C. C.G. Roebling surprise buds

I bought this plant on my June visit to Cal-Orchid.  It had previously bloomed on two leads but the newest, immature growth had no sheath.  I was surprised to see these two small buds that emerged despite the absence of a sheath.  One sees this occasionally - in my experience, plants with C. purpurata ancestry are more likely to do it, but this is just anecdotal and based on a small sample size.  These flowers will not be as nice as those I expect next year but at least I will get to see the coloration.
