Kookoolau or Molokai kookoolauAsteraceaeEndemic to the Hawaiian Islands (Molokai only)IUCN: Critically EndangeredOahu (Cultivated)Early Hawaiians used the leaves in hot teas and tonics. Today, all species of kookoolau can be brewed as a tonic and each are said to have distinct flavors. Regarding Bidens spp., Isabella Abbott comments that "I find that the roughly half a dozen species common in Hawaii offer two or three slightly different flavors, each a bit more subtle than commercial black tea." ("Lau Hawaii: Traditional Hawaiian Uses of Plants")EtymologyThe generic name Bidens is derived from the Latin bi, two, and dens, teeth in reference to the pappus awns or collective bristles on the achenes (fruit, seeds).The specific epithet wiebkei is named for Henry Wiebke, botanist and fellow plant collector with botanist Otto Degener in the Hawaiian Islands.

Also called Beggarticks or Beggar-ticks. In Utah, this species is rather uncommon and is restricted to mainly the northern portion of the state along the Wasatch Front in Box Elder, Cache, Millard, Morgan, Salt Lake, Utah and Weber counties, this species has been treated in our floras as Bidens comosa (A. Gray), Wiegand (syn. B. connata var. comosa). It grows in mainly moist meadows and the edges of wetlands at low elevations (for example, in Utah County near the shore of Utah Lake). In Salt Lake County, there are few places that are known where it still remains.While the name Bidens comosa was synonymized in the Vol. 21 of Flora of North America (FNA) published in 2006, under Bidens tripartita, there appear to be enough questions about that treatment to leave this for now as B. comosa.The FNA treatment includes B. comosa as synonym without explanation. It recognizes B. connata on the one the hand with various varietal synonyms provided, but never mentions B. connata var. comosa; perhaps just an oversight, but a glaring one. It then also states that it B. connata perhaps should be included in B. tripartita.It seems to miss some key characters that were described by Intermountain Flora Vol. 5 (1994) and well-illustrated there. For example, note the four (and sometimes five) lobed disk flowers as pictured above. Flowering heads are erect and not nodding later on.And, as reported in both Intermountain Flora Vol. 5 (1994) IF and A Utah Flora (4th ed. 2008), B. comosa is reported as 2n=24. But yet FNA says 2n=48 for B. tripartita (and same for B. connata). That raises even more questions. Our plants also do not look like many examples of plants referred to as B. tripartita. Our plants definitely don't have triparte leaves (they may in some cases start to show that but never seem to fully develop past some vestigial remnant it seems). They seem to mostly be <= 6 dm (about two feet) tall although IF provides a much larger range. Also, the calyculi in many examples of B tripartita have a whorled/angled appearance that ours do not. And they have leaf hairs that ours lack, and more prominent teeth. FNA simply says sometimes they are ciliate, but many "tripartita" plants seem to often have long terminal leaf hairs.More study and DNA/genetic analysis is needed before this is lumped with something else.July 14, 2012, Salt Lake Valley east of the Jordan River, Salt Lake County, Utah, approx. 4,295 ft. elev.The leaves of another Bidens, B. frondosa can be seen here in the upper righthand corner.

He planted many of the plants he collected at Queen's Hospital and on his own property in Nuuanu. After moving back to Germany the property was sold to his neighbors Thomas & Mary Foster. Today, it is known as the Foster Botanical Gardens.The subspecific name polycephala is from the Greek poly, many, and cephalus, headed, referring to having many more floral heads when compared with subsp. hillebrandiana.
