아래 FNA 기재문에서 2개의 아종을 이야기하고 있지만 큰 의미는 없는 것으로 판단된다. 국표식에서 아종 Oxalis triangularis subsp. papilionacea (Hoffmannsegg ex Zuccarini) Lourteig를 '나비사랑초'라고 름을 붙였지만 그냥 '사랑초'로 부르는 것이 좋겠다. 국표식에는 '사랑초'는 나오지 않는다.

두 아종을 굳이 구분하자면 위의 종은 꽃받침이 예두이고 꽃잎이 꽃벋침의 3배 이상으로 길어보이는 점으로 보아
O. triangularis subsp. triangularis로 보인다

학명 이명 : Oxalis palustris A. St.-Hilaire; O. papilionacea Hoffmannsegg ex Zuccarini; O. regnellii Miquel; O. triangularis subsp. papilionacea (Hoffmannsegg ex Zuccarini) Lourteig(국표식에서 나비사랑초)
Herbs perennial, acaulous, rhizomes present, <branching, short, 1 cm diam., densely scaly>, stolons absent, bulblets sometimes present, clustered; bulb scales (1–)3-nerved, <margins glandular>. Leaves basal, <rarely absent at flowering>; petiole 12–20 cm; leaflets 3, dark purple, commonly with lighter violet splotches(얼룩 , 큰 반점) radiating from midvein adaxially, obtriangular to obovate-triangular, (20–)30–50(–60) mm, lobed 1/10 length or apex merely notched, <lobes apically truncate to slightly convex>, surfaces glabrous, oxalate(옥살산) deposits absent or in short, marginal lines on both sides of notch. Inflorescences umbelliform cymes, (1–)2–5(–9)-flowered; scapes 15–35 cm, glabrous. Flowers heterostylous; sepal apices with 2 orange tubercles; petals white to pinkish or pale purple, 15–22 mm. Capsules ovoid-ellipsoid, 12–18 mm, glabrous.
Flowering Apr–May. Disturbed sites, near gardens; 0–100 m; introduced; Fla., La.; South America (Argentina, Bolivia, Brazil, Paraguay, Peru).
In East Feliciana Parish, Louisiana, north of Baton Rouge, Oxalis triangularis has spread from a planter pot into adjacent woods (G. F. Guala, pers. comm.). In Leon County, Florida, a population is growing and slowly spreading at the edge of a woodland remnant within the city of Tallahassee (L. C. Anderson, pers. comm.).
A. Lourteig (2000) recognized two subspecies sympatric over much of their native ranges (as cited, subsp. triangularis in Argentina, Bolivia, Brazil, and Paraguay, subsp. papilionacea in Bolivia, Brazil, Paraguay, and Peru) and differing by the following contrasts: subsp. triangularis has sepals acute, oxalate tubercles small or absent, and petals white to purplish, three to four times longer than the sepals; subsp. papilionacea has sepals obtuse to subacute with oxalate tubercles thickened, and petals pink to purplish, rarely white, about two to two and a half times longer than the sepals. With these subtle differences and broad sympatry, it seems probable that only a single evolutionary entity exists. In any case, the few North American collections studied here would be Oxalis triangularis in the strict sense. Forms of O. triangularis are sometimes recognized as “atropurpurea (very purple)” but apparently this is a horticultural name.
