摘要

摘要/ Abstract摘要:外型石竹(Tylecodon ectypus)是原产于Steinkopf以西skaapriviersport上游(Namaqualand北部)的一个新种。它是由它的地球植物的生长形式，圆形有光泽的叶片，厚的网状脉，烛台状的花序和喇叭状的粉红色条纹白色花冠来区分的。易危状态(世界自然保护联盟红色名录标准)是合理的，因为它的分布有限且分散，特别是考虑到它在三个已知种群中的两个种群中稀缺。

Tylecodon ectypus, a New Cliff Dwelling Species from the Skaaprivier, Northern Namaqualand (Northern Cape Province), South Africa

Abstract: Tylecodon ectypus (Crassulaceae) is a new species originating from the upper reaches of the Skaaprivierspoort, west of Steinkopf (northern Namaqualand). It is at once distinguished by its geophytic growth form, orbicular glossy leaves bearing thick reticulated veins, candelabriform inflorescences and trumpet-shaped pink-striped white corolla. Vulnerable status (IUCN red list criteria) is justified by its restricted and fragmented distribution, especially considering its scarcity in two of the three known populations.
