Perfect time to see Sorbus fruits

It is a perfect time to see Sorbus fruits.
http://www.botanicalgarden.ubc.ca/asian-garden UBC Botanical Garden website says that there are about 70 species and forms of Sorbus. They are so different in leaves shapes and in size and color of berries.

With white berries. 1.Sorbus koehneana,China2.Sorbus aff. microphylla 3.Sorbus setschwanensis,China 4.Sorbus foliolosa,Himalayas


With most familiar red berries. 1.Sorbus decora,Greenland, Canada 2.Sorbus sudetica, Europe 3.Sorbus hybrida cv. Gibbsii,Garden Origin 4.Sorbus americana,e Canada, USA


With yellow or orange berries. 1.Sorbus cv. Joseph Rock, near entrance 2.Sorbus aff. thibetica 3.Sorbus commixta,Korea,Japan,Far East 4.Sorbus yuana



With pink berries. 1.Sorbus macrantha,China 2.Sorbus pseudovilmorinii,China


With blue? berries. Sorbus aronioides, China

 

Nadia was the Sorbus specialist yesterday, but I have a few to add.

[Edited] I had this mis-labelled. The ID of this Christmas tree is Sorbus sargentiana SEH 152.


Sorbus caloneura is not colourful like the others, but the fruits have an interesting surface and shape and I liked the way they sit up on top of the branches.


And speaking of not colourful, Nadia refused to photograph this Sorbus intermedia because it didn't have any fruits. It has great leaves, though.

 

It's not Sorbus intermedia. Like other apomictic microspecies, that is highly consistent in leaf form and shape, and this photo doesn't match as it should.

 

I don't seem to have taken a habit photo. I've added to the original posting another leaf photo and the label. I understand you're saying that it's the garden that has got it wrong.

Are you able to say what looks wrong about it?

 

Yep, it's the garden that has got it wrong, not you! The lobe shape is wrong, the apical lobes too sharply pointed at the apex, and the basal lobes too deeply incised. It looks more like Sorbus mougeotii, but isn't right for that either. But there are dozens of other similar apomictic whitebeams to chose from; all ultimately derive from complex hybrids between Sorbus aucuparia and S. rupicola and/or S. torminalis.

Is the origin of the plant 039718-5669-2010 traceable?

I've got some pics of genuine S. intermedia and will post them when I can find them in my pics folder!

If UBC wants seed of genuine S. intermedia I can easily get some (it is very commonly planted around here).

 

This seems to be from a local wholesale grower.

 

That tag I removed in posting #2 really belongs to this narrow upright Sorbus sp. with broad, simple leaves behind the picnic tables near the plant centre (thanks to Douglas Justice for sorting that out for me and for supplying the words for the description).

 

Still perfect time to see Sorbus fruits

After reading the October newsletter from the UBCBG Wendy and me realized that we didn't finish our Sorbus exploring job and found all sp. mentioned in the article, what we didn't see and so couldn't post.
In Asian garden
Sorbus glabriuscula (Hubei mountain ash) with white berries(pomes),
Sorbus vilmorinii (Vilmorin's mountain ash) with pink berries
Sorbus hemsleyi, pretty big yellow berries look more like Crabapple fruits.

In North garden.
Sorbus reducta (dwarf mountain ash, 60 cm tall), very small cute trees with pink pomes, very hard to notice.
Another Sorbus poteriifolia is even smaller, it looks like ground cover, but leaves and berries so Sorbus that no doubt, it is Sorbus! But Flora of China says, it can be up to 2.7m. Can be much taller than Sorbus reducta!

 

Perfect time to see Sorbus fruits, new sp. not posted before.

More Sorbus sp. not posted before.
Sorbus pseudohupehensis, China
Sorbus multijuga, China
Sorbus cashmiriana, Kashmir
Sorbus karchungii, Pakistan?
Sorbus pallescens, China

 

With regard to the Sorbus x intermedia-labeled plants, I'd very much like to know what they are. I'm still working on the original source. We purchased plants (all uniform, so presumably apomictic) from a reputable local wholesaler who purchased the seed from a reputable American broker/grower. The trail probably does not end there, but my guess is that the seed is American.

Sorbus karchungii is a Bhutanese plant. See below (from Rushforth, in the IDS Yearbook, 2009)

Sorbus karchungii Rushforth sp. nov.
Species nova, Sorbi wardii affinis sed foliis oblonge ovatis ad suborbiculatis, duplicato-serratis partem superiorem versus, venis 11 - 18(- 22) paribus; e Sorbo thibetica fructibus moderate lenticellatis, luteo-aurantiacis differt.

Sorbus karchungii is close to Sorbus wardii but differs in its oblong-obovate to sub-orbicular leaves which are sharply doubly toothed in the upper half and the more numerous (11 - 18(- 22) pairs) leaf veins; from Sorbus thibetica in its moderately lenticellate, yellow-orange fruit.

Type: cultivated specimen from Rushforth 1776, grown from seed collected in Bhutan, Tashigang, from Radi Gompa on the way to Merak, crest of the Mindu la, 11,150 feet (E, holotype, collected October 2009).

 

It isn't one of the ones I'm familiar with, I think I have seen it or a very similar whitebeam occasionally, but as I mentioned, there are numerous options.

Just to repeat: if you'd like some genuine Swedish Whitebeam seeds for growing, I can easily collect some. But it'll have to be soon, as the birds will have eaten them all before long.

 

Here's some pics of Swedish Whitebeam from today:

#1: Typical row of trees in a public park - it was one of the most popular trees for civic planting about 40-50 years ago. Unfortunately it's been an early autumn (after a cold wet summer) here, so most of the leaves are shed already.

#2: Typical tree. Note the stout, single trunk (c.f. Sorbus mougeotii, which usually has slender multiple trunks).

#3: Foliage still green on the lower branches of a sheltered tree. Flat leaves (never wrinkled in the sinuses like the UBC specimen) broadest at middle, with even, rounded lobes; only thinly greenish-white hairy below.

#3: Caught the tail end of the fruit crop, though most was already gone! Consistently orange berries (not red as in most other whitebeams).

 

Re: Perfect time to see Sorbus fruits - Autumn whites

Sorbus with white fruits caught my eye today.

Here's one that was reported before, but different individuals, maybe - Sorbus Koehneana.


I thought the small Sorbus in the right foreground at the Meyer Glade would have been a renegade seedling of the the S. Koehneana in the left background, seeing as how it's growing from the stump of the red cedar (?), but it has its own tag: Sorbus sp. aff. glomerulata.



Another Sorbus Koehneana.


This is the Sorbus glabriuscula that you can see from the boardwalk to the garden entrance. It's been posted before. The second photo is from October 3.


Here is another S. glabriuscula.

This Sorbus pseudovilmorinii on the main path almost qualifies, as a lot of the pomes on it are white now, but there's still a lot of colour.

 

Re: Perfect time to see Sorbus fruits - a few not white

Here are a few more Sorbus, not white, but not that colourful either.

Well, this Sorbus aff. thibetica does have a nice orange colour to the fruits.


But Sorbus aronioides doesn't seem to have any colour you could name.


And same for this Sorbus keissleri. These pomes are a good size, though - some of them almost 2cm long.

 

Re: Perfect time to see Sorbus fruits, new sp. not posted before.

Daniel Mosquin featured the Sorbus pallescens from the garden in Botany Photo of the Day today. His photo shows berries with much more red colouring than in Nadia's photo, though you can see tinges of red in hers.

 

I have a photo similar to Nadia's -- it depended on whether you photographed the fruit from the side or from the same place as the sun. Where the fruit is directly in the sunlight, it will flush.
