Since the first species description in 1796, there have been numerous changes and additions to this group, including its split into a separate genus, Diplacus Nutt. Recent treatments also have little consistency between them. McMinn 1951 retains this group as a separate genus, Diplacus Nutt., and recognizes fourteen species. Munz (1973) included the group under Mimulus , and recognized six species, four subspecies, and one variety. In The Jepson manual: higher plants of California (Hickman [ed.] 1993), Thompson (1993) places all but one of these into a single species. Due to this inconsistency in treatments, this project attempts to resolve the confusion by addressing the morphological variation within this group to delineate species. Funding received by the Southern California Botanists' 1999 Grant program was essential for travel to a variety of field sites throughout California. The research conducted during the spring 1999 field season focused on three primary goals: (1) to identify named species and subspecies using existing keys and descriptions; (2) to see if the species can be separated by differences in features of the corolla, calyx, pedicel, and leaves, and; (3) to determine if hybridization is contributing to the confusion in the taxonomy of the group. METHODS AND MATERIALS Collections of species were made in California at locations shown in Figure 1 . This group is found in numerous habitat types, and to elevations of 2300 m. Species and subspecies located with uniformity among the populations were: Mimulus longiflorus (Nutt.) A.L. Grant, M. longiflorus ssp. calycinus (Eastw.) Munz, M. bifidus Pennell, M. bifidus ssp. fasciculatus Pennell, M. aurantiacus Curtis, and M. puniceus (Nutt.) Steudel. Populations without constancy in color or morphology may correspond to the named taxa Mimulus longiflorus var. rutilus A.L. Grant, M. aurantiacus ssp. australis (McMinn) Munz, and M. aurantiacus ssp. lompocensis (McMinn) Munz. Again, all of the above named taxa are subsumed under Mimulus aurantiacus in The Jepson Manual: higher plants of California (Thompson 1993). 2 CROSSOSOMA 26(1), Spring-Summer 2000 [issued February, 2001] CROSSOSOMA 26(1), Spring-Summer 2000 [issued February, 2001] 3 Twenty-one measurements were made of corolla, calyx, pedicel and leaf characteristics, as are listed in Table 1 . Ten of these corolla features were chosen to characterize both size and shape of the upper and lower corolla lobes, length of the entire corolla, and the length of the tube inserted in the calyx. Five-hundred and twenty-four plants were sampled, and three flowers per plant were measured. Vouchers for each plant sampled are located at California State Polytechnic University, Pomona (CSPU).1 Table 1. Measurements 1 corolla length 12 length of long filament 2 apex of upper lobe to inner sinus 13 length of short filament 3 apex of upper lobe to outer sinus 14 calyx length to upper lobe 4 distance across lower lobes 15 calyx length to lower sinus 5 height of inflection 16 calyx height 6 width of lower center lobe 17 pedicel length 7 length of lower center lobe 18 pedicel width 8 opening of throat 19 leaf length 9 height of corolla 20 leaf width 10 11 corolla tube length style length 21 stem width below measured flower PRELIMINARY RESULTS Preliminary analysis of these data using Principal Components Analysis displayed in Figure 2 indicates that these measurements are useful in separating the species by differences in morphology. Species high on Factor 1 have large corolla features and large calyx features. Those high on Factor 3 have long style, filament, and pedicel length. This graph represents 68 percent of the total variation among the twenty-one variables. Note that two distinct groups are found: those with large corolla features, namely, Mimulus longiflorus, M. longiflorus ssp. calycinus, and M. bifidus, and; those with small corolla features, namely, M. aurantiacus and M. puniceus. While there is overlap between the species in each of these two groups, other characters, such as flower color or notches in the corolla lobes can also distinguish the species. Numerous other statistical analyses are planned for these data upon collection of the next season of measurements. Hybrids The areas that were most problematic in assigning a species or subspecies name were found in Santa Barbara County, San Diego County, and one area in the northern Sierra Nevada. McMinn (1951) found that fertile hybrids can be made between most of the species. He also mentions numerous instances where he believed that natural hybrids occur with species in central and southern California. Beeks (1962) also noticed that this was a problem in the taxonomy of the group, especially in San Diego County, between Mimulus longiflorus and M. puniceus. Santa Barbara County lies between the distribution of the southern California species, Mimulus longiflorus, and the central coast species, M. aurantiacus. The populations in this area have been named Mimulus aurantiacus ssp. lompocensis. The populations in die area show intermediate floral features between these two probable parental species (Figure 2). However, I do not feel that this named subspecies accurately describes the situation. Moving from the City of Santa Barbara northwest to the town of Lompoc, these populations are not uniform in morphology, and vary greatly in trichome features. ' Editor's note: The majority of the collections at CSPU have been transferred to Rancho Santa Ana Botanic Garden (RSA). 4 CROSSOSOMA 26(1), Spnng-Summer 2000 [issued February, 2001] Factor 1 A M. punioeus M. longiflorus x M. aurantiacus M. brfidus - Santa Bartiara M. longiflorus calyoinus - San Qego Red San Qego Orange M. bifidus fasdculatus Figure 2 Principal Components Analysis with data points on Factor 1 (horizontal) and Factor 3 (vertical) for each plant sampled. Triangles represent the species with smaller corolla features, circles represent those with larger features, and the pluses are possible hybrid populations with intermediate features. San Diego County is a more complex area composed of four named species, two subspecies, and one variety. While most of the the problem populations lie within San Diego county, this problem can also be noticed in parts of Los Angeles, Riverside, and Orange counties. These problematic areas show intermediate floral features between the putative parents; Mimulus longiflorus and M. puniceus. CROSSOSOMA 26(1), Spring-Summer 2000 [issued February, 2001] 5 The northern Sierra Nevada is the only area where Mimulus bifidus is found. The populations sampled show obvious differences from the other species, with large morphological features and distinct notching in the upper corolla lobes. The distribution of Mimulus aurantiacus is said to reach into the foothills of this region, although, I have not yet located populations that resemble what 1 feel to the true M. aurantiacus that occurs throughout the centra] coast of California. However, the other population that I did sample, obviously not belonging to Mimulus bifidus or M. aurantiacus clusters in the intermediate floral morphology region shown in the previous Figure 2. It is very possible that this is an additional region that has a hybridization problem. Due to the poor sample size that I obtained from this region, more collections have to be made in order to accurately assess this problem. Trichomes Calyx and pedicel trichomes are features that vary between species, and have been used in classification of this group. One flower from each plant sampled in this study has been preserved in formaldehyde, and research is currently being done with light and scanning electron microscopy to identify the trichome types of these samples. Preliminary research shows that there are many different types of trichomes found in this group. There are straight and branched hairs of various lengths, as well as straight and branched glandular hairs, as shown in Figure 3. This may be a feature that will not only help to characterize species, but may also help to identify relationships among the hybrid areas in Santa Barbara and San Diego counties. DISCUSSION In most of the populations sampled, I felt that there was much uniformity in corolla color and size components. The species in these areas are distinct, and can readily be identified using existing keys. This aspect of the group leads me to believe that the treatment in The Jepson manual: higher plants of California, with all but one species lumped into Mimulus aurantiacus, does not reflect this distinctness. It is the areas in which overlap occurs between species distributions that may have given rise to the problems with the taxonomy of this group. The Santa Barbara area seems to be a clear case of overlap and hybridization between Mimulus aurantiacus and M. longiflorus. However, the San Diego region is a much more complex area that contains four distinct species, and two less distinct subspecies. Less clear is the extent of the hybridization that has occurred in this complex, and more sampling needs to be done throughout this region. The northern Sierra Nevada is another area that will need much more sampling; I have found only three distinct populations of Mimulus bifidus, as expected, and one possible hybrid population. This project is proceeding in collaboration with Paul Beardsley, a graduate student at the University of Washington, who is focusing on the molecular genetics of the entire genus Mimulus. His preliminary research indicates that section Diplacus is a monophyletic group. With his future analyses of this section and the morphological data from this project, it is our goal to ascertain a clearer picture of the species boundaries in this group. 6 CROSSOSOMA 26(1), Spring-Summer 2000 [issued February, 2001] I ; — — Figure 3 Pedicel and calyx trichomes of Mimulus section Diplacus.

CROSSOSOMA 26(1), Spring-Summer 2000 [issued February, 2001] 7 Common Garden Study of morphological variation in Kusche’s Sandwort (arenaria macradenia var. kuschei) (Caryophyllaceae), a Rare Plant of Southern California Valerie Soza Rancho Santa Ana Botanic Garden 1500 N. College Avenue Claremont, CA 91711 INTRODUCTION Kusche’s Sandwort, previously referred to as Forest Camp Sandwort, Arenaria macradenia S. Watson var. kuschei (Eastw.) Maguire is a perennial member of the Pink Family, Caryophyllaceae, that was recently rediscovered on Liebre Mountain of the Western Transverse Ranges, Los Angeles County, California. The last known occurrence of this taxon was from its original collection in 1929 by J. August Kusche from “Forest Camp, Mojave Desert.” Floristic surveys performed by Rancho Santa Ana Botanic Garden (RSABG) for the Angeles National Forest, USDA Forest Service beginning in 1994 revealed several populations of this taxon along the summit of Liebre Mountain (Ross and Boyd 1996). To date, seven populations of A. macradenia var. kuschei have been located on Liebre Mountain. The majority of these populations are located in the vicinity of recreational or traffic areas, as in roads or campsites (Boyd 1997). As a result of these surveys, this taxon has been placed on the Angeles National Forest sensitive species list. However, with the recent rediscovery of this taxon, questions regarding its taxonomic merit have arisen. Arenaria macradenia is a morphologically variable species. What distinguishes var. kuschei from the other varieties is its relatively compact and densely glandular-hairy inflorescence. Arenaria macradenia var. arcuifolia Maguire is also known from this region of the Western Transverse Ranges, particularly from the San Gabriel Mountains, just east of the Liebre Mountains. It is very similar vegetatively to A. macradenia var. kuschei, but displays a nonglandular inflorescence. A curious trend was noted among the seven populations of var. kuschei on Liebre Mountain with regards to number of glandular individuals present in the populations. The populations furthest west appear to be comprised of glandular individuals of the kuschei- type. However, as one moves east, the populations begin to become increasingly mixed with nonglandular individuals of the arcuifolia-type. No apparent intergradation between the two varieties has been noted within these populations (Boyd 1997). METHODS AND MATERIALS Seeds of Arenaria macradenia were collected from both varieties from six of the seven populations on Liebre Mountain, cleaned and processed, and stored at RSABG. Two of the populations collected from were pure var. kuschei and four were mixed var. kuschei and var. arcuifolia , as shown on Figure 1. Seeds from each population were kept separate by variety, but individuals were pooled (Boyd 1997). Initial seed germinauor trials by Michael Wall, Seed Curator at RSABG, revealed that both morphologies, glandular and nonglandular inflorescence types, were present in the offspring from a single parental type (Wall pers. comm. 1998). In the majority of cases, progeny from the var. kuschei seed pool included both var. kuschei and var. arcuifolia morphology, and vice versa. 8 CROSSOSOMA 26(1), Spring-Summer 2000 [issued February, 2001] CROSSOSOMA 26(1), Spring-Summer 2000 [issued February, 2001] 9 PRELIMINARY RESULTS AND DISCUSSION Our goal in this project is to determine whether or not Arenaria macradenia var. kuschei is a distinct variety or perhaps just an extreme local form of A. macradenia var. arcuifolia. This determination is necessary before addressing conservation concerns about this taxon. Our initial goal was to propagate fifty individuals from seed from each variety from each population sampled on Liebre Mountain under common garden conditions in order to observe inflorescence types and morphological variation among the progeny. Fifty individuals from each of the two pure var. kuschei populations and fifty individuals from both varieties from the four mixed populations would be propagated for a total of five hundred individuals from ten seed accessions. In addition, seeds would be collected from a pure var. arcuifolia population within the vicinity of the Liebre Mountain area for propagation for comparison. Seeds from each variety from each population were originally sown in soil consisting of six parts peat moss, four parts sand, and three parts perlite. Germination results in soil were not very good; the percentage of seeds that germinated ranged from 8% to 49%. Therefore, a second trial was performed on agar plates which were placed in growth chambers at eleven hours light at 20°C and thirteen hours dark at 12°C. Germination results were much better on agar plates with percentages of germination ranging from 76% to 100%. Seedlings were transplanted individually into 2” pots in soil comprised of six parts peat moss, four parts sand, three parts perlite, four tablespoons Osmocote, and one tablespoon Micromax. After approximately three months, seedlings were ready to be transplanted into one-gallon pots. Currently, progeny from both varieties from six of the populations on Liebre Mountain have been propagated and transplanted into one-gallon pots for observation. Our original goal of fifty individuals per seed accession has not been fully attained for several accessions, thus we may need to propagate additional individuals. The total of Arenaria macradenia individuals in one-gallon pots at RSABG is approximately 480, to date. The majority of individuals have not yet flowered. Flowering time for A. macradenia is generally May-June (Munz 1974); however, individuals at RSABG have begun flowering as early as March, with a peak in July and August. Data will be gathered this year, during blooming time, on the presence or absence of glandularity in the inflorescence for each individual to determine the ratios of glandular to nonglandular offspring from each variety from each population. Another component of our project was to collect seeds from a pure Arenaria macradenia var. arcuifolia population on Sawmill Mountain, east of the Liebre Mountain var. kuschei populations; and propagate fifty individuals from this population for comparison of progeny with those from the pure var. kuschei and mixed populations of A. macradenia. On September 21, 1999, seeds were collected from a pure var. arcuifolia population from the northern side of Sawmill Mountain, west of Bushnell Summit, along the Sawmill Mountain Truck Trail, as shown on Figure 2. Seeds were sown in agar plates and grown in growth chambers under conditions described above. Seeds began to germinate after several days, and the majority of seeds had germinated by the seventh day. Seedlings have been transplanted into 2” pots and will be transplanted this year into one-gallon pots when seedlings have matured. In addition, an open-pollinated experimental garden with Arenaria macradenia offspring from the Liebre Mountain populations has been established at RSABG. Offspring from each variety from each population sampled are represented, from two pure var. kuschei and four mixed populations. Five offspring from each variety from each population propagated from seed during initial seed germination trials by Michael Wall have been outplanted from one-gallon pots into the ground. A total of fifty individuals have been outplanted and seed was collected in i999 from each individual in the experimental garden for future studies. The next step in the experimental garden is the addition of five offspring originating from the pure var. arcuifolia population from Sawmill Mountain. Individuals will be outplanted from one-gallon pots into the ground and exposed to an open-pollinated environment and seed will be collected again from all individuals. Seed collected will be used in future propagation studies to observe the morphological variation in the F2 generation of selected individuals of A. macradenia. 10 CROSSOSOMA 26(1), Spring-Summer 2000 [issued February, 2001] not Ihree Points Canyon in^pQfOunc tCa: 44— I - : A - , JS ‘z^Z^z. . <5 - il, X )a O • . gj* 1 V^N Ca£2P^^a_* xr7 JiS JaC-^ "-v. ,r^C a4^&~ r"-- CaWcn-oiina^51 Mounts, J-\ Ljz L — T- tjmore Meadows*, P4 ■+■ .

Muller, in his revision of the genus ( Amer . Midi. Nat. 24:729-742, 1940) recognizes 7 species, two of which were described as new. In 1942, Benson (Amer. J. Bot. 30:239, 630) reduced two species (■ Choisya arizonica Standi, and C. mollis Standi.) to varieties under C. dumosa (Torr.) A. Gray. It is not within the scope of this note to discuss the status of these taxa, but rather to report chromosome information. For the purpose of this note, the three taxa concerned will be referred to as species. To my knowledge, there are no published chromosome counts for any member of the genus. With the object of determining whether cytological information would be helpful in the taxonomy of this group, we collected bud material of the three taxa mentioned above in the standard 3-1 absolute alcohol-acetic acid mixture. Anthers were later squashed in aceto-carmine. While attempting the cytological investigation, we came to understand the reason for no previous counts. The material proved to be very recalcitrant. The chief problem was to collect buds sufficiently immature to be undergoing meiosis.- We eventually found that only buds of "pin head" size were satisfactory. After we became aware of this, we were able to obtain counts for the three taxa concerned. The result offered no help with the taxonomy, however; the number 2 n = 56 was the same for all species. From these data, one might conclude that the basic number is 7, and the plants are all octoploids. Alternatively, they may be tetraploids, with a basic number of 14. Voucher specimens are listed below. The collection numbers are those of J.R. and C.G. Reeder.

This study was conducted several years ago. The reason for delaying the report is that I had hoped to get cytological material of Choisya temata HBK; the type species of the genus. However, in this I was unsuccessful. Clearly, these chromosome numbers should be exhumed from my files and made available to those with an interest in the genus Choisya. John R. Reeder.

(Euphorbiaceae), or leafy spurge to the flora of these mountains, based on a report of its occurrence in "scrub near Malibu Creek, 1 km north of Pacific Coast Highway” (See Sanders Madrono 44(2):205, April-June 1997). According to Mr. Andrew Sanders (personal communication 1 1 December 2000) at the University of California Riverside herbarium (UCR), the specimen upon which the report was based was subsequently re-examined and determined to be Euphorbia terracina L., a species that is becoming widespread in the Malibu area (Wishner, personal observation). This reduces the count of species in the flora by one; now estimated at 876 using The Jepson manual: higher plants of California (Hickman [ed.] 1993) treatment (two or more subspecies or varieties are counted only as one species). This does not include approximately forty additional species known to occur by the author, which are the subject of another manuscript in preparation.

(CDFG 2000), a site threatened by an even more massive Newhall Ranch development. In view of the imminent threat to both extant locations, this species is currently a candidate for listing as California Endangered. These discoveries add one new species to the flora of the Santa Monica Mountains (including the Simi Hills), for an estimate of 877. The disposition of voucher specimens (if any) from these two locations is not indicated in the database report. reference pages -;j859;m673 Literature Cited Baldwin, B.G. 1999.

Riefner, Jr. 17554 Vandenberg-14, Tustin, CA 92780 Xanthoparmelia angustiphylla (Gyelnik) Hale (Ascomytina, Parmellaceae) - Orange Co , Santa Ana Mountains, Cleveland National Forest, upper Fremont Canyon, growing on soil and cobbles in clearings in old growth chaparral, USGS 7.5' Black Star Canyon quadrangle, UTM Zone 11, N3742626, E437789, 7 June 2000, elevation ca. 2,200 ft, Riefner 20-448 (WIS); collection annotated by Dr. John W. Thomson. Previous Knowledge. In North America, Xanthoparmelia angustiphylla is most common in the eastern United States and Canada (Hale 1990, A synopsis of the lichen genus Xanthoparmelia (Vainio) Hale, Smithsonian Contributions to Botany, Number 74, Smithsonian Institution Press, Washington, D.C.). Previously, it was incorrectly named Xanthoparmelia hypopsila (Mull. Arg.), which is now considered to be a South American-South African species (Hale 1988, Mycotaxon 33: 401-406). Xanthoparmelia angustiphylla is rare in California, and was reported only from Siskiyou County (Hale and Cole 1988, Lichens of California. University of California Press, Berkeley). Recently, its range has been extended to include Ventura, San Diego, and San Luis Obispo counties (Riefner et al., 1995, Bulletin of the California Lichen Society 2: 1-11; Magney, 1999, Bulletin of the California Lichen Society 6: 22-27). Xanthoparmelia angustiphylla is a yellowish-green, foliose (leaf-like) lichen, 4- to 10-cm broad that lacks isidia (finger-like outgrowths of the lichen surface) and soredia (vegetative powdery clumps of algal cells surrounded by hyphae); apothecia (cup or disk-like reproductive structures) are common and its spores measure 5-6 x 9- 10|im. It is easily separated from most other species of Xanthoparmelia found in southwestern California owing to its plane black lower surface and the content of stictic acid, which is its principle metabolite (Thomson, 1993, The Bryologist 96: 342- 344). Xanthoparmelia angustiphylla is a close relative of X. conspersa (Ach.) Hale, which has isidia and also has a black lower surface (Hale 1979, How to know the lichens. Wm.C. Brown Company). Xanthoparmelia angustiphylla is found on rock outcrops, pebbles, iron-stone concretions (Carlsbad loams in San Diego Co.), and soil in a number of vascular plant communities including chaparral, maritime scrub, and conifer forests. Significance. This Santa Ana Mountains collection from upper Fremont Canyon represents the first record for that range, and the first record for Orange County. Undisturbed clearings in chaparral and open-soil terraces free of exotic grasses are common in this region, which is characterized by rugged cliffs, deep stream-cut canyons, and cobble-strewn ridge-tops frequently dominated by Adenostoma fasciculatum Hook. & Am. and Ceanothus crassifolius Torrey. Xanthoparmelia angustiphylla is restricted to open-soils in these clearings and terraces, which are sparsely vegetated with native annuals such as Filago califomica Nutt., Stebbinsoseris heterocarpa (Nutt.) Chamb., Plantago erecta Morris, and Stylocline gnaphaloides Nutt., and occasionally rare geophytes such as Dudleya multicaulis (Rose) Moran and Calochortus plummerae E. Greene. These open habitats are mostly underlain by clay-loam soils, and are frequently covered with a conspicuous biological crust comprised of lichens, including Acarospora cf. particularis Magn., Candelariella vitellina (Hoffm.) Mull. Arg., Catapyrenium squamulosum (Ach.) Breuss, Collema tenax (Sw.) Ach., Diploschistes scruposus (Schreber) Norman, and Peltula patellata (Bagl.) Swinscow, and mosses such as Didymodon (Barbula) vinealis (Brid.) Zander, Bryum argenteum Hedw., B. capillare Hedw., Timmiella crassinervis (Hampe) L. Koch, and Tortula brevipes (Lesq.) Broth, in Engl. & Prantl. 16 CROSSOSOMA 26(1), Spring-Summer 2000 [issued February, 2001] This new record is also important because the California Lichen Society has proposed Xanthoparmelia angustiphylla as rare: CNPS List IB - 3-2-2 RED Code (Magney 1999, loc. cit.)- Xanthoparmelia angustiphylla is one of an ever-growing list of organisms that is inexorably tied to undisturbed open-soil habitats encrusted with lichens, bryophytes, and cyanobacteria (blue-green algae). The most notable feature of these crusted micro-sites is the exclusion or near-exclusion of exotic weeds, regardless of the soil type or the vascular plant community. Numerous other rare and/or endangered or unusual species of annual vascular plants, invertebrates, and soil-loving lichens utilize these sunny, open micro-sites (Riefner et al. 1999, Crossosoma 25(2):83-84). Often overlooked, these habitats are rapidly disappearing and provide functions that are important to the conservation of many of these rare and endangered species in southern California (Riefner and St. John, 2000, poster presented at the CalEPPC Conference 2000, Exotic Plants in the Landscape: Processes and Patterns, October 6-8, 2000, Concord, California). Unlike the rare vascular flora of the state, expanding urban development, agriculture, and habitat degradation by exotic plants have caused the loss of unique cryptogamic associations in southern California that has gone relatively unnoticed by resource managers and land-use agencies. CROSSOSOMA 26(1), Spring-Summer 2000 [issued February, 2001] 17 INTERMOUNTAIN FLORA (CRONQUIST ET AL. 1972-1997) TABLE OF CONTENTS AND INDEX TO FAMILIES compiled by Carl Wishner, Editor of Crossosoma I have often thought that an index to the families treated in the Intermountain flora, vascular plants of the intermountain west U.S.A. (Cronquist et al. 1972, 1977, 1984, 1989, 1994, 1997) would be useful, despite the fact that this beautifully illustrated work is presently incomplete. According to the authors, "[a] key to the families of dicotyledons and a comprehensive index for the six volumes will be presented in volume 2, now scheduled to be the last volume to appear." To date, volume 2 has not been published, and not wishing to wait any longer, I have compiled the present table of contents and index at the family level for the existing volumes. The authors of Intermountain flora also indicate that "[t]he organization and linear sequence among the angiosperms are planned to be in general accord with the recent system of Cronquist (1968)" (see volume 1, p. 5). In this regard, one of the authors, Dr. James Reveal (personal communication 27 Jan 2001) makes the following comments: "A great deal of research has been done over the last two decades since Arthur published his 1981 system of classification for the angiosperms. While he made minor corrections in 1988, they obviously could not represent the tremendous growth in the information base that one now uses to ascertain the taxonomic and nomenclatural disposition of several of the taxa that Cronquist accepted. I mention this because it is important to recognize that the linear arrangement given in the Intermountain flora is now dubious, and should not be used for anything other than the stated purpose, an index to the volumes. One needs to be aware of the new literature, and not take at face value what is in the flora." "In Cronquist’ s system, the Ephedraceae belongs to the Ephedrales. While most authors would place the family in the Ephedropsida, this was not what Arthur did, and thus, I suggest that you maintain the Gnetopsida. Also recognize that the "dicots" is a non-existing group. Today, the angiosperms are generally divided into four or five classes; not just the two (Magnoliopsida and Liliopsida) that Cronquist and others maintained until the mid 1990s. Today, there is general agreement that the angiosperms should be subdivided into the Magnoliopsida, Piperopsida, Liliopsida, Ranunculopsida, and the Rosopsida. Some taxonomists prefer to reverse the linear arrangement of the Piperopsida and Liliopsida, while others would prefer to reduce the Piperopsida to synonymy under Magnoliopsida. A newly-published series of papers that appeared late last year suggests that the Nymphaeopsida should to be recognized at the level of class, and positioned prior to Magnoliopsida. I have some difficulty with this, preferring either to position Nymphaeopsida within Piperopsida (as a synonym), or as a separate class just before the Piperopsida. Pending additional information that is anticipated to be published in 2001, a more objective conclusion may logically follow." Before presenting the table of contents and index, I would like to point out those taxonomic groups which have yet to be presented in the missing volume 2, as best I can ascertain with the help of volume 3 of Flora of North America (FNA Ed. Comm. 1997). These include the orders and families of the subclasses Magnoliidae, Hamamelidae, Caryophyllidae, and Dilleniidae, as follows: Subclass Magnoliidae Piperales - Saururaceae Nymphaeales - Nymphaeaceae, Cabombaceae, Ceratophyllaceae Ranunculales - Ranunculaceae, Berberidaceae Papaverales - Papaveraceae, Fumariaceae 18 CROSSOSOMA 26(1), Spring-Summer 2000 [issued February, 2001] Subclass Hamamelidae Urticales - Ulmaceae, Cannabaceae, Moraceae, Urticaceae, Fagales - Fagaceae, Betulaceae Subclass Carvophvllidae Caryophyllales - Molluginaceae, Caryophyllaceae Polygonales - Polygonaceae Subclass Dilleniidae Dillemales - Paeoniaceae Theales - Elatinaceae, Hypericaceae Malvales - Malvaceae Nepenthales - Droseraceae Violales - Violaceae, Tamaricaceae, Frankeniaceae, Cucurbitaceae, Datiscaceae, Loasaceae Salicales - Salicaceae Capparales - Capparaceae, Brassicaceae, Resedaceae Ericales - Ericaceae Primulales - Primulaceae Literature Cited CronquistA. 1968.

Actually, the second issue of Volume 2 in April-May 1976 was the first to bear the name Crossosoma. Over the next 16 years, the publication schedule was somewhat variable, typically comprising 4 to 6 issues per volume, but only one in 1978 (volume 4), and seven in both 1983 and 1984 (volumes 9 and 10). Starting in 1992 (volume 18), the present format was adopted, and each volume was limited to two issues. Now in the 26th year of the journal, no comprehensive index or bibliography has heretofore been undertaken to be compiled, although, Mr. Steve Hartman is credited with having prepared a preliminary spreadsheet of articles to volume 22(1), which he kindly made available to me. Expanding upon Mr. Hartman's effort, and having been provided by Mr. Alan Romspert, our secretary-treasurer with volumes before 1985 that I was lacking, I undertook the task with the present result. The following index contains at least two entries, and frequently several more than that, for each substantial article that has appeared in all volumes of the journal since its inception as SCB News. At the minimum, authors and co-authors are indexed, and at least one key word from the title. Articles dealing with various aspects of a particular species' biology are indexed both by species name and family, and occasionally by common name, and also by recent nomenclature changes (i.e. Stipa changed to Nassella and Achnatherum) reflected in The Jepson Manual. Species names that are indexed are also given a brief descriptive phrase to indicate the nature of the subject, for example: "Lesquerella kingii bemardina, genetic variation in." Where articles pertain to specific locations, these locations are indexed, along with a descriptive phrase. Where such locations are in California, the county or counties are also indexed. A few other recurring items were indexed, such as editorials, book reports, and annual symposium programs (the later through 1991). Items such as field trip announcements, minor editorials, and other matter that was considered to have limited time value are not included in the index. In general, the subject matter that has appeared in the first 26 years of Crossosoma ranges from "aboriginal uses of southern California plants" to "zonation patterns of salt marsh plants." Between those index entries, one might notice the rather diverse array of subjects that have been discussed in the pages of Crossosoma. Noteworthy are the extensive contributions to knowledge of the flora of Baja California by our own Emeritus Professor, Dr. Robert Thome of Rancho Santa Ana Botanic Garden. Over the years, Earl Lathrop, Curtis Clark, and recently, Peter Bowler, have also been major contributors to the journal. In all, approximately 127 articles have appeared in Crossosoma, dealing with diverse aspects of botany in southern California, and Baja California. A bibliography of articles that have appeared in the first 26 years of Crossosoma follows the index. I sincerely hope that the present index and bibliography will be of value to the readers of Crossosoma. I apologize for any errors, omissions of authors, or inadequate indexing of any article. Please bring any omissions or errors to my attention. — Carl Wishner, Editor, Compiler 30 CROSSOSOMA 26(2), Fall-Winter 2000 [issued February, 2001].
