Boris after some work on Sunday

Just started working on the flowers. I hate painting yellow flowers!

Can we see any difference? Sometimes I wonder where all the time goes... I can hardly see any difference, but it is there. Promise.

Back from Bali and Java

So I am back from Indonesia and had a great time. The wedding was really beautiful and fascinating. I managed to get some sketchbook work completed, which is good, but I wanted to do more. There was so much beauty to capture, and I seemed to take quite a while in getting each painting completed!

Me painting... again...

Painting a leaf in Sidemen

I will upload the sketchbook work tomorrow... But for now here are some other shots..

Borobudur, Java - Marianne North has also been here.

Marianne North's painting

I have to say - I didn't know at the time, but when I was on top of the temple I thought to myself 'I bet she's been here' - it just felt like her kind of place and when I got to work today, I went straight to the guide book to see... It feels really magical to have been where Marianne has been. Wonderful stuff indeed.

Borobudur, Java

More painting...

The wedding... yes, it rained. These are the dancers they had - they were fabulous.

Mr and Mrs. Jessie - sorry for the confusion on which Jessie was getting married this month!
Me very happy relaxing in Ubud...
Chinese New Years Day, Jakarta - you have never seen so much insense in your life and yes, that is a human-sized candle.

Off to Bali... for Jessie's And Jessy's wedding!

Have a great 3 weeks everyone. I guess now you can all see why I have been rampaging in my studio to get ahead of the 'game'...

Notes on dissections for you all

I regard myself as lucky on this course, because I have done a year's worth of botanical taxonomy training... I kind of know what I am looking for when dissecting a flower. I know, for example that most flowers from the Rose family - Strawberry's, Roses, plums etc... have a hypanthium and I know the different types of arrangement in which the ovules can be arranged in an ovary. So before I go to Bali, I have loaded up some pictures from the best taxonomy book around with the hope that it will help all those who are doing dissections while I am away.

This is the book:

So we have all seen this type of diagram?


But there is so much more:

The diagram above shows you what it 'should' look like if there is a hypanthium present... The reason is starts as absent, then the hypanthuium appears and then goes absent again in the sequence is due to evolution... So you can end up with any of the 5 arrangements as shown above.

This shows how the gynoecium (female bit) can be arranged. The circles are transverse sections, the other longitudinal. As you can see, the ovules can be arranged in a number of ways in each locule (ovary). Along a column (axile), all around the edge (parietal), along one side of the edge (marginal) and sometimes several ovary's fuse to create a bigger septate ovary that has several cavities inside. Sometimes the axile placentation doesn't join at the top, and then it is called 'free central', and if there is only one ovule, then this can either be in the ovary as basal or apical depending on how it connects to the tissue.

This is how different anthers can empty themselves of pollen (dehiscence). Can be very important in dissections - especially in orchids.

Again, different dehiscence types on anthers.

Different arrangements of petals for a floral diagram

And - floral diagrams.. I find floral diagrams very easy to do and they can transform what is a very difficult flower to draw into a very easy one. This is for Julie so she understands what I was talking about on the cyclamen on the last comments in that post.

If you are donig a longitudinal section, you need to imagine what would be cut through the middle and what wouldn't be if you draw a line from the axis symbol all the way down the middle of that picture above to the bottom. When cutting a flower in two, you rarely get it straight down the middle, so you need this to refer to, plus the real flower in front of your to cross refernce with. I hope this helps.

A bit more completed on Polly...

The dissections have been a REAL pain to do. I didn't realise that the flower was a double to begin with, plus there is a hypanthium to remember and all the sexual parts are leafy, so nothing is normal - no anthers, no 'filaments' and no ovaries! Anyway, I am very satisfied with the piece and luckily my friend Alex's herbarium specimen and fresh plant arrived in time, along with a pickled fruit which I have received from another Alex, it makes me very well sorted - (I began this painting with no material - everything from memory!

Sketchbook bits...

Tonight I will be doing a bit of work on Polly, but in the meantime I thought I'd post some bits from my sketchbook. None of the pieces correspond to any of the assignments at the moment, as these sketches are things I have done for fun over the past year. My sketchbook is in a ring bound file to keep everything together, along with 2 A4 notebooks.

A pea pod and colours for Sally

Study for Aiden the Aesculus which never got painted. Romilly replaced him.

A Rose study from my roses on Valentines Day 2011

Runner Beans from the garden study - not finished

Berberis dissection

Silene dissection and floral diagram

Orchid anatomy (Cymbidium)

Cyclamen anatomy, floral diagram and dissection. this was done a while back, but I thought it would be useful for Julie. But it may be wrong - can't remember - don't take my word for it! Maybe use it as a guide?
