I was recently in New Plymouth, where I took the opportunity to visit Pukekura Park. Aside from its lovely cricket ground, the Park is of course notable for its plants. Pukekura Park website. One of the botanical highlights for me was king fern, probably best seen at the Park inRead more

Tramping in New Zealand forests can be an enjoyable and very relaxing activity. However, if your legs are hairy, it could be a painful and very annoying experience. Camouflaged among ferns and ground orchids, hook grasses are waiting, ready to clasp to the hairs or clothing of any unwary tramper.Read more

I’m just back from the John Child Bryophyte Workshop for 2009, which I helped organise (along with Massey University’s Lara Shepherd and Jill Rapson). The Bryophyte Workshop studies mosses, liverworts, and hornworts, as well as lichens. Although often overlooked because of their small size, these plants are significant biodiversity andRead more

There’s ferns even in the desert. Strictly speaking, it’s apparently an “arid” region, rather than desert. In any case, it was dry.Read more

No, it is not Christmas already. (Fortunately the year hasn’t passed by that quickly.) But this pohutukawa on Wellington’s waterfront, opposite Frank Kitts Park, seems to think so. It has been spluttering into flower over the last few weeks. The pohutukawa (Metrosideros excelsa) is New Zealand’s ‘Christmas tree’, its burstingRead more

Joan Wiffen, who found hard evidence that dinosaurs had inhabited New Zealand, died this month aged 87. I’m not a scientist, but I do have an interest in the history of science, and even I can see that Wiffen made historically significant and far-reaching contributions to scientific thinking.   First findings In 1975, WiffenRead more

Aside from ferns, my main research interest is the group of trees known as Pseudopanax, for which I collaborate with Lara Shepherd from the Allan Wilson Centre. Pseudopanax includes the lancewoods and five-fingers. Several of the species are popular in cultivation, including fierce lancewood (Pseudopanax ferox). This species is soRead more

New Zealand’s plants have a bit of a reputation for pronounced promiscuity. There is supposedly a high rate of hybridisation, or individuals of one species breeding with individuals of a different species. I’m not entirely sure that this reputation is nationally deserved. Nevertheless, a striking example of hybridisation occurs inRead more

An infestation of a giant horsetail, Equisetum hyemale, has been found near Levin. It was spotted by eagle-eyed Department of Conservation staff. They gave us a specimen for Te Papa’s herbarium collection of dried plants.   No horsetail species occur naturally in New Zealand, but several have been purposefully orRead more

One of my previous posts discussed a recent study on New Zealand’s only endemic spider regarded as dangerous to people, the katipo. I thought readers might be interested to learn a little more about what’s behind the bad reputation of katipo and its’ close relatives. As I said then, katipoRead more

Most hen & chickens ferns in cultivation are the false hen & chickens fern, Asplenium ×lucrosum, rather than Asplenium bulbiferum.  The two are easily distinguished. Asplenium ×lucrosum is a sterile hybrid between Asplenium bulbiferum and Asplenium dimorphum.  The “×” preceding “lucrosum” indicates it is a hybrid. The two parent speciesRead more
