Zygia longifolia

Plate 1 figs. a–h · 3 observations

This species has been photographed under an open licence only 3 times, so some figures below are different views of the same plant, taken on the same day, rather than different individuals. They are usually different parts of it: the leaf, the flower, the bark.

Zygia longifolia, photographed by Quentin Groom — fig. a Quentin Groom, CC0 1.0 / 2016-12-10 / obs. 5814169

Zygia longifolia, photographed by Andres Hernandez — fig. b Andres Hernandez, CC BY 4.0 / obs. 193435055

Every figure is a research-grade observation under CC0, CC BY or CC BY-SA, rehosted with the photographer’s name, the licence and the observation it came from. Photographs under a NonCommercial licence are excluded from this site and are never stored, which costs us a great many pictures and is not negotiable.

Native range 12 botanical countries

Native distribution of Zygia longifolia, after Kew’s World Checklist of Vascular Plants. Introduced, extinct and doubtful records are excluded, so this is where the plant is from, not everywhere it now grows.

Where it actually grows measured, from 53 observations

Condition	5th percentile	Median	95th percentile
Coldest month, mean daily low	14.9 °C	18.7 °C	23.2 °C
Warmest month, mean daily high	24.6 °C	27.8 °C	31.4 °C
Annual rainfall	1,841 mm	2,765 mm	5,241 mm
Rainfall in the driest quarter	76 mm	230 mm	726 mm

It is not found anywhere that gets close to freezing. This is not care advice and it is not a forecast. It is a measurement: we sampled the climate at every one of the 53 research-grade observations of Zygia longifolia that carry a coordinate, and this is the range those places actually span. The 5th and 95th percentiles are used rather than the minimum and maximum, because a single cultivated specimen in a heated conservatory should not widen a tropical plant's range to the Arctic.

This is not a hardiness zone. A USDA zone is the average annual extreme minimum temperature. The figure above is the mean daily minimum of the coldest month, which is a different quantity and is typically far warmer. Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.

A synonym is not an error. It is a record of botanists disagreeing, in print, about where this plant belongs. Each of these was somebody’s considered answer.
