New records for the genera Codonocarpus (n = 14), Gyrostemon (n = 14) and Tersonia (n = 14) are given. The base number for the family Gyrostemonaceae is shown to be x = 14: this is markedly different from that of the Phytolaccaceae sensu stricto (x = 9), in which it was once included.

New records of 5 species of Passiflora subgenus Decaloba (Passiflora amalocarpa, P. auriculata, P. longilobis, P. saxicola, and P. transversalis) from various municipalities, Brazilian states, and Latin American countries are documented. Therefore, this survey contributes to the knowledge and geographical distribution of the family Passifloraceae sensu stricto. Records of P. longilobis and P. transversalis, species previously considered endemic to Brazil, were confirmed from Bolivia and Panama, and from Argentina, Paraguay, and Uruguay, respectively.

Passiflora L. belongs to the family Passifloraceaesensu stricto, and comprises 700–750 species. There are approximately 161 known species of the family in Brazil, of which 153 belong to Passiflora, 89 are endemic, 83 occur in the region of the Atlantic Domain; 40 occur in Rio de Janeiro State (RJ). Using field samplings techniques and scientific collection analyses, we present here new geographic records for Passiflora deidamioides Harms, P. imbeana Sacco, P. junqueirae Imig & Cervi, and P. truncata Regel for RJ, principally in the Serra dos Órgãos National Park (PARNASO). Geographic distribution data was used to calculate the Extension of Occurrence (EOO) and Area of Occupancy (AOO) of the species. Passiflora junqueirae, previously considered endemic to Espírito Santo State, now has new records for RJ. Passiflora imbeana and P. truncata are extended into RJ, being recorded there for the first time in the municipality of Teresópolis. The four species are cited for the first time in PARNASO, occurring between 1,000 and 1,700 m.a.s.l. in Montane and Upper Montane Atlantic Rainforest. We provide taxonomic information, distribution maps, and the conservation status of the species.

Chromosome numbers are given for 69 collections of 24 species of Cruciferae in the genera Alyssum, Arabidopsis, Arabis, Barbarea, Cakile, Eutrema, Hali-molobos, Nasturtium, Rorippa, Thellungiella, and Turritis. The following chromosome numbers are reported for the first time: Alyssum desertorum, n = 16; Arabis canadensis, 2n = 14; A. divaricarpa, 2n = 13 + 2B, 14, 20 + 2B, 21, 28; A. drummondii, 2n = 20; A. holboellii, 2n = 13 + 2B, 20 + 2B; A. lemmonii, 2n = 14; A. lyallii, 2n = 21; A. lyrata, 2n = 32; A. pendulocarpa, 2n = 14; Barbarea orthoceras, 2n = 16; Cakile edentula, 2n = 18; Rorippa curvisiliqua, 2n = 16; Thellungiella salsuginea, 2n = 14. It is concluded that species of Arabis native to North America and western Greenland have the base number x = 7 and many of them are apomictic whereas Eurasiatic species of this genus have an x = 8 base number and are sexual.

Chromosome Level

Chromosome numbers are reported for 22 genera and 116 species of the Epacridaceae.In the tribe Styphelieae, haploid numbers of 4, 6, 7, 8, 9, 10, 11, 12, and 14 occur. This numerical sequence does not represent a continuous siries either of decrease or increase, but is built up from polyploid and aneuploid changes on base numbers of x = 4 and x = 6. Polyploid series on base 4 are found in Cyathodes, Astroloma, and Leucopogon � Pleuranthus, on base 6 in Leucopogon � Perojoa, and on base 7 in Lissanthe. Aneuploidy is also found within genera, but is generally more characteristic of particular genera. In the Epacrideae, the usual haploid numbers are 13 and 12, and only one case of polyploidy is reported. Two species of Sphenotoma possess haploid numbers of n = 6 and n = 7 respectively. The base number for the Epacrideae is probably x = 6, and a relationship between the Epacrideae and the Styphelieae at the 6-chromosome level may be accepted. Any relationship between the Epacrideae and the Ericoideae at an amphidiploid level is denied. With the exception of probable autotriplolds in Lissanthe montana, meiosis is essentially regular throughout the family. Tetrad-type pollen is characteristic of the Epacrideae. In the Styphelieae, the pollen is usually monad (S-type) and never truly single. Three variants in the pattern of pollen development occur in the tribe, modified monad (S-type), full tetrad (T-type), and segregating tetrad (A-type). Variants in pollen development pattern are associated with aneuploidy. The Epacridaceae must have had an ancient origin. Features of species distribution suggest that many may be post-Miocene in origin. Most of the genera must have been established in the early Tertiary, and the differentiation of the two tribes, the origin of the monad pattern of pollen development, and some fundamental changes in chromosome structure in the Styphelieae, permitting a period of chromosomal instab~lity during their evolutionary diversification, must have been still more ancient.

Chromosome numbers and taxonomic discussions are given for North American material of species in the genera Braya and Cardamine. The following chromosome numbers are reported for the first time: Braya humilis s.l., n = 14 and 2n = 28; Cardamine angulata, n = 20, and 2n = 40; C. cordifolia, 2n = 24; C. microphylla, 2n = 32; C. occidentalis, n = 32 and 2n = 64; C. oligosperma, 2n = 16; C. pensylvanica, 2n = 64; C. umbellata, n = 24 and 2n = 48. It is concluded that the base number of Braya is x = 7 not x = 8 and that North American species of Cardamine have the base numbers x = 6, 8, and 10.

Abstract Borrelia burgdorferi, the spirochete that causes Lyme disease, is endemic and widespread in Wisconsin. Research in the northeastern United States has revealed a positive association between Babesia microti, the main pathogen that causes babesiosis in humans, and Bo. burgdorferi in humans and in ticks. This study was conducted to examine associations between the disease agents in the Upper midwestern United States. Ixodes scapularis Say nymphs (N = 2,858) collected between 2015 and 2017 from nine locations in Wisconsin were tested for Babesia spp. and Borrelia spp. using real-time PCR. Two species of Babesia were detected; Ba. microti and Babesia odocoilei (a parasite of members of the family Cervidae). Prevalence of infection at the nine locations ranged from 0 to 13% for Ba. microti, 11 to 31% for Bo. burgdorferi sensu stricto, and 5.7 to 26% for Ba. odocoilei. Coinfection of nymphs with Bo. burgdorferi and Ba. odocoilei was detected in eight of the nine locations and significant positive associations were observed in two of the eight locations. The prevalence of nymphal coinfection with both and Bo. burgdorferi and Ba. microti ranged from 0.81 to 6.5%. These two pathogens were significantly positively associated in one of the five locations where both pathogens were detected. In the other four locations, the observed prevalence of coinfection was higher than expected in all but one site-year. Clinics and healthcare providers should be aware of the association between Ba. microti and Bo. burgdorferi pathogens when treating patients who report tick bites.
