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
Are you growing a hen & chickens fern at home? If so, chances are it’s a fake, unless you dug it out of the bush.Read 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
Black nightshade has been in the news recently, after its berries turned up masquerading as peas in packs of frozen vegetables.Read more
A three-metre giant squid specimen washed up on a beach on Wellington’s South Coast yesterday (2nd April).Read more
This amazingly comprehensive compilation of archival material relating to William Colenso’s botanical collections has just been published by the New Zealand Native Orchid Group. The material has been researched by Ian St George and includes unpublished work by the late Bruce Hamlin (former Curator of Botany at the National MuseumRead more
Chris Horne of the Wellington Botanical Society recently sent me a fern frond they collected on one of their trips. Although the frond is small and lacking the diagnostic reproductive characters, I think it is the introduced holly fern (Cyrtomium falcatum). It looks like the shining spleenwort (Asplenium oblongifolium), but theRead more
Breaking news from our squid fix-it team – the work is complete and we are on track to reopen the colossal squid exhibition to the public from tomorrow 21 March 2009. Yesterday Robert Clendon our Conservator and Hutch Wilco, one of our exhibition preparators finished the last few tweaks to theRead more
The rare, tetraploid maidenhair spleenwort (Asplenium trichomanes subsp. quadrivalens) has only recently been rediscovered in New Zealand. Several people have contacted me with possible additional sightings. As described by the Scoop website, Jack Ritchie had a maidenhair spleenwort self-sow on a rock used to construct a water feature in hisRead more
More news from the squid tank. This morning I caught up with Robert Clendon the conservator who is looking after the work on the squid. Over the past few weeks we’ve been a bit concerned about the hooks on the tentacles and the arms. It looked as though the hooks could beRead more
