10/10/97   ADDED   Phacelia intermedia

03/31/98  1COMMENT According to Dr. Richard Spellenberg the distinction between Gilia mexicana, 
G. flavocincta (also called G. opthalmoides), and G. sinuata is not easily made with the 
references we have available to us.  Characters such as (1)stems clasping vs. not, (2)leaves 
reduces above rosette immediately or gradually, and (3)the extent to which the corolla tube is 
exerted beyond the calyx are highly variable and do not distinguish the species.  A taxonomic 
review needs to be done on this group, and until then, Dr. Spellenberg suggests we just refer 
to them as the Gilia sinuata group, which includes these 3 potential species.  Based on this 
recommendation, Gilia spp. will in the future be identified as Gilia sinuata with the 
understanding that it refers to the G. sinuata group. [See Comment of 01/24/07 below.(JPA)]

                   standardized to first four letters of genus followed by sequence number
                   (usually 1) to identify it as an unknown.  These codes are no longer embedded
                   in the plant species list.

                      Vegetation Transects, Spring 2003. Unable to collect voucher as there was only
                      one plant found and it was in a quad. I.d. based on flowering stage as well as
                      later fruiting stage. A digital photo was taken also.
03/16/04   CHANGED Carbon pathway from C4 to C3 for Vulpia octoflora (Walt.) Rydb. as noted on page 
69 of Cornelius, Joe M., Paul R. Kemp, John A. Ludwig, and Gary L. Cunningham. 1991. The

Voucher collected 5/19/05 by Jamie Lamit and placed in LTER herbarium. Identification by Richard 
Spellenberg of NMSU, Biology Dept.
01/23/07           Corrected page formatting. [JPA]
01/24/07   CHANGE  The 3 species of Gilia (G. sinuate, G. Mexicana, G. flavocincta) were all 
lumped as G. sinuate beginning in 1998. See change entries above dated 03/31/98 and 09/09/99. 
However, the field key to these 3 species is now thorough enough to identify the 3 individual 
species. This has been verified with Dr. Richard Spellenber. As a result, the GISI code used 
for the 3 species is now changed to represent the individual species as given below. The expanded 
field key used is that found in Kelly Allred's "A Field Guide to the Flora of the Jornada Plain", 
Fifth Edition, June 2005.
           CHANGED  GISI  G. sinuata Dougl.
                TO  GIME  Gilia mexicana A.&V. Grant

of NMSU, Animal & Range Sciences Dept. Very common in Rio Grande valley but not previously listed 
for the Jornada Basin. Noted to occur at NPP site C-GRAV, Quad 15 on February 6, 2007.
02/11/07   CHANGED  Hordeum murinum: Updated information per Kelly Allred. This is a cool season 
grass (C3) typically flowering February-April, but sometimes as early as December as as late as 
May, depending on temperature and precipitation. (JPA
03/26/07   CHANGED  Poa fendleriana (Steud.) Vasey subsp. Changed carbon pathway from C4 to C3 per 
Kelly Allred. All Poa genera are C3. The error was identified by Karen Brown of LANL on 3/26/07.
04/03/07   ADDED    Linaria texana Scheele. Collected 3/29/07 by Chandra Tucker-Britt next to 
LTER-I Control Transect path between stations C81 & C 84 adjacent to LTER NPP G-SUMM site. 
Identification by Kelly Allred of NMSU, Animal & Range Sciences Dept.
04/03/07   ADDED    Cryptantha barbigera (Gray) Greene. Collected outside LTER T-TAYL NPP site

collected (for later i.d.) 10/27/2009 on LTER-I Transect Station T87 plant line transect in EPTR. 
No voucher collected. Identification by Kelly Allred on 12/7/09. Newer authority makes it P. 
filiformis, but retaining nomenclature by Correll & Johnston, it remains P. wrightii.
12/11/09   CHANGED  Changed Phaseolus atropurpureus DC. to P. acutifolius Gray var. acutifolius 
based on identification by Kelly Allred on 12/11/09.
09/11/10   DELETED  Chenopodium atrovirens Rydb. (Cheno.) CHAT   A   FORB  PC   SP-SU   C3    
NAT  CJ 535 From Key to the Flora of the Jornada Basin by Kelly Allred: "Earlier reports of 
Chenopodium atrovirens from the plains area were in error; that is a species of middle- to 
upper elevations in the mountains."
09/11/10   CHANGED      Changed spelling of Descurainea pinnata to Descurainia pinnata.
09/12/10   DELETED  Euphorbia species  EUSP   A   FORB  BS       SU   C4    NAT  CJ 955
                    This is no longer a valid code for an unknown Euphorbia species.
09/12/10   CHANGED  Changed spelling from Gallium microphyllum to Galium microphyllum.
09/13/10   DELETED  Chenopodium cycloides A. Nels.   CHCY   A   FORB  MR     SU    .    NAT  
CJ 534
