One species, Abutilon theophrasti
(velvetleaf), is an introduced annual species that primarily occurs in open disturbed grassland habitats or at the edge of the woodland phase; while the other, Malvaviscus arboreus var.

We studied naturally-occurring heliothine populations over a 3-year period in 2 different geographic locations in plots of garbanzo bean (Cicer arietinum L.), upland cotton (Gossipium hirsutum L.), and velvetleaf (Abutilon theophrasti
Medikus) finding that garbanzo bean produced significantly higher numbers of tobacco budworm and bollworm larvae and adults as compared to the other 2 plant species.

niveles de germinacion mas altos en los grupos de tamanos de semilla grande (7,0-7,9mg y 8,0-8,9mg), probablemente debido a la mayor concentracion de nutrientes en las semillas, y niveles de germinacion mas bajos en los grupos de semillas mas pequenas (<6,0mg).
[C.sub.3] broadleaves were composed almost entirely (>95%) of three species; lambsquarters (Chenopodium album L.), velvetleaf (Abutilon theophrasti
Medik.) and Virginia copperleaf (Acalypha virginica L.); [C.sub.4] broadleaves were exclusively redroot pigweed (Amaranthus retroflexus L.) and Ca grasses consisted of barnyard grass [Echinochloa crus-galli (L.) R Beauv.], Bermuda grass [Digitaria sanguinalis (L.) Scop.] and foxtail (Setaria spp.).
Greenhouse growth studies were conducted to determine if pHBA levels near the growth-inhibition threshold altered mineral content of velvetleaf (Abutilon theophrasti
Medic.) tissue, and if the level of available boron (B) modified pHBA effects.
As a more concrete example of its usefulness, we calculated S for data from Shumway and Koide (1995) on the effect of mycorrhizae and plant density on the number of capsules produced by Abutilon theophrasti
The most prevalent weeds on ARP land were foxtails (Setaria spp.; 40% of plantings), velvetleaf (Abutilon theophrasti
; 38% of plantings) and common cocklebur (Xanthium strumarium; 17% of plantings).
