''P. chartacea ssp. chartacea'' is a gap specialist, and can be found in high densities in gaps of rosemary scrubs. Rosemary scrubs experience fire in intervals of 10 to 100 years. Florida rosemary (''Ceratiola ericoides'') leaches allelopathic chemicals from its roots which can inhibit germination and kill neighboring herbs. It has been observed that the frequency increases post-fire, this is possibly due to ''C. ericoides'' individuals being killed by fire. <ref name="Weekley and Menges 2003"/> Occurrence and density of ''P. chartacea ssp. chartacea'' declined with time since fire in rosemary scrubs,<ref name="Schafer et al. 2010"/> this is possibly due to the increase of ''C. ericoides''.

Synonyms: Nyachia pulvinata Small.[1]

Varieties: Paronychia chartacea Fernald var. minima (L.C. Anderson) R.L. Hartman.[1]

Description

A description of Paronychia chartacea is provided in The Flora of North America.

Distribution

There are two isolated subspecies. P. chartacea ssp. chartacea can be found in scrub habitats of the Florida peninsula, this subspecies is a short-lived perennial. P. chartacea ssp. minima is found in the karst region of the northwest Florida panhandle, it has been described as somewhat less pubescent than P. chartacea ssp. chartacea, and is annual.[2][3] Much of the distinction between the two subspecies is minimal.[4]

Ecology

Habitat

FSU Herbarium specimen have documented P. chartacea in sand pine scrubs with Hypericum cumulicola, herbarium labels do not specify what subspecies these specimen are. It can be inferred that the individuals growing in this habitat are of P. chartacea ssp. chartacea based on previous knowledge of the distribution of the two subspecies. P. chartacea ssp. chartacea is restricted to the Lake Wales Ridge in Highlands, Polk, Osceola, Orange and Lake Counties. Within this range, it is found growing in sand pine scrubs and Florida rosemary scrubs.[3] Soils of this area include those of St. Lucie and Archbold soil types.[5] It is a gap specialist, occurring at greater densities in areas of open bare sand, and is one of the most abundant species in the rosemary scrub seedbank.[6]

P. chartacea ssp. minima is found in nearly pure stands in the karst region of the Florida panhandle (Washington and Bay counties). It has been observed growing with Amphicarpum muhlenbergianum, Bulbostylis barbata, B. ciliatifolia, Chrysopsis lanuginosa, Eriocaulon lineare and Hypericum lissophloeus.[3]

Phenology

Flowers August through November[7] and fruits in October[8]

Seed bank and germination

Germination of P. chartacea ssp. chartacea is highest in intact scrubs because invertebrate predators may use the low shrub cover of the rosemary scrubs to hide from carnivorous predators which are less likely to forage in degraded scrubs.[9] Schafer et al. 2010 found it to be one of the most abundant species in the rosemary scrub seedbank. It is an annual and obligate seeder with germination frequency increasing post-burn.[10] Seedlings have been observed to germinate over a broad range of months.[11] High density in the seed bank and above ground cover has been observed in the first ten years after fire with highest density three years post-fire.[12] One study found recently burned and long-unburned sites result in low seed density, while sites with six-ten years since fire result in high seed density.[12] Paronychia chartacea forms a persistent soil seed bank.[13]

Fire ecology

P. chartacea ssp. chartacea is a gap specialist, and can be found in high densities in gaps of rosemary scrubs. Rosemary scrubs experience fire in intervals of 10 to 100 years. Florida rosemary (Ceratiola ericoides) leaches allelopathic chemicals from its roots which can inhibit germination and kill neighboring herbs. It has been observed that the frequency increases post-fire, this is possibly due to C. ericoides individuals being killed by fire.[10] Occurrence and density of P. chartacea ssp. chartacea declined with time since fire in rosemary scrubs,[6] this is possibly due to the increase of C. ericoides.

Pollination

Paronychia chartacea was observed at the Archbold Biological Station to host sweat bees from the Halictidae family such as Lasioglossum miniatulus, L. nymphalis and L. placidensis, spider wasps from the Pompilidae family such as Anoplius semirufus and Episyron conterminus posterus, thread-waisted wasps from the Sphecidae family such as Tachysphex apicalis and T. similis, and wasps from the Vespidae family such as Leptochilus krombeini and Parancistrocerus salcularis rufulus.[14]

Conservation, cultivation, and restoration

P. chartacea ssp. chartacea is limited to the Lake Wales Ridge, which is threatened due to fragmentation from urban and agricultural development. The loss of the scrub habitat is the primary reason this subspecies is threatened.[3] By 1980, more than two-thirds of the historic scrub habitat was destroyed.[15] Fire suppression is also threatening to this species.
