Did you know that Hook Grasses can control water loss by folding up their leaves? Contrary to their common name,  Hook Grasses are not grasses but Sedges and they belong to the family Cyperaceae.  Sedges are commonly found in wet or poorly drained habitats. Hook Grasses, however, can be found in a much greater diversity of habitats.Read more

PLEASE NOTE THAT THE FOLLOWING IMAGES MAY BE DISTURBING The dissection of the killer whale finished yesterday.  This killer whale was very young when it stranded and died.  It was given to Te Papa by Te Runanga o Makaawhio and measured just over two metres long. Its tongue had flaps likeRead more

I was out last week with Tim Park from the regional council looking for Pseudopanax hybrids between lancewood and coastal five-finger near Porirua. Coastal five-finger and the hybrids are weeds in the Wellington region. Previous post on lancewood and coastal five-finger hybridisation. We spotted a couple of other weedy nativesRead more

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

There were killer whales (orca) hanging around Wellington harbour yesterday – as reported by Anton van Helden, Te Papa’s marine mammal specialist. More killer whales were seen this morning, though I’d don’t know if they are  the same animals. After a txt from Anton I raced down to the SouthRead 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, Wiffen found somethingRead 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
