FLORISTICS OF XERIC SANDHILLS IN EAST TEXAS 

B.R. MacRoberts & M.H. MacRoberts 
Bog Research, 740 Columbia, Shreveport, Louisiana 71 104 U.S.A. 

ABSTRACT 

The flori sties and edaphic conditions of two east Texas xeric sandhills are 
described. This community occurs in central and northwestern Louisiana, east 
Texas, and southern Arkansas. The sandy soil is nutrient poor and porous. 
Water and air move rapidly through it causing rapid drying. In presettlement 
times, sandhills were probably fairly common in the West Gulf Coastal Plain, 
but because of fire suppression, grazing, agriculture, oil exploration, and 
agroforestry, this community has been badly damaged and greatly reduced m 
extent 

KEY WORDS; Sandhills, xeric, floristics, Sabine National Forest, Texas 
INTRODUCTION 



Like so many plant communities of the West Gulf Coastal Plain, there is little 
published information on xeric sandhills (synonyms: sandylands, oak-farkleberry 
sandylands, xeric sandy woodlands, bluejack oaJc-pine series) (see Diamond ei al. 
1987; Harcombe et al. 1993; MacRoberts & MacRoberts 1994, 1995 for previous 
literature). This community is listed as endangered by both the U.S. DA. Forest 
Service and the Texas Organization for Endangered Species because it is potentially 
vulnerable to extirpaticm or severe degradation. Most sandhill communities have been 
destroyed in northwestern Louisiana (MacRoberts & MacRoberts 1995) and the 
community is imperiled in the state (Teague & Wendt 1994; Louisiana Natural 
Heritage Program 1988). 

Xeric sandhills of the West Gulf Coastal Plain appear to be similar to turkey oak 
sandhill forests in the East Gulf Coastal Plain except for the absence of several key 
species such as turkey oak {Quercus laevis Wait) and wiregrass {Aristida stricta 
Michx.) and the presence of several western elements not found in the east (Stout & 
Marion 1993). 



PHYTOLOGIA January 1996 volume 80(1): 1-7 



Sandhills occur mainly in Tertiary marine deposits on ridge tops and upper slopes, 
and on Pleistocene deposits on terraces near streams. The deep sandy soils are of low 
fertility and, because of their porous nature, water and air move rapidly through them 
causing rapid drymg. Overstory, midstory, and herbaceous vegetation is often sparse, 
allowing sun to reach the ground, and in some areas, there are no trees. Reflected 
glare from the sand is often mtense. Trees, typically a combination of overstory pines 
and midstory oaks, are often stimted. Lichens and mosses are usually plentiful on the 
bare soils, and the soils, where undisturbed, are often cryptogamic. 

In order to learn more about this community, we made a study of the vascular flora 
of two xeric sandhills in San Augustine County on the Sabine National Forest. We 
had previously studied xeric sandhills in Caddo and Natchitoches parishes, Louisiana 
(MacRoberts & MacRpberts 1994, 1995) and in this paper we will have occasion to 
compare the two Texas sites to those. 



METHODS 



We visited the two sandhills — San Augustine and FM 1279 — every two to three 
weeks between the autumn of 1994 and the autumn of 1995. The two sites are located 
about 8 km north of San Augustine near the northern border of San Augustine 
County. Both are on the Sabine National Forest. They are only about 200 meters 
apart but are on separate drainages. 

Both study areas are partly open (10% - 50% cover); dominant trees are Quercus 
incana Bartr., Q. steUata Wang., Pinus palustris P. Mill., and P. echinata P. Mill. 
Trees are d"ten stunted and openings occur among wooded areas. San Augustine 
sandhill covers about 4 ha and FM 1279 is about 1 ha. Although the terrain is hilly 
and thus topographically variable, both sites are about 200 meters above sea level. 
They occur on a narrow strip of the Carrizo formation, which becomes more extensive 
to the northwest (Barnes 1967). 

The study sites were selected because they appeared to be of high natural quality. 
Previous work in the area consists of a brief survey designed to locate high quality 
examples of communities occurring on the Natic«al Forests and Grasslands in Texas 
(Orzell 1990). 

We collected and recorded all vascular plants found. We follow Kartesz ( 1994) in 
most instances of botanical nomenclature. Voucher specimens of many of the species 
collected are distributed among ASTC, BRCH, and VDB. 

Soil samples were taken from the upper 15 cm of each sandhill and were analyzed 
by A & L Laboratories, Memphis, Tennessee. 

While the specific fire history of these areas is not known, both sites have been 
regularly burned by the U.S. Forest Service. Half of San Augustine sandhill was 
prescription burned on June 14, 1995. 



MacRoberts & MacRoberts: Roristics of East Texas sandhills 



Annual precipitation averages about 100 cm and is fairly evenly distributed 
throughout the year. Humidity is typically high. In summer, temperatures nse to 35° 
C, which, when combined with short droughts, translates into very hot and dry 
conditions. Especially under these conditions, the ex|X)sed sands become very dry, 
and retlected light is intense. 



RESULTS 



The vascular plants found at San Augustine sandhill [S] and FM 1279 sandhill [F] 
are listed in Table 1. If the species occurs at both sites, no site location is given. 

We list the soil characteristics of the Texas sandhills in Table 2 

The soil on which this community occurs is acidic loamy fine sand of low fertility 
and rapid permeability and belongs to the same soil series described previously for 
Natchitoches and Caddo Parish sandhills (MacRoberts & MacRoberts 1994, 1995). 
The soils are often cryptogamous, with a brittle lichenous crust 



DISCUSSION 



We recorded a total of 1 17 taxa, representing 96 genera and 46 families, for the 
two sites. San Augustine sandhill had 108 sjxcies, and FM 1279 had 102. 
Sorensen's Index of Similanty (IS) between the two sandhills was 88.6, meaning that 
they are the same community. Seven of the species (Cyperus grayioides. Eriogonum 
tongifolium. Paronychia drummondii, Polygonella polygama, Pediomelum 
hypogaeum, Selaginella arenicola subsp. riddellii, and Tetragonotheca ludoviciana) are 
on the Texas National Forests and Grasslands rare sf)ecies list. Asteraceae, Fabaceae, 
and Poaceae dut dominant families, accounting for about 36% of species. 

In 1993 and 1994, we studied a small xeric sandhill in Natchitoches Parish, 
Louisiana (MacRoberts & MacRoberts 1994) for which we recorded 61 taxa Of 
these, 54 (89%) occur in the San Augustine and FM 1279 sandhills. We did not 
compute an IS between this site and those in Texas since species numbers and size are 
not comparable, but clearly the three sites belong to the same community. 

In 1994 and 1995, we studied three sandhills in Caddo Parish, Louisiana 
(MacRoberts & MacRoberts 1995). Since the North Louisiana sites are comparable in 
size and species numbers to the Texas sites, we calculated an IS between them: it is 
66, indicating that, although there are some major differences, the sandhills in Caddo 
Parish and East Texas can be considered the same community.

Orzell (1990), in his survey of the plant communities of the Texas National 
Forests and Grasslands, found the San Augustine sandhills to be of high quality. We 
concur with this assessment. The sandhills we studied in Caddo Parish, Louisiana 
were decidedly inferior to the Texas sites and contained many exotics, which accounts 
for the relatively low IS between them and the Texas sites. The San Augustine 
sandhills compare favorably to some xenc sandhills we have examined in 
Natchitoches f^arish on the Kisatchie National Forest (MacRoberts & MacRoberts 
1994). However, neither of the Texas sites is without damage. A tramway, power 
line right-of-way, an old dump, roads, and plowed firelines mar the San Augustine 
site; while FM 1279 is free of these disturbances, it is fire suppressed. 

The entire area was cut prior to National Forest acquisition in 1936. Part of San 
Augustine sandhill was planted with longleaf pine in the early 1940's, but this seems 
to have failed and the same area was replanted in the late 1940's, again with longleaf 
pine. The rest of the longleaf appears to have seeded in naturally. 

During of the course of this study, we briefly surveyed several other xeric 
sandhills in East Texas, notably in northwest Jasper, southeast Angelina, and southern 
Sabine counties on the Angelina and Sabine National Forests. These often grade 
imperceptibly into upland longleaf pine savannah, but many species fidel to xeric sites 
pinpoint the more xeric extremes. Notably rich in such fidels are the sandhills running 
across the southern part of the Angelina National Forest. Some of these rank in 
quality (and thus rarity) with San Augustine and FM 1279 and should be protected.

INTRODUCCION 



El presente trabajo forma parte de los estudios sobre la flora polinica de la Estacion 
de Biologfa Chamela, Jalisco, Mexico, que Palacios-Chdvez et al. (1986) vienen 
realizando. 

La familia Bignoniaceae comprende 1 10 g^neros y 750 esf)ecies (Lawrence 1951 ), 
distnbufdas en las zonas tropicales de casi todo el mundo, la mayorfa son arboles, 
arbustos o lianas, rara vez hierbas. En la Estaci6n de Biologi'a Chamela, Jalisco, 
Mexico prosperan diez g6neros y diesiseis especies (Lott 1985). 



ANTECEDENTES 



Entre los estudios palinol6gicos de esta familia se tienen los de Erdtman (1966), 
quien descnbe brevemente 25 esjjecies correspondientes a veinte g^neros. Palacios- 
Chdvez (1966) descnbe e ilustra cuatro g^neros y cinco especies del estado de 
Morelos. Mitra(1968) estudia32 g^neros y disungue doce tipos poli'nicos basindose 
en las aberturas, concluye que la familia debe ser polifildtica por la gran diversidad 
palinol6gica y la presencia de tipos poli'nicos pnmiuvos y avanzados y Heusser ( 1971 ) 
estudia cuatro g^neros y cuatro especies para Chile, con breves descnpciones y 
fotomicrograffas. Huang (1972) descnbe brevemente e ilustra cuatro g^neros y cuatro 
especies de Taiwan. Survakanta ( 1973) estudia 47 g^neros y 84 especies y menciona 
que la evoluci6n de las aberturas del polen proviene de un colpo espiraperturado, 
ademds indica que las Bignoniaceae que crecen como lianas presentan mas \ anaciones 
en el polen que las arbustivas o Irboles y que los g^neros herbaceos se caracienzan por 
tener un gran niimero de aberturas. Buurman ( 1977) estudia las especies incolporadas 
en 83 generos de la familia Bignoniaceae. Markgraf & D'Anioni ( 1978) observan e 
ilusU"an el de tres generos y tres especies de la Argentina. Gentry & Tomb ( 1979) 
estudian el pc:)len de 63 taxa al microscopio electronico de bamdo y mencionan 26 



10 PHYTOLOGIA January 1996 volume 80(1) :8-22 



tipos polfnicos para la familia, relacionan la morfologia del polen con la taxonomi'a de 
la familia y las Ifneas evolutivas que han propuesto otros autores. Femandes-Silvestre 
& Melhem (1989) descnben e ilustran al microscopio de luz y de bamdo diesmueve 
g^neros del parque estatal das Pontes do Opiranga en Sao Paulo, Brasil. Roubick & 
Moreno (1991) descnben e ilustran veinte g^neros y 31 especies de la Isla Barro 
Colorado, Panami Palacios-Chdvez et al. (1991) para la flora de la reserva de Sian 
Ka'an, Quintana Roo, Mexico descnben e ilustran seis g^neros y ocho especies. Bove 
(1993) estudia al microscopio de luz y de bamdo la morfologia de diesinueve generos 
y 33 esp>ecies de Bignoniaceae nativas del sur de Brasil. 



METODOLOGIA 



Las muestras de polen fueron tomadas principalmente de los ejemplares de 
herbano depositados en el museo de la Estaci6n de Biologia Chamela, Jalisco y del 
Herbario del Institute de Biologia de la Universidad Nacional Aut6noma de Mdxico 
(MEXU). Cuando no se pudo tomar polen de esa colecci6n, por carecer de flores, las 
muestras polfnicas se obtuvieron de ejemplares colectados en diversos lugares de la 
Republica Mexicana previa corroboraci6n de la identificaci6n de los mismos como fue 
el caso de Arrabidaea patellifera, cuyo polen se tomo del ejemplar depositado en el

CONCLUSIONES 



La familia Bignoniaceae es euripalinol6gica, y al comparar la morfologi'a del polen 
con las subdivisiones taxonomicas realizadas por Schumann (1895), y Gentry & 
Tomb (1979), encontramos que estos autores separan a la familia en las siguientes 
tnbus: 

BIGNONIEAE: Arrabidaea, Melloa, Xylophragma, Clysiosioma, Cydista, 
Adenocalymma, Pithecoctenium 

TECOMEAE: Tabebuia 

CRESCENTIEAE: Crescentia 

El genero Astianlhus no fue considerado en los sistemas de clasificacion 
mencionados. 

Al comparar las divisiones taxonomicas de la familia con la morfologi'a del polen 
en este trabajo encontramos lo siguiente: 

Arrabidaea corallina y A. viscida presentan polen tricolporado y perlenece a la 
tnbu Bignomeae. 

Melloa quadrivalvLS. Xylophragma seemannianum, Tabebuia chrysanlha, T. 
donnell-smithii, T. impetiginosa, T rosea, y Crescentia alata con pc:)len tncolpado, 
tncolporoidado a tncolporado, el pnmer genero con omameniacion escabrosa y los 
otros tres con omamentacion reticulada a perreticulada. Melloa y Xvlophragma 
pertenecen a la tnbu Bignomeae, Tabebuia a la Tecomeae y Crescentia a la tnbu 
Crescenlieae. 

Tabebuia se cita en la bibliograli'a con polen tncolpado a tetracc^lpado, sin 
embargo, en las especies estudiadas para la Estaci6n de Biologia Chamela, Jalisco 
encontramos que las aberturas vanan desde la tncolpada, tncolporoidada a tncolporada 
y tomando en consideracion las aberturas, el tamano del polen, y el lamano de los 
lumenes es factible la separaci6n de las especies. 



Airegufn-S^chez^/a/.: Bignoniaceae pollen morphology 21 



Clytostoma binatum. Cydista aequinoctialis, Pithecoctenium crucigerum, y 
Adenocalymma inundatum fsertenecen a la inbu Bignomeae, los tres pnmeros generos 
presentan polen inaperturado con liimenes de diferentes di^etros y el ultimo genero 
con polen equinado. 

Astianthus viminalis presenta polen tricolpado, psilado, diferente al polen de las 
otras Bignomaceae descntas para la Estaci6n de Biologi'a Chamela, Jalisco. 

Por todo lo antenor, se puede apreciar que no existe una relaci6n enu-e las 
divisiones taxon6micas y la morfologia del polen y posiblemente este taxa pueda 
pertenecer a otra subdivisi6n taxon6mica no considerada por autores como Schumann 
( 1895) y Gentry & Tomb ( 1979). 

En el caso de los taxa estudiados para la estaci6n de Biologi'a Chamela, Jalisco, es 
factible separar casi todos los taxa por medios palinol6gicos tomando en consideracion 
el tipo de aberturas que se presentan, la omamentaci6n, tamaiio, forma del polen y el 
indice del Irea polar. 

Cydista diversifolia fue descnto al microscopio electr6nico de bamdo por Gentry 
& Tomb (1979) como pencolpado, sin embargo, el polen de los ejemplares de 
Chamela, Jalisco se observan inaperturados al microscopio de luz. Asi' tambien, estos 
mismos autores indican que Cydista aequinoctialis presenta la mayon'a de los granos 
de polen como inaperturados con reticulo medio, aunque tambidn presentan granos 
pencolpados. El ejemplar de Chamela Jalisco, presenta polen inaperturado.

IDENTIFICATION AND DISTRIBUTION OF CENTAURIUM MUHLENBERGII 

(GRISEB.) PIPER AND C. PULCHELLUM (SW.) DRUCE 

(GENTIANACEAE) IN LOUISIANA, MISSISSIPPI, AND TEXAS 



Walter C. Holmes & Daniel E. Wivagg 
Department of Biology, Baylor University, Waco, Texas 76798 -7388 U.S.A. 

ABSTRACT 



Cenlaurium muhlenbergii is reported as new to Louisiana, Mississippi, and 
Texas. The species is compared with and distinguished from the apparently 
closely related C. pulchellum. A key to the two species, a list of specimens 
examined, and a distnbution map are also included. Three other Cenlaurium 
sfsecies mentioned as occumng in Louisiana are also discussed. 

KEY WORDS: Gentianaceae, Cenlaurium, Louisiana, Mississippi, Texas 



Cenlaurium is a taxonomically difficult genus of about 60 species of Old and New 
World distnbution. Two species that occur in the United States, Cenlaurium 
muhlenbergii (Gnseb.) Piper, a native, and C. pulchellum (Sw.) Druce, an e.xouc 
from Europe, bear close resemblance to each other. Both are annuals, lack rosettes or 
may have weakly developed ones, and possess small flowers with corolla lobes 2-5 
mm long. The similarity of the two sfjecies, coupled with their previous mutually 
exclusive distnbutions in the United States (which hinders direct field companson), 
have resulted in taxonomic uncertainty concerning the correct status of the plants. 
Prior to this study, C. muhlenbergii was known from central Washington south to 
central California, western Nevada, and Idaho (Cronquist et al. 1983). Cenlaurium 
pulchellum is widely distributed in eastern United States (Femald 1950; Small 1933). 
Both Cronquist el al. (1983) and Hickman (1993) consider C. floribundum (Benth.) 
Robinson to be synonymous with C. muhlenbergii and further suggest that the latter 
name may well be reduced to synonymy under C. pulchellum. The present paper is 
intended to clanfy the status of C. muhlenbergii and C. pulchellum, and document 
their distnbution in the states treated. Additionally, reports of C. calycosum (Buckl.) 
Fern., C. erythraea Raf.. and C. lexense (Gnseb.) Fern, in Louisiana will be 
evaluated.

The study is based upon field observations and collections of both species and 
examination of herbarium specimens or photostatic copies of specimens from ASTC, 
BAYLU. BRIT, IBE, LAF, LSU. LSUS. LTU, NLU. and TAES. 

While Centaurium muhlenbergii and C. pulchellum have overall similanty, 
especially flower and leaf characteristics, there are substantial differences (Table 1) 
that evidence the distinctness of each. One item in the table requires further 
explanation. Whether a flower is sessile or pedicelled is determined by the location of 
the epicalyx, the two bracts subtending the calyx. In pedicelled flowers, the epicalyx 
is slightly separated from the calyx, while in sessile flowers the calyx is immediately 
subtended by the epicalyx. This trait is more apparent on the lateral flowers of the 
ultimate cymes. 

Although the plants may be distinguished by use of the table, the following key, 
adapted in part from Hickman (1993), provides for accurate and easy distinction 
between the two plants. 



1. Flowers essentially sessile; inflorescence umbellate-cymose, dense, flat topped; 

plant normally branching in the upper one-third to one-fourth C. muhlenbergii 

1. Flowers pedicelled; inflorescence an open compound dichasium, not flat topped; 

plant normally branching in the lower one-half C. pulchellum 



This IS the first report of Centaurium muhlenbergii (which includes the 
synonymous C. floribundum) in Louisiana, Mississippi, and Texas. The size oi the 



26 PHYTOLOGIA January 1996 volume 80(1 ):23-29 



plant (up to 55 cm), dense clusters of bright pink flowers, colonial nature, and mainly 
roadside occurrence make the species very easy to locate, thus suggesung it to be a 
rather recent arrival. This is supported by the earliest known Texas sf)ecimen 
[Amerson 510 (BRIT)] being collected in 1971 and the earliest located Louisiana 
specimen [Thieret 26682 (LAF)] being collected in 1968, but both being misidenufied 
as either C. pulchellum or C. lexense. The only Mississippi record was collected in 
1989. Figure I shows the documented distnbution of the species in the three states.

Centaurium pulchellum has long been known to occur in Louisiana and 
Mississippi (Small 1933). Unfortunately, we have not had access to any specimens 
from Mississippi, thus further comment is not possible. The species was first 
reported in Texas by Correll & Johnston ( 1972). Turner (1993), in a treatment of the 
genus for Texas, provided documentation of the species in Hardin and Brazona 
counties. Figure 1 depicts the distnbution of the species in Louisiana and Texas. The 
plant is often misidentified as C. texense.

Further comment on Ceniaurium in Texas is not needed since Turner (1993) 
provided an accurate account of the species in the state and, as mentioned, is not 
possible for Mississippi because of the lack of specimens. Several other species of 
Centaurium, however, have been reported in Louisiana. With clarification of the 
status of C. pulchellum and C. muhlenbergii, it is now possible lo comment on these 
reports. 

Centaurium calycosum (Buckl.) Fern, was reported by MacRoberts (1987) as 
occurring in DeSoto Pcirish, based upon Gilmore 1833 (LTU). Turner (1993) gives 
the distribution of C. calycosum as being primarily in the western portions of the 
Edwards Plateau of Texas, and several adjacent areas, such as Mexico. It is reported 
by Cronquist et al. (1983) as occumng in New Mexico, Arizona, Utah, etc. Upon 
examination, Gilmore 1833 proved to be C. muhlenbergii collected near Coushatta in 
Red River Parish. 

MacRoberts (1987) also reported Centaurium erythraea Raf. from Caddo Parish, 
citing MacRoberts 550, 923, 1201, & 2688 (all LSUS). This species is an European 
native that has become naturalized from northern coastal California to Washington 
(Hickman 1993). The plant is similar to C. muhlenbergii in appearance but is a 
biennial with a conspicuous basal rosette and has corolla lobes 5-7 mm long. 
Examination of clear photocopies of these specimens showed they lacked basal 
rosettes and appeared to be annuals. They are thus referable to C. muhlenbergii. 

Centaurium texense (Griseb.) Fern, was reported from Rapides and Calcasieu 
parishes by Thieret (1968). The distnbution of this species includes the eastern edge 
of the Balcones Escarpment of Texas, eastern Oklahoma, northwestern Arkansas, and 
southwestern Missouri. The plant is limited to dry, limestone denved soils and eroded 
limestone slopes, glades, and roadcuts, all non-existent in Louisiana. The specimens 
cited by Thieret (1968). Thieret 26682 and 28829 (both LAF) proved to be C. 
muhlenbergii and C. pulchellum respectively.

ABSTRACT 

Phyllostachys aurea is shown to be widely distnbuted in the eastern part of 
Texas. 

KEY WORDS: Gramineae, Phyllostachys, Texas 



Phyllostachys aurea Riv., commonly called yellow bamboo, is a native of Chma 
that was mtroduced into the southern United States prior to 1870 (Rehder 1986) as an 
ornamental, barrier planting, or for soil stabilization and erosion control. The plant is 
a vigorous colonizer and readily escapes containment or is commonly abandoned. The 
size of some colonies, sometimes over 100 m in length, indicates that the species, once 
established, can persist for extended penods of time. The species may grow to 6 m 
tall and forms dense stands, often to the exclusion of other vegetation. The genus 
Phyllostachys is characterized by the culms being flattened on one side above each 
node, a trait useful in distinguishing it from the native Arundinaria gigantea (Walt.) 
Muhl. Additional traits of Phyllostachys aurea are its yellow stems, leaf sheathes 
generally without spots but with two tufts of bnstles at the apices, and presence of 2-3 
linear leaves 5-12 cm long and 1-2 cm wide at the tip of each branch. Additional 
information can be found in Allen ( 1992). 

The plant is included as part of the naturalized flora of Louisiana by Allen ( 1992) 
and by Thomas & Allen (1993). It is also present in Mississippi (pers. comm. with 
Sidney McDaniel of IBE). Gould (1975) did not include Phyllostachys in his 
treatment of the grasses of Texas nor was it included in the latest checklist of the

vascular plants of the state (Hatch ei al. 1990). Its widespread occurrence in Texas 
(Figure 1), spread to areas where it seems not to have been intentionally planted, and 
persistence, warrants its inclusion as part of the namralized flora of Texas. 

Jenzan (1976) gives the intermast period of Phyllostachys aurea as 28-29 (2x 14- 
15) years, a figure based on observations of plants introduced to [mainland] Europe 
and England. He mentions that the time penod is more fixed in the center of the 
natural distnbution of a species and synchrony may be lost under cultivation or if the 
plants are feral, thus the Texas plants may not follow this schedule. He suggests the 
long interval between flowenng evolved to escape seed predation. At this time, no 
fertile matenals are known from Texas.

ABSTRACT 

The following nomenclatural combinations in the Poaceae are proposed: 
Schizachyrium spadiceum (J. Swallen) comb. nov.; and 
Schizachyrium scoparium (A. Michaux) G. Nash var. stoloniferum (G. 
Nash) comb, et stat. nov.

Schizachyrium spadiceum (J. Swallen) J. Wipff, comb. nov. BASIONYM: 
Andropogon spadiceus J. Swallen, Proceedings of the Biological Society of 
Washington 56:82 (1943). TYPE MEXICO. Coahuila; Canon de Madera, 
western side of Sierra de los Guajes, about 4 km east of Rancho Buena Vista, 7 
Sept 1941, Robert M. Stewart 1504 (HOLOTYPE: US, accession #154691). 

Schizachyrium spadiceum, restricted to Coahuila, Mexico and Brewster County, 
Texas, is the first reported species oi Schizachyrium with a panicle of paired branches. 
All of the other reported speaes of Schizachyrium have spicate racemes. This should 
not be surprising since there are species of Andropogon that have spicaie racemes 
(e.g., A. textilis A. Rendle, A. fastigiatus O. Swartz, and A. gracilis K. Sprengel), 
and there are also species that may have either spicate racemes or panicles of paired 
branches (e.g., A. urbanianus A. Hitchcock, A. reedii A. Hitchcock & E. Ekman, and 
A. kelleri E. Hackel). It appears that too much significance has been placed on the 
condition of spicate racemes vs. panicles of pnmary branches; more reliable characters 
can be found in the lower glume of the sessile spikelet, the intemodes of the central 
axis, and the pedicels (Clayton 1964). Clayton ( 1964) pointed out that the significance 
attached to spicate racemes probably arose from the value of this character in 
segregating Schizachyrium Nees von Esenbeck. Excluding the parucles of paired 
branches, S. spadiceum possesses all of the below mentioned genenc characters that 

35 



36 PHYTOLOGIA January 1996 volume 80( l):35-39 



are used to delimit Schizachyrium from Andropogon and justify its placement into 
Schizachyrium. 

Schizachyrium is most closely related to Andropogon sect. Leptopogon (Clayton 
1964; Clayton & Renvoize 1986). Clayton (1964) and Clayton & Renvoize (1986) 
provided the following characters to delimit Schizachyrium and Andropogon sect. 
Leptopogon, with the inflorescence character being amended to accommodate 
Schizachyrium spadiceum. 

Schizachyrium: Inflorescence a spicate raceme or panicle of paired branches (i.e., 
5. spadiceum); first glume of sessile spikelet convex on the back with several 
intercannal veins; intemodes and pedicels clavale to linear (but then often widening at 
the tip); the apex of the intemode usually conspicuously cup-shaped with a fimbnate 
nm; upper lemma bilobed or deeply cleft almost to the base. 

Andropogon sect. Leptopogon: Inflorescence a panicle of 2-several digitate 
branches or a spicate raceme (e.g., A. gracilis K. Sprengel); first glume concave; 
intercannal area membranous, hyaline or translucent, and veinless between the keels, 
or rarely with 1-2 veins in the translucent or hyaline, concave, intercannal area [e.g., 
A. tenarius A. Michaux (vanable, veins present or absent)]; intemodes and pedicels 
linear to filiform; the apex of the intemode shallowly cup-shaped; upper lemma bifid 
up to 1/4 of its length, very rarely more, but never beyond the middle. 

The following description of Schizachyrium spadiceum has been expanded from 
Swallen(1943). 

Plants perennial, 60-95 cm tall, cespitose, without rhizomes or stolons, culm 
erect, terete, glabrous. Leaves glaucous. Sheaths compressed, keeled, scaberulous 
(glabrous), occasionally with a few scattered tnchomes; the lower sheaths longer than 
the intemodes emd the upper shorter than the intemodes. Ligule 1.0-1.5 mm long, a 
membrane, truncate, erose-ciliate. Blade 10-25 cm long, 2.0-2.5 mm wide, flat or 
folded, scaberulous, young blades ciliate in lower portion with tnchomes 4-7 mm 
long, these often being lost in age. Inflorescence a panicle of paired branches, 
branches 3.5-6.0 cm long, 7-10 nodes; inflorescence exserted or partially enclosed in 
sheath; sheath (subtending inflorescence) 5.3-8.6 cm long; blade 0.5-39.5 mm long; 
peduncle 4.6-9.0 cm long. Internode (of inflorescence branch) 4.0-6.3 mm long; 
linear becoming wider, slightly swollen, at the af)ex; apex conspicuously cup>-shaf)ed 
with a fimbnate nm; lower 1/3-1/2 of intemode and pedicel ciliate, but upper portion, 
abaxially, densely white villous with tnchomes 4-7 mm long; intemodes straight, 
without a membranous, hyaline or translucent, median groove. Sessile spikelet 7-8 
mm long, golden to chestnut brown and the apex usually green; callus of white 
tnchomes to 2 mm long. First glume 7-8 mm long; 7-11 veins, (4-)5-7 equidistant 
intercannal veins, green; coriaceous, dorsally compressed, two-keeled, back of glume 
convex, glabrous, smooth, scaberulous on keels and veins in the upp)er portion; 
margins variously ciliolate. Second glume 6.5-7.0 mm long, 3- veined (lateral veins 
obscure, sometimes only faintly visible in the upper 1/2); subconaceous, laterally 
compressed, enclosing fiorets; glabrous except for ciliolate margins and scabemlous 
mid-vein at afjex. First lemma 4.8-5.8 mm long, veinless, hyaline membrane; 
glabrous, margins ciliolate; awnless; neuter. Second lemma 4.1-5.0 mm long, 3- 
veined; veined portion of lemma, in the center, chartaceous and the rest of the lemma a 
hyaline membrane, margins vanously ciliolate; apex cleft 1/3- 1/2 of lemma, teeth 1.7- 



WiplT: New combinations m Schizachyrium 37 



2.3 mm long, awned between cleft, awn 14.2-17.2 mm long, once geniculate, tightly 
twisted below the bend, lower segment 5-6 mm long, terminai segment straight, 8.7- 
11.2 mm long. Second palea 1.7-2.0 mm long, veinless; hyaline membrane, 
margins ciliolate. Anther 1.9-2.3 mm long; 3 stamens. Caryopsis 2.6-3.2 mm 
long, 0.70-0.75 mm wide; dark reddish purple. Pediceiled spikelet 0.8-4.0 mm 
long, neuter, greatly reduced, with only a first glume developed, awnless; pedicel 5- 
6 mm long; basal callus of tnchomes to 2 mm long; lower 1/3-1/2 (2/3) ciliaie, upper 
portion, aba.\j£illy, densely white villous with tnchomes 4-7 mm long; without a 
membranous, hyaline or translucent, median groove. Chromosome number 
unknown. 

Johnston (1981) commented that in the field Schizachyrium spadiceum has a 
strong superficial resemblance to Schizachyrium scoparium (A. Michaux) G. Nash.

Chase (1951) reported that Schizachyrium stoloniferum resembled S. scoparium 
and from examining her descriptions of the two ta:>;a the only significant difference 
between the two taxa was the presence of creeping scaly rhizomes in S. stoloniferum. 
In a systematic study of the S. scoparium complex, Bruner (1987) concluded that 5. 
stoloniferum was conspecific with S. scoparium and should be recognized at the 
varietal level. However, he also considered Andropogon scoparius A. Michaux var. 
polycladus F. Lamson-Scnbner & C. Ball as conspecific with S. stoloniferum and 
proposed a new combination: S. scoparium var. polycladus (F. Lamson-Scnbner & 
C. Ball) J. Bruner, ined. and treated 5. stoloniferum as a synonym. However, this 
new combination was validly published by Real (1987), but it was probably in the 
sense of Femald (1950) and not including S. stoloniferum, because the combin?tions 
in Reed ( 1987) were made in preparation for the Flora of Central Eastern United States 
(Maryland, Delaware, Virginia, and West Virginia) and S. stoloniferum is restricted to 
Flonda, and southern Georgia and Alabama. 

Bruner (1987) treated, without any specific explanation, Andropogon scoparius 
var. polycladus as conspecific with Schizachyrium stoloniferum, whereas Nash 
(1912), Hitchcock (1935), Chase (1951), and Gandhi (1989) treated var. polycladus 
as a synonym of Schizachyrium (Andropogon) scoparium {= Schizachyrium 
scoparium \m. scoparium). Nash (1912), Hitchcock (1935), Femald (1950), Chase 
(1951), and Gandhi (1989) charactenzed var. polycladus as non-rhizomatous, 
whereas Bruner (1987) considered it rhizomatous. After examining photographs of 
the type specimens of var. polycladus and S. stoloniferum I agree with Gandhi ( 1989) 
that the type specimen of var. polycladus does not possess rhizomes, whereas the i\pe 



38 PHYTOLOGIA January 1996 volume 80(l):35-39 



of 5. stoloniferum does have rhizomes. Lamson-Scnbner & Ball (1901) m their 
original description of var. polycladus never mention this taxon as having rhizomes. 
The following is the original description by Lamson-Scnbner & Ball (1901) for var. 
polycladus: "Stout, 9 to 12 dm. high, glabrous, somewhat glaucous; panicles large, 
much branched". 

Another difference between Bruner (1987), and Lamson-Scribner & Ball (1901), 
Nash (1912), Hitchcock (1935), Femald (1950), Chase (1951), and Gandhi (1989), 
is in the reported distributions of these taxa Bruner (1987) commented that 
Schizachyrium stoloniferum is ". . . ecologically restricted to specific habitats in the 
southeastern United States and spatially isolated from the rest of S. scoparium, . . .". 
Bruner reports the distribution of 5. stoloniferum (including var. polycladus) as 
occurring throughout Rorida, and southern Georgia and Alabama, on the sandy soils 
of woodlzmd opjenings and roadsides. However, he does not report S. scoparium var. 
scoparium as occurring in Honda. Therefore, if S. scoparium var. scoparium is not 
recognized as occurring in Florida, and since the type for var. polycladus was 
collected in Manatee County, Florida, it is understandable why Bruner treated this 
taxon as conspecific with S. stoloniferum. Nash (1912), Hitchcock (1935), Femald 
(1950), Chase (1951), and Gandhi (1989) all report S. scoparium {= var. scoparium) 
as occurring in Florida. Bruner (1987) not only reports different distributions for S . 
scoparium var. scoparium, but also greatly restricts the distnbuuon of var. polycladus 
from what has been reported. 

Femald (1950), recognizing var. polycladus as a distncl \ariety of Andropogon 
scoparius, reported its distribution as occurring in dry woods from Texas to Flonda 
and Mexico, north to New Jersey through eastem Missoun and Pennsylvania. 
Lamson-Scribner & Ball (1901) give the following additional distnbutions for var. 
polycladus, 'Tracy's No. 5330, from Biloxi, Mississippi, and a plant collected by 
John K. Small on the slopes and summit of Stone Mountain, Georgia, September 6- 
12, 1894, belong here." Stone Mountain is a granite dome located in northwestern 
Georgia, east of Atlanta. 

No data were found supporting the treatment of Andropogon scoparius var. 
polycladus and Schizachyrium stoloniferum as conspecific (Bruner 1987), therefore I 
am treating var. polycladus as a synonym of S. scoparium var. scoparium as did Nash 
(1912), Hitchcock (1935), Chase (1951), and Gandhi (1989). However, I do not 
agree with Gandhi (1989) in the placement of S. stoloniferum as a synonym of S . 
scoparium var. littorale (G. Nash) F. Gould. 

Schizachyrium scoparium var. stoloniferum and S. scoparium var. littorale occupy 
different habitats and have different growth habits. Schizachyrium scoparium var. 
stoloniferum is found in sandy woodlands and roadsides, whereas S. scoparium var. 
littorale grows on the shifting, coastal sands. Schizachyrium scoparium var. 
stoloniferum is strongly rhizomatous, whereas, S. scoparium var. littorale, as Bruner 
( 1987) also reported, is not rhizomatous. Schizachyrium scoparium var. littorale only 
appears rhizomatous due to the continual bunal of the culms and the subsequent decay 
of the sheath and blades from the culms. This results in the buned culms superficially 
resembling rhizomes. It is my opinion that S. scoparium var. littorale and S . 
scoparium var. stoloniferum represent two different and recognizable taxa.

Oreocereo leucotrichi-Neoraimondietalia arequipensis ordo novo, 
Corryocaction brevistyli alUanza nova, Corryocacto aurei- 
Browningietum candelaris associatio nova, and Oreocereo

INTRODUCCION 



El Peru es uno de los paises de Am^nca con mayor diversidad de cactaceas. Sus 
representantes se encuentran distnbuidos p)or todo el pais aunque la mayor

Galdn de Mera & Vicenle-Orellana: Comunidades con Corryocactus 41 

concentraci6n aparece en las vertienles dndas occidentales de los Andes, entre 1000 y 
3000 m de altilud [T= 15-20''C, P= 30-70 mm] (Rauh 1979). 

Al parecer, en la costa y Andes del norte del Peru, se encuentran en mayor 
proporci6n los elementos mds antiguos de la vegetacion peruana (Solbng 1976)- 
Acacia. Bulnesia, Loxoplerygium, Prosopis {. . .)- que ademds, muchos de ellos, son 
los que aparecen en la sabana chaquena (al S de la Cuenca Amaz6nica), como por 
ejempio, Cercidium praecox, Geojfroea decorticans, Parkinsonia aculeata, y Prosopis 
pallida (Cdrdenas 1945; Bemardi 1984). La presencia de algunas de estas plantas en 
los valles des^rticos e mterandinos del centro y sur del Perii (Fortaleza, lea, Juni'n, 
Nazca, y Tacna) demuestra la existencia de una vegetacion de tipo chaqueno en los 
pnmeros periodos de la formacion de los Andes. El levantamiento de la cordillera y la 
intensificaci6n de la comente de Humboldt durante el Pleistoceno, ongm6 una gran 
zona Inda con elevada canUdad de endemismos al W de los Andes (Miiller 1985; 
Galan de Mera^/ al. 1995). En la TaWa 1 mostramos el alto niimero de endemismos 
inventanados en las laderas dndas occidentales del Peru. Adem^, podemos observar 
c6mo los grupos de plantas B y C son caractensticos de las formaciones vegetales del 
norte (La Libertad, Lambayeque, F*iura, y Tumbes), mientras que otras sabaneras 
como Cercidium praecox (A) se encuentran como reliquias en temtonos del centro del 
Peni (lea). Tambi^n en la Tabia 1 nos encontramos con un gran paquete de cactaceas 
end^micas que delatan asociaciones fitosocioldgicas claramente definidas.

Browningia cande laris {V^cherbauev 1912, 1945; Rauh 1958, 1979; Ferreyra 1987). 
Sm embargo, nosotros seguiremos el metodo fitosocioldgico de Braun-Blanquet 
(1964) ya que permite profundizar en el andlisis y clasificacion de los ecosisiemas y 
ademds establecer una comparaci6n ecol6gica, dinlmica y geogrlfica con otras 
estructuras disyuntas (Moravec 1992).

+ Orden Oreocereo leucotrichi-Neoraimondietalia arequipensis ordo novo 
Typus: Corryocaction brevistyli allianza nova 

Es el orden de las comunidades de cardonales andinos neotropieales. 

Plantas caractensticas: Armatocereus matiicanensis, Carica candicans, 
Cnidoscolus basiacanthus, Jatropha macrantha, Melocactus peruvianus, Neoraimondia 
arequipensis, Oreocereus leucotrichus, y Orthopterygium huaucui. 

Las especies de eact^ceas que proponemos como caracten'stieas del orden son las 
que tienen una mayor distribuei6n en los Andes occidentales del Peru (Rauh, 1958; 
Ritter 1981; Zarueehi 1993). Oreocereus leucotrichus se encuentra en Bolivia, Chile, 
y Peru con una distnbuci6n bastante amplia, al menos alutudinalmenle (2000 a 4(X)0 
m) [Ritter 1981; Hunt 1992]. Tambi^n incluimos entre las earacterisucas a algunos 
drboles y arbustos end^micos (McBnde 1937, 1941, 1951; Brako 1993). 

* Alianza Corryocaction brevistyli allianza nova 

Typus: Oreocereo tacnaensis-Corryocactetum brevistyli associatio nova 

Corryocactus brevistylus es una planta cuyo areal se extiende desde Arequipa 
(Peru) hasta Mamina (Chile), y esti presente tanto en el piso de Browningia candelaris 
(2000-3000 m) como en el nivel altitudinal siguiente, hasta 35(X) m. En este ultimo 
espacio convive con otras plantas propias de la puna seea peruano-chileno-boliviana, 
como Diplostephium meyenii o Parastrephia lepidophylla. La alianza Corryocaction 
brevistyli agrup>a, por tanto tambi^n, a plantas earacterisucas que uenen una 
distribuci6n latitudinal semejante a Corryocactus brevistylus en el S del Peni y N de 



GaJdn de Mera & Vicente-Orellana; Comunidades con Corryocactus 45 



Chile (Hoffmann 1989): Ambrosia artemisioides. Browningia candeUiris. Oreocereus 
hempelianus. Sin embargo, altitudinaJmente, la dividimos por el momento en dos 
asociaciones: 1- Corryocacto aurei-Browningietum candelaris y 2- Oreocereo 
tacnaensLs-Corryocactetum brevistyti. 



1- Corryocacto aurei-Browningietum candelaris associalio nova Typus: 
inventano 8, labia 2. 

Comunidades muy dispersas de cacticeas (5-10% de cobertura) cuya especie 
directriz es Browningia candelaris. Se Irata de una biocenosis que se asienta sobre las 
laderas de derrubios cuarcfticos de los Andes occidentales, entre 2000 y 3(XX) m de 
altitud, y se extiende entre los depariamentos de Arequipa y Tacna. 

Caracteristicas: Browningia candelaris, Corryocactus aureus, y Haageocereus 
plaiinospinus. 



2- Oreocereo tacnaensis-Corryocactetum brevistyti associalio nova Typus: 
inventano 9, tabia 2. 

. Al contrario que la asociaci6n antenor, se trata de una comunidad bastante mas 
densa (50-60% de cobertura) debido a la entrada de elementos de la puna seca, causada 
por un aumento de las precipitaciones, y a los sustratos mas compactos. 
Altitudinalmente tiene su optimo entre 3000 y 3500 m. Hasta el momento, 
restnngimos su areal a los Andes del departamento de Tacna en funcidn de la 
distribuci6n de su especie diferencial, Oreocereus tacnaensLs (Ritter 1981).

ABSTRACT 

The Academies of Sciences of the new republics organized from the former 
Soviet Union (USSR) are reviewed for their current status and discipline 
interests. Some of the largest and oldest academic institutes in the world are 
found within the former USSR framework. These institutes include research 
laboratories, herbaria, and agricultural centers representing disciplines of the 
plant sciences. New institutes organized since the dissolution of the USSR are 
also included. Names of noted scientists are incorporated into the titles of 
some of these academic centers. All areas of science and engineenng, 
including the botanical sciences, are briefly presented in this review of the 
Commonwealth of Independent States (CIS) Academies as they now exist. 

KEY WORDS: USSR-CIS Academies of Sciences, laboratones, institutes, 
research centers, academic disciplines of the Academies, the Ukraine Academy 



Since the recent formation of the independent republics, created out of the former 
Soviet Union, the Academies of Sciences facilities within each republic have conunued 
to function independently. Laboratones, insututes, and research centers produce 
research projects with quality data from in-depth studies. Many thousands of 
professional and highly trained individuals are employed in these facilities. The 
majority of their findings are presented as journal articles, reports, lectures, and 
symposia within their institutes. Good working relations e.xist between the Soviet 
Aaidemies and European based science organizations, particularly in Finland, 
Germany, and England. Academies are now organized within separate republics, 
utilizing the previous Soviet Union adminisu-ative and scienufic personnel. Since the 
formation of the republics, the Academies have actually expanded their operations and 
academic disciplines. There is also a newly organized Russian Academy of Sciences

housed in new Moscow facilities intended tor use by the entire former USSR 
Academies of Sciences (Figure 1). IndividuaJ Academies are examined according to 
their research specialties in the new republics with emphasis given to the detailed 
structure of the Academy of Sciences of the Ukraine. 

Prior to the formation of the independent republics, the headquarters for all 
institutes, sections, and labt)ratones of the Academy of Sciences of the Soviet Union 
was Moscow. One Academy existed with many individual and corresponding 
members located throughout the previous Soviet Union. The central offices for the 
Soviet Union were housed in the former palace and support building used by 
Napoleon on his march through central Europe (Figure 2). A new Academy building 
was constructed in Moscow to house the central offices of the ever expanding 
institutes and research facilities of the Soviet Union (Figure 3). This building brings 
to the Moscow skyline an ultra modem multisection structure of an architectural design 
unique to Moscow (Figure 4). Completed just before the Soviet dissolution, the new 
building complex was constructed near the Yuri Alekseyevich Gagann Memorial and 
the Gagann Plaza. With the dissolution of the Soviet Union, the new building now is 
headquarters for the reorganized Russian Academy of Sciences. Also included in the 
building are conference rooms, reception halls, and auditonums in addition to 
administrative office suites for science, cultural, and engineenng disciplines. 

. Now the republics have independent Academies of Sciences and corresponding 
administrative offices. The independent Academies of Sciences and capital cities 
include the Academies of Azerbaijan (Baku), Annenia (Yerevan), Belarus (Minsk), 
Estonia (Tallinn), Georgia (Tbilisi), Kazakhstan (Alma-Ata), Krgyzstan (Bishkek), 
Latvia (Riga), Lithuania (Vilnius), Moldova (Kishinyov), Russia (Moscow), 
Tajikistan (Dushanbe), Turkmenistan (Ashkhabad), Uzbekistan (Tashkent), and the 
Far East and Ural Scientific Center Section in addition to the Ukraine (Kiev). 

The Academy of Sciences of Azerbaijan was founded in the capital city Baku in 
1945 on the basis of the Azerbaijan Branch of the Academy of Sciences of the USSR. 
The Academy has 47 full members and 46 corresponding members that compnse the 
voting personnel found in five sections and 30 scientific establishments and facilities. 
Noted areas of specialization include mathematics, hydrodynamics, physics of semi- 
conductors, electrophysics, the chemistry of oil, geology, physiology, biochemistry, 
and other closely related fields, with the biological sciences receiving less attention. 

The Academy of Sciences of Annenia was founded in 1943 in Yerevan. 
Individual membership includes 40 members with 50 corresponding members and 
three foreign members in six sections and 30 scientific establishments. Noted 
scientific disciplines include mathematics, cybernetics, astrophysics, mechanics of 
solid bodies, geology, seismology, the chemistry of natural and synthetic compounds, 
biochemistry, and archaeology. 

The Academy of Sciences of Belarus with headquarters in Minsk was organized in 
1928 on the basis of the Belarus culture. The organization was initiated with nine 
research insututes and three independent labs. After World War 11 (the Great Patriotic 
War), many scientific enterpnses were developed and incorporated into the Academy. 
There are approximately 53 members, 75 corresponding members in five branches and 
32 scientific establishments. Scienufic disciplines of particular note include solid 
physics, high temperature optics physics, nuclear engineenng, computer devices. 



50 PHYTOLOGIA January 1996 volume 80( l):48-57 

cybernetics, radiobiology and photosynthesis, economics, philosophy, and 
linguistics. 

The Academy of Sciences of Estonia was founded in 1946, aiter the Great 
Patriotic War. The Academy has 21 members, 24 corresponding members, and ten 
research establishments. The complex use of slate fuel is a major research discipline 
of study. 

In the city of Tbilisi, the Academy of Sciences of Georgia was founded in 1941. 
There are 63 academy members, 69 corresponding members in nine sections and 41 
scientific establishments. Over 1000 scientific topics and 234 science problems are 
under study. 

The city of Alma-Ata was the founding location for the Academy of Sciences of 
Kazakhstan in 1946. There are 53 members of the Academy, 85 corresponding 
members with five br«mches, 42 research establishments, and sixteen institutes. With 
a staff of over 1800 members, 48 hold Ph.D. degrees, 238 M.S. degrees, 200 
assistants, and over 200 are graduates of the institutes. 

In Bishkek the Academy of Sciences of Kyrgyzstan was organized in 1954. A 
total of 26 members and 32 corresponding members form the entire membership. 
Five sections and seventeen scientific establishments are found in the Kyrgyzstan 
Academy. Trends of study in the Academy include developmental geology, physics, 
and geochemistry of mountain rocks. 

The Academy of Sciences of Latvia was organized in Riga in 1946. The Latvia 
Academy has 25 academy members and 31 corresponding members. There are three 
sections and fifteen scientific establishments. The guidelines of the Academy examine 
the national economy and the culture of the republic. 

The Academy of Sciences of Lithuania was founded in Vilnius in 1941, and 
restored in 1946. The Academy now has 23 members and 25 corresponding members 
in three branches and twelve scientific establishments. Research trends include 
theories of probabilities, statistics, problems of cybernetics, theoretical spectroscopy 
of atoms and molecules, physics of semi-conductors, high temperature heat physics, 
metal coatings, and galvanic covers with previously set properties. Biological 
pnnciples to increase plant growth along with economics are under study as are the 
disciplines of history, languages, and literature. 

The Academy of Sciences of Moldova was founded in 1961 in Kishinyov. The 
eighteen members and 26 corresponding members are found in three branches and 
seventeen scientific establishments. The pnmary research trends are directed to 
solving problems of agriculture to increase production. The history and culture of 
Moldova are also under study. 

The Academy of Sciences of Russia was reorganized in 1991. First founded in 
1917, then in 1925, the organization was expanded into the Academy of Sciences of 
the U.S.S.R. Before 1917, the group was known as the St. Petersburg Academy of 
Sciences which was initially founded in 1724. From 1934 to 1991 the Academy was 
housed in Moscow. There are approximately 269 members, 536 corresponding 
members, and 77 foreign members. 



Volz & Babutina; Reorganization of Soviet Academies of Science 51 



The U.S.S.R. Academy of Sciences had several sections. These sections included 
mathematics, general physics and astronomy, nuclear physics, physico- mechanical 
problems of mechanical engineering, mechanics and process of management, general 
and technical chemistry, physicochemistry and technology of inorganic matenals, 
biochemistry, biophysics, and chemistry of biologically acDve compounds, 
physiology, general biology, geology, geophysics and geochemistry, oceanology, 
physics of the atmosphere, geography, history, philosophy and law, economics, 
literature, and language. 

The Soviet complex included 250 scientific establishments, with about 42,000 
science workers, 200 scientific councils, and a research fleet. It coordinated the 
activities of the Academy of Sciences of the Union Republics. The complex trained 
the research staff. Included were 16,500 postgraduates located throughout the Union 
Republics. Under the Union Republics, organized through Moscow, the Union 
Academies awarded medals and pnzes for science works. Also coordinated through 
Moscow were a number of Science Societies within the Academy of Sciences of the 
former U.S.S.R. The Soviet Academy also handled scientific relations with 250 
international organizations located in many countnes. 

The Academy of Sciences of Tajikistan was organized in 1951 in Dushanbe. The 
disciplines and sections of the Academy include mathematics, seismology, 
astrophysics, nuclear physics, chemical technology, biology as well as history and 
literature. The number of members in Tajikistan is not known. 

The Academy of Sciences of Turkmenistan was organized in 1951 in Ashkhabad. 
Research specialties include molecular acoustics, spectroscopy, applied geophysics, 
petroleum chemistry, desert fcurning, cotton productivity, biochemistry of viruses as 
well as history of the area, languages, and literature. The number of members in 
Turkmenistan is not known. 

The Academy of Sciences of Uzbekistan was founded in 1932 in Tashkent on the 
basis of a republic committee guided by the Soviet science establishments. Regular 
meetings and the Academy structure were developed by 1940. The number of 
members in Uzbekistan is not known. In addition, the Sibenan section and the Far 
East and Ural Scientific Center contain eleven branches, including five in Sibena. 

The Academy of Sciences of the Ukraine was founded in 1918 by a group in Kiev 
headed by Academician Vemadsky who served as the first president. Succeeding 
presidents included Acad. Vasilenko ( 1921-22), Acad. Levitsky { 1922), Acad. Lipskv 
(1922-28), Acad. Zabolotny (1928-29), and Acad. Bogomoletz (1930-46). Frorn 
1946 to 1991 the Academy directorate was through offices in Moscow. Currently the 
Ukraine Academy has 83 Academy buildings or complexes, 87 organizations and 
departments, with 89,000 people working within the structure of the Academy. A 
total of 2096 people have earned their Ph.D. degrees, 10,336 have M.S. degrees, 
10,(X)3 people are professor - candidates of science, and 194 are academicians and 
269 corresponding members of the Academy of Sciences. Of the 2096 Ph.D.'s 2050 
work within the science establishments. Currently 54 foreign member belong to the 
Ukraine Academv.

The general management of the Ukraine Academy is structured for an office of the 
president, with a vice president, general science secretary, and assistant science 
secretary reporting to the president. The vice president's immediate staff includes a 
group manager, a special task group, a group for equipment computation and science 
instruments, and a group for plans, operations, and economics. In addition, special 
departments are designed lo report directly to the president and vice president. The 
special departments include the DepL of Science Organization, Dept. of Building, 
DepL of International Regulations, and the Dept. of Applied Programs. 

Major sections in the Ukraine Academy serve as the disciplinary areas of 
investigation and research. The areas of study evolved to fit the needs of the people 
and geographic location of the Ukraine. The research centers of the National Academy 
include the Innovation Center, Donetsk Research Center, West Research Center, 
South Research Center, North-Eastem Research Center, and the Research Center of 
the Dnieper Area. In comparing section topics between republics of the former Soviet 
Union, similarities are found when the Union was directed previously from Moscow. 
Additional disciplines identify the needs and requirements of a particular geographic 
location and more recently the requirements and ethnic background of a particular 
group of fjeople. Frequently these divisions are also separated by a particular 
language and cultural heritage. The Academy of Sciences of the Uloaine strongly 
reflects these regional and ethnic charactenstics and requirements. 

The central departments of the Ukraine Presidium include Metrology, 
Standardization, and Quality Production Control, with an Experimental Plant of the 
Institute of Superhard Materials. The Center of Research and Teaching Foreign 
Languages is becoming more widely used with the creation of the CIS. Departments 
include Material and Technical Supply, and Scientific Equipment. The extensive 
Natural Science Museum houses Archaeology, Geology, Paleontology, Zoology, and 
Botany Museums and herbana. The Science Exposition- Center, Science Exhibition 
Center, and Intertrade Firm help promote science information as does the Laboratory 
of Scientific Cinema - Photoinformation, House of Scientists, the Association of 
Young Scientists and Specialists, and individuals in their respective disaplines. 

Interdepartmental Research Councils in the Ukraine focus attention on 
Socioeconomic F*rognostication, Economics, Increase of Safety and Longevity of 
Machines and Structures, Corrosion and Anticorrosive Protection of Metals, and 
Problems of National Relations. Other Councils focus on Automation of Experimental 
Studies, Experimental Instrument Making, Problems of Biosphere, Philosophical and 
Social Problems of Science and Engineenng, Problems of Biotechnology, and the 
Automated Systems of Data and Computer Networks, Science F^iblications, Museum, 
Information - Library, and the Council on Mechanics and Technology of Explosion. 
Committees are organized for Slavonic Scholars, Studies and Expansion of Slavonic 
Cultures, the Program of UNESCO's Man and Biosphere, New and Regenerated 
Sources of Energy and Its Conservation, Chemical Problems, Scientific Terminology, 
Informatics, System Analysis, and the Committee of Science and Culture Relations 
with Ukrainians Abroad. Commissions include Space Research, TransjX)rt 
Development, Worid Oceans, Relations with the International Agency on Atomic 
Energy, Program on Goods and Services, Agricultural Sciences, Computer 
Engineering, Distribution and Use of Scientific Services and Installations,

Internationally recognized scholars are honorea by having their names attached to 
the various Institutes. A time of u-ansition is now underway with all Institutes under 
the former direction of central Academy control in Moscow. Now the Academy in 
Moscow is the directive for Russia, and Commonwealth States have independent 
junsdicuon for each new commonwealth republic. New associations replace the 
Soviet system, but as one nation dissolved into many, the entire fabnc of the new 
republics must be built that incorporates the traditions, customs, and languages of the 
regions of the former U.S.S.R. International Ucide is suddenly cnppled, and new 
economies and associations must be fostered. Cenual government funding, salaries, 
equipment, and supplies now are shifted to the private sector, international 
foundations, and associations. Dunng this transition, the Insuuites with their stall 
members remain available to supervise and guide the uansition to individual 
Commonwealth States, a stabilizing factor for nationality expression. Every 
procedure, new invention, method, and association is now a new experience in an 
entirely new set of values and in an entirely new way of life which has no 
infrastructure to replace the old Soviet system.

MAMMILLARIA LUETHYI (CACTACEAE), A NEW SPECIES FROM 
COAHUILA, MEXICO

ABSTRACT 

A new species of Mammillaria, M. luethyi G.S. Hinton is descnbed 
from northern Coahuila, Mexico, where it occurs in shallow soil deposits on 
honzontal limestone slabs. It is outstanding for its unique spine characters. 

KEY WORDS: Cactaceae, ManvnilUiria, Mexico, Coahuila, systematics 



With the following description we put an end to a 44 year old mystery. Originally 
the plant herein descnbed was found in 1952 by Boke as a cultivated specimen of 
unknown ongin. Photographs made by Cutak were published by Backeberg (1961) 
who wrongly identified it as an undescnbed species of Neogomesia. Glass & Foster 
(1978) showed the same plant, identifying it correctly as a species of MammiUaria. 
Bravo & Sanchez-Mejorada (1991, figure 242) published the same photo as 
Normanbokea vatdeziana.

Stems single to branching with up to 7 heads, apex rounded to llatlened, ca. 1.5 
cm in diameter, emerging only slightly above the substrate. Subterranean part of the 
stem naked, carrot-like, corneal with several strongly succulent, tapenng roots, ca. 6 
mm in diameter at base. Tubercles ascending, densely set, very slender, cylindrical, 
up to 5.5 mm long and 1.3 mm in diameter, dark green with a reddish or whitish base, 
becoming dry and deciduous in the subterranean part of the stem. Areoles containing 
some hyaline hairs and up to 80 white spines, densely set in vanous series, porrect to 
radiating, forming a dense flattened cluster 1.3-1.8 mm in diameter, slightly 
rhomboidal in outline, completely covenng the ape.x of the tubercle. Spines 0.4-0.6 
mm long, the uppermost in the areoles slightly longer, whiUsh-translucenl with hyaline 
hairs in the uppermost part, hairs radiating and forming a little umbrella at the spine 
apex. Flowers up to 2 cm long and wide, light magenta. Fruit nearly completely 
sunken in the stem, globular, 4.5 mm in diameter, yellowish green to reddish green 
with up to 15 seeds, drying and leaving a cavity filled with seeds in the stem base. 
Seeds black, globular, ca. 1 mm long and wide, with a basal hilum, slightly separated 
by a faint neck, irregularly oval, 0.8 mm long and 0.4 mm wide. Testa finely pitted. 

The plants grow on honzontal limestone slabs, deeply sunken in a very shallow 
substrate (Figure 1), only 1.5-2.0 cm deep, of sandy clay and fine gravel, growing 
with Selaginella wrighlii, Neolloydia conoidea, Bouleloua gracilis, and lichen. The 
microhabitats are surrounded by typical Chihuahuan Desert vegetation, dominated by 
Agave lechuguilla. Dasylirion sp.. Yucca elaia, Yucca sp., Fouquieria splendens, 
Escobar ia tuberculosa, and Glandulicactus uncinatus. 

Marnmilkuia luethyi is known only from the type locality, which has been 
purposefully withheld to protect the habitat from collecting. The exact locality data are 
deposited with the holotype. 

Mammillaria luethyi belongs to the senes Herrerae, together with M. hu/nboltii, M. 
herrerae, M. albiflora, and M. sanchez-tnejoradae, this last being its closest neighbor, 
growing to the southeast in Nuevo Le6n. The species of senes Herrerae share several 
characters, e.g., fruits sunken in the stem, a high number of white radial spines, lack 
of central spines and the distribution as narrow endemics on limestone rock in eastern 
M6xico from Querdtaro to Coahuila (Liithy 1995). Matmmllaria lueth\i differs from 
M. Sanchez mejoradae in the arrangement and \estiture of the spines (\s. pectinate, 
plumose) and the color of the flower (vs. white). Superficially it resembles M. 
saboae, of senes Longi/lorae, from which it differs in the habitat (vs. \olcanic rock), 
spine insertion, count, length, and vesuture (vs. a single senes, 17-25, ca. 2 mm long, 
glabrous) and flower size (vs. 4 cm long and wide). 

This remarkable Mammillaria is named for Jonas M. Luthy, one of its co- 
discoverers, a Swiss botanist and student of the genus Manvnillaria, w ho alter a Hash 
of intuition pointed to its exact location on his map and spoke, 'This is w here the plant 
grows." And there we found it.

TURBINICARPUS BOOLEANUS (CACTACEAE), A NEW SPECIES FROM 
NUEVO LEON, MEXICO 



George S. Hinton 
Apartado Postal 603, Salullo, Coahuila, MEXICO 25000 

ABSTRACT 

A new species of Turbinicarpus, T. booleanus G.S. Hinlon, is 
descnbed from Nuevo Leon, Mexico, where il occurs on gypsum outcrops. A 
map showing the distribution of the new species and the other tuberous-rooted 
taxa of Turbinicarpus, T. mandragora. and T. subterraneus var. subterraneus, 
IS also provided. 

KEY WORDS: Cactaceae, Turbinicarpus, Mexico, Nuevo Leon, gypsum, 
systematics 



Some species of Turbinicarpus (Backeb.) Buxb. & Backeb. occur consistently 
throughout the gypsum outcrops in Nuevo Le6n, Mexico. The gypsophilic species are 
usually like those that were once included in the genus G\mnocactus Backeb., a 
remarkable exception being the recently descnbed T. hoferii. Liithy & A.B. Lau from 
the gypsum to the north of Arambem, Nuevo Leon. Like other genera with 
gypsophilic members in this area, notably Leucophyllum, Verbesina. Sedum, 
Aztekium, Geohinlonia, Jaimehintonia, and Sophora, Turbinicarpus conlams narrowly 
endemic ta.xa which are often restricted to a single gypsum outcrop. The present 
novelty occurs in the Mumcipio of Galeana, in two localities separated a few 
kilometers from each other.

Stems single, rarely branching, broadly obovate, 2.5-4.5 cm high, 2.5-5.5 cm in 
diameter, basally truncate in older specimens. Roots connected to the stem by a 
narrow, hypogeous neck; neck 1-5 cm long, 3-5 mm in diameter, usually straight but 
occasionally curved or angled. Roots tuberous, pynform to globose, 0.8-2.8 cm m 
diameter, 1.2-5.7 cm long. Stems tuberculate, the axils naked; tubercles rhomboidal 
in cross section, lacking a dorsal sulcus, green, white-dotted, ca. 4 mm high, ca. 5 
mm wide at the base, arranged in 13 and 21 spirals. Areoles elliptical 1.5-2.0 mm 
long. 1 mm wide, villous near apex, later glabrous, ca. 8 mm apart. Central spines 2, 
ca 0.3 mm in diameter at the base, terete, proximally white, turning brown, then black 
above, the apical antrorse, mostly 12-15 mm long, ranging from 10 to 24 mm, the 
basal porrect, mostly 12-18 mm long, ranging from 10 to 21 mm. Radial spines 
mostly 18 to 20, rarely as few as 14 or as many as 28, acicular, white, the extreme 
apex usually brown or reddish; the lowermost (retrorse) radial spines shortest, these 
ca 3-6 mm long and 0. 1 mm in diameter at the base, progressively longer above, the 
uppermost (antrorse) radial spines longest, usually ca. 17 mm, rarely to ca. 29 mm 
long, 0.2 mm in diameter at the base. Flowers ca. 2 cm in diameter, ca. 2.5 cm high. 
Outer penanth segments oblong, entire, mucronulate, the lowermost ca. 8 mm long 
and 3 mm wide, with a white, translucent margin, midvein green, becoming dark 
purple above. Inner perianth segments narrowly oblanceolate, apex emarginate and 
often mucronulate, ca 15 mm long and 4 mm wide, paJe to dark magenta with darker 
midvein. Anthers yellow; Tilaments yellow. Style ca. 1 1 mm long; stigma lobes 7 to 
9, pale yellow, protruding ca. 5 mm above the anthers. Fruit dark green to purple, 
pulverulent, longitudinally dehiscent, ca 6 mm in diameter and 7 mm high, attached at 
the base of an apical areole, with two stramineous scales ca. 1 mm long. 

In the treatments of both Anderson ( 1986) and Bravo et al. (1991), Turbinicarpus 
booieanus will key to T. rrumdragora (A. Berger) A.D. Zimmermann and T. 
subterraneus {Backcb.) A.D. Zimmermann var. subterraneus because of their tuberous 
roots connected to the stem by an elongate neck. These three taxa are widely separated 
geographically (Map 1). Turbinicarpus booieanus is unique among them in having 
only about a third of the main stem body above ground; this correlates with the porrect 
central spines which are directed verucally. In the length of its neck, T. booieanus is 
more similar to T. mandragora, but the latter has a more or less globose, epigeous 
bcxly; brown-tipped (vs. mostly black) central spines that spread perpendicularly away 
from the body; fewer radial spines per areole (8 to 14 vs. 14 to 28); and white (vs. 
magenta) flowers. This species is known only from its type locality, near Parras, in 
southern Coahuila Though closer geographically to T. subterraneus var. 
subterraneus, T. booieanus is easily distinguished from this taxon by its shorter, 
thicker, hypogeous neck with parually hypogeous body; and more and longer radial 
spines that are brown at the apex (vs. glassy-white throughout). Turbinicarpus 
subterraneus var. subterraneus grows about 75 km to the south of T. booieanus on 
low shrubby limestone hills with Agave. Dasylirion, Flourensia. Larrea, Mortonia. 
and Yucca, the plants incredibly suspended on their long necks. Turbinicarpus 
booieanus is found infrequently only on bare, exposed gypsum slopes with Dasylirion 
berlandieri, Muhlenbergia gypsophila, Pinus greggii. SelagineUa gypsophila, and 
Yucca decipiens.

INDEX TO REVIEWERS, VOLUME 79 



The editor expresses his most sincere appreciation to the following individuals. 
These are persons who have reviewed papers that were submitted for publication in 
volume 79 of Phytologia. Without the willingness and diligence of these reviewers, 
the task of the editor would be much more difficult, and the quality of the papers 
published would be lessened. To each of you, I offer my most sincere thanks.
