THYME-LEAVED SPEEDWELL

(Humifusa serpyllifolia ssp. serpyllifolia)

Often prostrate on the ground with the flowering stalks making an attempt at being upright.

This sub-species ssp. serpillifollia has leaves which are ovate to elliptical in shape (whereas those of ssp. humifusa are ovate to orbicular).

This too is sprawling around on the ground, but it isn't up a mountain where specimens of Mountain Speedwell also crawl over the ground.

The racemes are glabrous on this specimen, but can also have hairs but they are not glandular hairs as they are in Mountain Speedwell shown nearer the foot of this page. At least half of the flowering stem on ssp. serpyllifolia is erect (which is not so for Mountain Speedwell which is mostly sprawling).

[A different plant encroaches near botton left having cut leaves]

The corolla is between 5 to 8mm across for this sub-species.

The flowers are in a long spike, some not yet opened. The leaves ovate to elliptical in shape, with untoothed edges (although some may be ever so slightly bumpy on the edge).

This specimen bears fruits! They are heart-shaped with a nick at centre-top and a style with stigma greatly exceeding the top.




MOUNTAIN SPEEDWELL

(Humifusa serpyllifolia ssp. humifusa)
an [RR] sub-species of the above

Possessing hairs (even glandular hairs), being 1/3rd of the way up a mountain, having fewer flowers (less than 12 as opposed to greater than 12 flowers for the much more ubiquitous ssp. serpillifoliia at the top of the page) and having flower stalks longer that the calyx tube these are thought to be ssp. humifusa.

NOTE: your Author is holding this up in the air to obtain a better photo of it - it must have been sprawling around on the ground.

This sub-species also differs by possessing racemes with glandular hairs (near the top of the stem in this photo). It also has larger flowers 6 to 10mm across which are supposed to be a deeper blue (as opposed to 5 to 8mm across for ssp. serpillifoliia).

Unfortunately, to confuse botanists even more than they are already - those specimens of ssp. serpillifoliia) which are growing in mountains often look like Mountain Speedwell (ssp. humifusa) in that they also have bluer corollas and more procumbent stems, fewer flowers and can have glandular hairs - which Prof. Clive Stace says need more investigation... Er Umm... Don't forget: If it looks like a duck and quacks like a duck then it's a saxaphone!
