Well that's totally true. I guess the second link is helpful. The question I guess it are those true varieties of the SB or just other varieties of habaneros. Most don't have the characteristic bonnet shape. I wonder if they have the bonnet flavor.
The only ones that have the shape are the "true jamaican" the SB red and yellow. The rest don't look like bonnets at all.
The term Scotch bonnet has often been mis-used over the years like you just mis-used "habanero" to describe all chinenses.
As the article states, Scotch bonnets don't always have the Tam or bonnet shape, but those that do are graded higher. Pod shape can differ dramatically even on the same plant
"Scotch bonnet graded according to quality of the product. Grade A (or Grade 1) is better than Grade B (or Grade 2). A Grade A Scotch bonnet is expected to:
•have a cup and saucer shape or look like a Scottish man's bonnet (tam)
•have four or five lobes
•be 1.5 inches wide
•have a stalk no longer than 1 1/4 inches long
•be without blemishes on the skin
•be free of chemical residue"
"The Jamaican government is currently working with agronomists at the Scientific Research Council and the Ministry of Agriculture to save the Scotch pepper which is under threat from the use of inferior seeds, the use of the name Jamaican Scotch bonnet to describe peppers that are not real Scotch bonnet, inferior quality products and inability to meet demand. In addition, the fumigation that is required for entry into the United States results in quicker spoilage.
The Ministry of Agriculture, Rural Agricultural Development Association and the Scientific Research Council are all working to ensure that the Scotch bonnet pepper industry survives. One of the strategies being developed is the sale and distribution of top-quality Jamaican Scotch bonnet seeds to farmers. "
