Summary from transcript: Shekwasha retained healthy lower stems but showed tip dieback and poor leaf condition; it appeared better than nearby Keraji (15:29–16:22).

Individual scorecard image for Shekwasha Mandarin. The printed preference ratings are sweetness 7.5/10, sourness 7/10 and bitterness 8/10; the linked fruit reference preserves these original ratings alongside catalog numeric scores. Sweetness is stored as printed; sourness and bitterness use 10 minus the printed score. Any Brix or pH printed on the card is a separate reading, not derived from ratings. Sample method and harvest date are not stated unless noted in the reference.

Summary from transcript: The presenter reviews Shekwasha fruit grown in a North Carolina unheated greenhouse-type structure and reports 14 °Brix, pronounced sourness, light sweetness, and slight astringency. Individual fruit weights are read aloud as 29.7 g, 29.6 g, and 16 g; those readings calculate to a 25.1 g mean, while the presenter gives an approximate average of 22–23 g. The matching Shekwasha scorecard image carries 23 g, 14 °Bx, a pH estimate, and the same rating rows, so this video and card are the same report, not independent taste evidence. Captions cover 0:01–28:04. The presenter estimates pH only; he reports his one-year tree did not survive 10°F (22:32–22:54).

Summary from transcript: The presenter reviews a small Shekwasha fruit purchased from Winterwarm Farms alongside a separate Yuzu. The Shekwasha is reported as 12 g and 13 °Brix, juicy for its size, with light acidity and sweetness and no bitterness. Captions cover 0:01–12:08. This is a separately sourced purchased fruit sample; the presenter’s 5–10°F short-interval estimate applies broadly to both fruits and is not a measured cultivar limit.

IDtools lists several attributed synonyms, including Pectinifera, Seequasia, Shiikuwasha, and Shikasya. It identifies Citrus depressa following Hodgson (1967) and Tanaka via Cottin, while also listing an uncertain C. reticulata × C. tachibana classification attributed to Swingle and Reece (1967). Its morphology entry describes a compact/dense, non-weeping crown; fruit broader than long, slightly rough/leathery rind, orange flesh, and acidic-sweet taste. These are source descriptors, not sample measurements; the entry presents competing taxonomic treatments rather than resolving pedigree.

This study describes the pummelo–mandarin hybrid rootstock S10, with Shekwasha and Hirado Buntan Pink material in its reported breeding background, then evaluates S10-derived seedling/rootstock material and grafted Valencia scions under greenhouse salinity and HLB treatments. The tested open-pollinated S10 seedling cohort included zygotic lines with unknown pollen parentage and a nucellar line like the seed parent. This supports Shekwasha's bounded use as a parent in S10 development, not an ancestry change or intrinsic Shekwasha performance claim.

Grosser et al. list Shekwasha mandarin (C. depressa) as an embryogenic parent in somatic-fusion combinations with Hirado Buntan Pink, an HBP seedling, and Chandler pummelo. The reported plant counts, low nursery-vigor ratings, reduced flushing/shorter internodes, and embryo-induction observations concern regenerated somatic hybrids and tissue-culture outcomes, not Shekwasha trees or fruit.

This editorial overview describes Shikuwasa as an Okinawan citrus, gives an August–February harvest period, and discusses culinary uses of juice in marinades, sauces, desserts, and drinks. It characterizes flavor broadly as tart with hints of sweetness and bitterness and mentions a fresh, slightly floral aroma. It supplies no botanical name, accession, sample, or measurements; these are broad editorial claims, not Shekwasha-specific sample results. Health/beauty marketing claims are not used.

In a post about fruit from a received shipment, Skandiberg reports Shekwasha at Brix 8 with one seed. The author describes easy peeling, very juicy flesh, and a camphor/menthol-like aroma noticed in later fruit. The post says none of the fruit was from the author’s own trees; orchard provenance and sample count are unstated.
