This paper gives an overview of all the apomictic plant groups and how taxonomists have classified them: http://www.ibot.cas.cz/hieracium/studygroup/pdfs/1017_1040_Majesky.pdf
Raspberries:
The genus is traditionally classified into several subgenera, but only one – subg. Rubus – represents a group with predominantly asexually reproducing species (Alice & Campbell, 1999). … Taxonomic treatment of the apomictic species involved several approaches (for a review, see Weber, 1996).

Dandelions:
The section is the key infrageneric category for sorting the large diversity of Taraxacum species (). … A section contains one or a few diploid sexual taxa and a number of morphologically distinct apomictic polyploids (for which more than 3000 names have been published). However, there are several sections which contain only sexual or only asexual taxa (Kirschner & Štěpánek, 1996). Sexual taxa are described as species with a wide distribution (but restricted in comparison to apomicts) and with large phenotypic and genotypic variation (). Polyploid apomictic taxa are recognized based on their distinctive morphology and are traditionally classified as microspecies. … Some botanists, however, prefer to refer to broad species/species aggregates … This practice, however, is not correct [as it’s been done in the past, at least], as used taxon names do not always represent the types, based on which sections were described and defined, and thus should not be used instead of a sectional name ().

Here’s the Kirschner & Štěpánek, 1996 paper cited in there: https://www.jstor.org/stable/4181475
In large areas agamospermy is known to predominate absolutely (Siberia, N Europe, N
America) but sexuality is by no means rare in the genus (only sexuals are known among
native temperate taxa in the southern hemisphere). …
We should mention that the absolute majority of sections or subsections without any known
sexuality (about 25 groups) are arctic or other northern groups, or are limited to smaller areas
in high mountains. On the other hand the most widely distributed derived or precursor European
and Asian sections usually exhibit a certain, often considerable degree of sexuality (Tab. 1).
