Bomarea dulcis | BotanAI

Plate 1 figs. a–g · 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.

Bomarea dulcis, photographed by Aira Francisca Faúndez Fallau — fig. a Aira Francisca Faúndez Fallau, CC BY 4.0 / 2013-09-09 / obs. 95376617

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.

The specimen a real sheet, in a real collection

Herbarium: Royal Botanic Gardens, Kew
Accession: K000400917
Filed as: Bomarea dulcis (Hook.) Beauverd
Det. by: Hofreiter, A.
Collected: Mathews
Origin: PE
The sheet: View the digitised specimen (CC BY 4.0)

A real pressed plant, in a real collection, under the accession number above. Not an illustration of one. The holding institution does not serve this sheet’s image to third parties, so there is no photograph here. The record is real and the link goes to it. Where we hold no openly licensed sheet for a species this section is simply absent, and where a sheet never recorded who determined it, that field stays empty rather than being filled in. Roughly half of all herbarium sheets never recorded a determiner, which is ordinary.

Native range 3 botanical countries

Native distribution of Bomarea dulcis, 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.

Region	TDWG code	Continent
Bolivia	BOL	SOUTHERN AMERICA
Chile North	CLN
Peru	PER

Region boundaries approximated from Natural Earth (public domain) and mapped to TDWG World Geographical Scheme for Recording Plant Distributions (WGSRPD) level-3 botanical countries (Brummitt 2001). Indicative, not the official WGSRPD geometry.

Where it actually grows measured, from 52 observations

Condition	5th percentile	Median	95th percentile
Coldest month, mean daily low	-6.0 °C	-1.7 °C	5.1 °C
Warmest month, mean daily high	8.8 °C	12.1 °C	17.1 °C
Annual rainfall	429 mm	1,394 mm	2,322 mm
Rainfall in the driest quarter	9 mm	55 mm	168 mm

It is found where winters bring hard frost. This is not care advice and it is not a forecast. It is a measurement: we sampled the climate at every one of the 52 research-grade observations of Bomarea dulcis 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.
