Moench (Asteraceae: Calenduleae)

Introduction

The species Osteospermum pinnatum (Thunb.) Norl. (Asteraceae: Calenduleae) was transferred to Dimorphotheca Vaill. ex Moench by Nordenstam (2006:46) but the name O. pinnatum var. breve Norl. (Norlindh 1965), published after Norlindh’s (1943) revision of the genus, was overlooked and requires a combination in Dimorphotheca. This is provided here.

Taxonomic treatment

Introduction

Eliokarmos craibii Martínez-Azorín et al. (2015b), Nicipe rosulata Martínez-Azorín et al. (2014), Stellarioides exigua Martínez-Azorín et al. (2015a) and S. littoralis N.A.Crouch et al. (2014) are recently described species of Hyacinthaceae (alternatively treated as Asparagaceae subfamily Scilloideae) from southern Africa. They were named following the generic classification of subfamily Ornithogaloideae proposed by Martínez-Azorín et al. (2011), one of two classifications for the subfamily derived from substantively the same molecular phylogeny. This classification favours numerous small genera based primarily on floral characters. The alternative classification for Ornithogaloideae proposed by Manning et al. (2009) is a more conservative interpretation favouring larger, inclusive genera and is the preferred option among southern African botanists, where it has been adopted by the major herbaria in the country (e.g. BOL, NBG and PRE) and recent publications on the flora (e.g. Manning & Goldblatt 2012; Snijman 2013; Van Jaarsveld & Eggli 2016). Similarly, the recent recognition of the new genus Desertia Martínez-Azorín et al. (2015c) for two species of subfamily Hyacinthoideae tribe Massonieae closely allied to the genus Whiteheadia Harv. is incompatible with the classification adopted by Manning et al. (2004) in which this genus was included in an expanded circumscription of Massonia Thunb. ex Houtt. The combinations that are required to integrate these new taxa into the generic classifications proposed by Manning et al. (2004, 2009) are accordingly provided here (see also Manning & Goldblatt 2013).
