This species is closely related to Rubus calycinus[].
The genus Rubus, (especially the blackberries, which are often loosely referred to as Rubus fruticosus agg.) presents some of the most difficult taxonomic problems. This is partly due to the frequency of polyploidy; also to the frequent occurrence of hybridization; and also due to apomixis, where minor differences between plants are preserved because seedlings are genetically identical to their parent. As a result, differences of opinion on the number of species to be recognized from a given region can vary tremendously (for example, a treatment by M. L. Fernald[] in 1950 recognized 205 species for the northern half of the eastern United States plus parts of southeastern Canada, whilst H. A. Gleason and A. Cronquist in 1991 recognized only 25)[]. Where possible, a relatively conservative approach is taken here[].

General Information

Rubus pectinellus is a low-growing, perennial plant with creeping, semi-woody main stems up to 2 metres long that root at the nodes and form dense carpets of growth on the ground. The fruit is produced on erect, sparsely branched or unbranched lateral stems up to 20cm tall that grow from the leaf nodes[, ].
The edible fruit is gathered from the wild and used locally. It is said to be one of the best tasting species in the Philippines[].

Cultivation Details

A plant of the subtropics to tropics, growing at moderate to high elevations.
Species in this genus are generally easily grown in a good well-drained loamy soil in sun or semi-shade[, , ].
Plants in this genus are notably susceptible to honey fungus[].

Edible Uses

Fruit - raw or cooked. A fine flavour and good quality[, , ]. The globose, red fruit is 10 - 15mm in diameter[].

Propagation

Seed - germinates best if given a period of cold stratification prior to sowing in containers. Stored seed requires one month stratification at about 3°c and is best sown as early as possible in the growing season. Prick out the seedlings when they are large enough to handle and grow on until large enough to plant out.
Cuttings of half-ripe wood in a frame[].
Tip layering towards the end of the growing season
Division just before the plant comes into new growth or as it enters dormancy[].
