Re: Chamaecyparis nootkatensis 'Pendula'

Those are just beautiful! Are the ones called Green Arrow?

 

Re: Chamaecyparis nootkatensis 'Pendula'

Species now Cupressus nootkatensis, syn. Callitropsis nootkatensis, Xanthocyparis nootkatensis.

 

Re: Chamaecyparis nootkatensis 'Pendula'

Hi Karalyn, all photos are different clones but all are still referred to as 'Pendula'.

Re: Chamaecyparis nootkatensis 'Pendula'

So are we suppose to start calling Chamaecyparis nootkatensis 'Cupressus'?

 

Re: Chamaecyparis nootkatensis 'Pendula'

Cupressus = Cypress. Michael's comments relate to a voting which will occur in the next 8-10 years where all the conifer bigtimers will decide upon a new name for the Genus. Chamaecyparis being 'recognized' by the consumer and nurserymen presently which will change to : Callitropsis or Xanthocypress or Cupressus when this vote takes place as Michael has shown above.

Re: Chamaecyparis nootkatensis 'Pendula'

Just for this species - the other species of Chamaecyparis stay the same!

 

Re: Chamaecyparis nootkatensis 'Pendula'

Seems strange to start using new naming pre-vote by 8-10 years.

 

Re: Chamaecyparis nootkatensis 'Pendula'

The vote at the next botanical congress is to decide whether the newer name Xanthocyparis should be given priority over the older (but largely long-forgotten) name Callitropsis, if/when Nootka Cypress (and Vietnamese Cypress and ± some other cypresses) are treated in a genus of their own. This is a question of nomenclature.

Separate from this, is the taxonomic question of whether Nootka Cypress and Vietnamese Cypress etc., should, or should not, be placed in the genus Cupressus, or a genus of their own; this depends on genetic research. This is still uncertain; there is some evidence, but not conclusive, that some cypresses are more closely related to junipers than they are to other cypresses; if yes, then the genus Cupressus has to be split in two, if no, then it doesn't.

This latter does however have some bearing on the likely outcome of the vote, as one botanist who has recently completed a monograph on the cypresses has concluded that all of the American Cupressus species (including Nootka Cypress, and also Vietnamese Cypress) are genetically distinct from the European Cupressus species and should be treated in a distinct genus. The important factor regarding the future vote here is that in doing so, he used the name Callitropsis for the separate genus, which in his study comprises 18 species. But only two of them (Nootka Cypress and Vietnamese Cypress) have been given names in Xanthocyparis. If Xanthocyparis were to be voted the official name for this genus, it would mean that the 16 of these 18 species not given a Xanthocyparis name would have to be re-named yet again. It is unlikely that the members of the voting committee would favour this, so the vote is likely to support retention of Callitropsis as the new genus name.

Does this help clarify, or muddy the waters further?? ;-)

 

Re: Chamaecyparis nootkatensis 'Pendula'

Makes a lot of sense to me.

Here's a table Michael wrote a while back (note: italic characters not shown)

INFORMATION – (Michael F) 2007:

Chamaecyparis. Asia, North America; cones mature in 6-8 months.
Chamaecyparis formosensis - Formosan Cypress
Chamaecyparis lawsoniana - Lawson's Cypress
Chamaecyparis obtusa - Hinoki Cypress
Chamaecyparis pisifera - Sawara Cypress
Chamaecyparis taiwanensis - Taiwan Cypress
Chamaecyparis thyoides - White Cypress
Callitropsis - may be better regarded as a synonym of Cupressus, at least for the time being pending further DNA tests. North America, one in Vietnam; cones mature in 18-25 months (selected examples only):
Cupressus arizonica (syn. Callitropsis arizonica) - Arizona Cypress
Cupressus bakeri (syn. Callitropsis bakeri) - Modoc Cypress
Cupressus glabra (syn. Callitropsis glabra) - Smooth Arizona Cypress
Cupressus lusitanica (syn. Callitropsis lusitanica) - Mexican Cypress
Cupressus macnabiana (syn. Callitropsis macnabiana) - MacNab Cypress
Cupressus macrocarpa (syn. Callitropsis macrocarpa) - Monterey Cypress
Cupressus nootkatensis (syn. Callitropsis nootkatensis) - Nootka Cypress
Cupressus sargentii (syn. Callitropsis sargentii) - Sargent's Cypress
Cupressus vietnamensis (syn. Callitropsis vietnamensis) - Vietnamese Cypress
Cupressus, in the restricted sense. Eurasia, North Africa; cones mature in 18-20 months (selected examples only):
Cupressus atlantica - Moroccan Cypress
Cupressus cashmeriana - Bhutan Cypress
Cupressus dupreziana - Saharan Cypress
Cupressus funebris - Chinese Cypress
Cupressus sempervirens - Mediterranean Cypress

Re: Chamaecyparis nootkatensis 'Pendula'

Never mind mud, I feel like I'm sinking in quicksand!

Nevertheless, that list will be handy, thanks Dax, and of course Michael.

 

Re: Chamaecyparis nootkatensis 'Pendula'

You just need to grab onto some Nootka Cypress roots to pull yourself out by!

 

Re: Chamaecyparis nootkatensis 'Pendula'

... thus taking refuge in common names to protect oneself from the botanists! No wonder common names persevere :-)

 

Re: Chamaecyparis nootkatensis 'Pendula'

Name 10 people? Go!

 

Re: Chamaecyparis nootkatensis 'Pendula'

Yeah, but then someone comes along and tries to shoehorn it into Cedrus . . .

 

Re: Chamaecyparis nootkatensis 'Pendula'

OK, now pretend three of the women got married and changed their names, and one decided he didn't like the name his parents gave him so changed it, another one had a sex change, and two use nicknames. NOW recite them!

Good analogy, though; I've used it myself. And you're quite right that once you know the plants, remembering the new name isn't that hard. I do think it makes it harder for a newcomer to get to know them.

 

Re: Chamaecyparis nootkatensis 'Pendula'

Yessiree Bob! What makes it even harder is that I'm reading the names but I haven't heard them in person. I could be saying the whole name wrong. I really do like the simple names. But probably because they are in English and not in Latin or Italian or whatever. LOL

Yes, I agree quicksand definitely gives a super picture of how things can get more complicated.

 

Re: Chamaecyparis nootkatensis 'Pendula'

Men!
