POPULAR GUIDES TO <strong>TEXAS</strong> PLANTS/INTRODUCTION 257<br />

Texas taxa new to science were described, and an additional 86 new state records were<br />

discovered (27 native, 59 introduced) (B. Lipscomb, unpublished data). Examples of East Texas<br />

native species new to science include Agalinis navasotensis (Canne-Hilliker & Dubrule 1993),<br />

Carex perdentata (Jones 1994b), Calopogon oklahomensis (Goldman 1995), Carex ozarkana<br />

(Rothrock & Reznicek 1996a), Baptisia ×variicolor (Kosnik et al. 1996), Crataegus nananixonii<br />

(named for Elray Nixon—Phipps & O’Kennon 1997), Spiranthes eatonii (Brown 1999), Carex<br />

shinnersii (named for the late Lloyd Shinners—Rothrock & Reznicek 2001), Liatris aestivalis<br />

(Nesom & O’Kennon 2001), Liatris glandulosa (Nesom & O’Kennon 2001), Nemophila sayerensis<br />

(endemic to the “fossil beach sand areas” in east central Texas—Simpson et al. 2001),<br />

Pseudognaphalium austrotexanum (Nesom 2001), Spiranthes sylvatica (Brown 2001), Carex<br />

kraliana (named in honor of Robert “Bob” Kral “in recognition of his contributions to the<br />

knowledge of the flora of the southeastern United States, particularly its great diversity of<br />

sedges”—Naczi et al. 2002), and most recently, Yucca cernua (a striking Texas endemic with<br />

inflorescences to 4 m tall—Keith 2003). Native species recently discovered for the first time<br />

in Texas (all in East Texas) include Triosteum perfoliatum (Holmes et al. 1999), Houstonia longifolia<br />

(Singhurst & Holmes 2001b), Verbesina walteri (Singhurst & Holmes 2001a), Bidens alba<br />

(Brown & Elsik 2002), Calycanthus floridus (Brown & Elsik 2002), Cuphea viscosissima<br />

(Brown & Elsik 2002), Iris fulva (Singhurst et al. 2002a), Lyonia lucida (Brown & Elsik 2002),<br />

Rhynchosia tomentosa (Brown & Elsik 2002), Silene virginica (Singhurst et al. 2002a), Agalinis<br />

harperi (Keith & Hays 2003), Geocarpon minimum (Keith et al. 2004; J. Singhurst & E. Keith,<br />

pers. comm.; a federally threatened species), Ctenium aromaticum (J. Singhurst, pers. comm.<br />

2003), and Decumaria barbara (J. Singhurst, pers. comm. 2004). This continuing discovery<br />

of species new to science and new to the state emphasizes the need for additional collecting<br />

and habitat conservation in East Texas and Texas as a whole.<br />

POPULAR GUIDES TO <strong>TEXAS</strong> PLANTS<br />

In addition to the numerous technical works on Texas plants, a large number of popular<br />

guides and references have been published, giving a wide audience access to information<br />

about the state’s flora. Material on plant identification, landscaping with native plants, horticulture,<br />

edibility and, other uses can be obtained from these sources. Many contain material<br />

(e.g., photographs, landscaping information) not available in the more technical works and<br />

are thus of great value. A list of such publications is given in Appendix 14. B
