another look
 

Since my previous post, that growth or spike has gotten a wee bit bigger. I was still wondering what you guys think. Spike or new growth ?

Still hard to tell. Looks rather "spikey" but in time, you will know. Patience!

It is a bit early to judge.

I agree with Roberta, that it looks more like a bud than a new growth. But, we can't tell for certain till it is a couple of inches long.

However, it is also getting very late in the season for buds to appear, so from that perspective I would lean towards a new growth.

Out of curiosity, do you have a name for that Cym? It's really late for a spike for Cyms, but there are a few that bloom later...knowing its parentage would give a hint if it were one of those,

Spark Sprite
 

That is the name of this cultivar. It's supposedly a "heat tolerant" cym

Ah hah... It is Cym Sarah Jean x canaliculatum ... My Sarah Jean is in bloom now, canaliculatum blooms later, So a spike is very likely! Now you have to watch and wait. And with Cym canaliculaum as one parent, definitely "warmth tolerant" - in fact that one I grow in the greenhouse in winter so it only doesn't need cold, probably doesn't particularly like it,

Additional info
 

I had purchased this orchid last year from a nursery in Hawaii. The seller indicated that these orchids were kept outside year round and that the nigh time temps never got below 55 . I currently keep it indoors where the daytime temps these past few months are between the high 70's to the low 60's in the evening. I don't know if the following point is relevant or not but a previous growth as indicated on one of my earlier post turned out to be a new growth after all. It was growing relatively quickly but stopped all of a sudden. The growth in in a sort of a stasis. It's new leaves haven't unfurled yet so all I see these past couple of months is a slim pointy triangle. So as a side question why did the new growth suddenly stop and then all of a sudden it's putting out a new growth or spike ?

I meant that the daytime temps range from the high 70's to the high 60's with nighttime temps in the low 60's

Hard to know what is the trigger... but even without temperature variation, days are getting longer, the sun is getting higher. So the plant can "sense" the change. One of the parents - Cym caniliculatum - wont spike for another month or two, and that influence may be holding the spiking process back. This is the time to sit back and observe... This plant has a mixed parentage that may tug it in different directions. but a spike this late in the season is certainly possible, even quite likely,

I will venture that if you are keeping your plant inside, it is a growth on your plant, not a spike. If your plant has been inside, there is probably insufficient light to generate a spike given these parents. Just my thoughts on the question. Enjoy the surprise and wait and see what it turns out to be.

It's kept inside
 

By a very bright south window , also supplemented with grow lights. Since I posted the pic the growth has gotten marginally larger and has retained its bullet shape. It's also got dew drops on it, don't know though if it's indicative of anything or not.

So it's a waiting game
