Congea tomentosa is a large tropical evergreen vine, commonly referred to as wooly congea, shower orchid, or shower of orchid. (Despite the name, it is not closely related to orchids). It is called lluvia de orquideas or terciopelo in Spanish, krua on in Thai, and rong bao teng in Chinese. Native to Myanmar and Thailand, it can be found elsewhere in South Asia, including Laos, Vietnam, Malaysia (Kedah), China (Yunnan), Bangladesh, and India (Assam, Manipur, Tamil Nadu, and West Bengal). Its native habitat is mixed forests 600–1200 meters above sea level.Kew World Checklist of Selected Plant FamiliesFlora of China Vol. 17 Page 49 绒苞藤 rong bao teng Congea tomentosa Roxburgh, Pl. Coromandel. 3: 90. 1820. This tropical vine has been naturalized elsewhere, including the islands of the Caribbean, southern Florida, and southern California. In the United States, wooly congea can be grown outdoors in USDA zones 10 and 11. It does not tolerate frost. The plant can grow to 3–5 meters (10–16 feet) in cultivation and even larger in its native state. The stems, leaves and bracts are covered with fine, downy hairs. The leaves are light green in color, 6-8 inches (15.2-20.3 centimeters) long, and quite attractive. They are evergreen with prominent veins and are arranged in opposite pairs. The actual flowers are tiny and inconspicuous, borne in the center of three showy white or violet 1 inch (2.5 centimeter) long bracts that look like velvety propellers. From late winter to spring it produces sprays of showy flowers. The bracts gradually change color through pink, lavender, and finally grey over the course of several weeks.

The complete instruction manualCongea tomentosa carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
