Dear Nhu, what an increase in the Massonia Wiki! Gottfried informed me, that you included Massonia sempervirens on the Massonia Wiki page. May I note, that you got something wrong as to M. pustulata Jacq. with your many additional photos. Jacq. was born in Leyden, hence the Dutch form Nicolaas of his Christian name in Brummitt & Powell, Authors of Plant Names (1992) and probably in IPNI, which is temporarily unavailable. In his publications he used the Latin form of his first given name: Nicolaus Joseph. The only true M. pustulata Jacq. among the 13 M. pustulata photos of the Massonia Wiki is Cameron's plant from Napier. All the 12 other M. pustulata photos are M. longipes, as proposed for Cameron's last photo from Agulhas (or are something else, without a locality safe identifications are hardly possible). Are your last three photos all from the Overberg region or the southern Cape or are Massonia pustulata 'Loeriesfontein' among them? Do you have the paper by Wolfgang Wetschnig et al. STAPFIA 97 (2012):210--221 at hand? Best wishes for the progres of your Diss. Dietrich
