The Mystery of Malanga: Possible Roles of Xanthosoma Violaceum In THE MYSTERY OF MALANGA: POSSIBLE ROLES OF XANTHOSOMA VIOLACEUM IN ANCIENT MAYA DIET, CULTURE, AND AGRICULTURE by THERESA HEINDEL B.A. University of Wisconsin – Madison, 2010 A thesis submitted to the Faculty of the Graduate School of the University of Colorado – Boulder in partial fulfillment of the requirement for the degree of Master of Arts Department of Anthropology 2012 This thesis entitled: The Mystery of Malanga: Possible Roles of Xanthosoma violaceum in Ancient Maya Diet, Culture, and Agriculture written by Theresa Heindel has been approved for the Department of Anthropology Payson Sheets Gerardo Gutiérrez Date Dec. 7th, 2012 The final copy of this thesis has been examined by the signatories, and we Find that both the content and the form meet acceptable presentation standards Of scholarly work in the above mentioned discipline. iii Heindel, Theresa (M.A., Anthropology) The Mystery of Malanga: Possible Roles of Xanthosoma violaceum in Ancient Maya Diet, Culture, and Agriculture Thesis directed by Professor Payson Sheets ABSTRACT Until the mid-20th century, Ancient Maya agriculture has historically been discussed almost exclusively in terms of maize cultivation and the use of swidden methods. More recent ideas about alternative subsistence strategies and crops that could either supplement swidden or introduce more intensive maize agriculture, however, have led to more questions than answers. While the possibility of root crop utilization by the ancient Maya had been suggested by scholars as early as the 1960s, serious consideration has only occurred since the recent discovery of a Classic period manioc (root crop) field near the ancient village of Cerén in El Salvador by Dr. Payson Sheets. The discovery of such intensive manioc cultivation, along with the sophistication and extent of manioc use, suggests that other root crops may also have been important components of Maya agriculture. The little-known root crop that today is commonly referred to throughout Central America as “malanga” (Xanthosoma violaceum) was uncovered in previous investigations (beginning in the 1970s) at the site of Cerén, which included the excavation of a household garden containing malanga plants. Through the use of ethnography, ethnohistory, iconography, and archaeology, I have compiled a summation of malanga’s possible role(s) in ancient Maya agriculture, as well as how to continue research on the plant. Ethnographic research, for instance, has led to the argument that malanga was most likely processed in a similar way to manioc, which suggests iv that use-wear analyses may provide evidence for malanga use when less durable indicators like starch grains are lacking. Ethnohistoric evidence has been instrumental in providing ideas for how root crops like malanga may have been used, such as for famine food or as a supplementary crop, while iconography has indicated that malanga may have had religious importance as well. Lastly, the use of archaeology, in combination with the above, suggests that malanga would most likely have been grown in swampy, inundated soils in a kitchen garden setting. Through my research on malanga, I believe I have provided new and important information on the ancient Maya diet and on how to continue searching for a previously unknown crop. ACKNOWLEDGEMENTS I would like to thank, first and foremost, my advisor Dr. Payson Sheets. He has been with me every step of the way and, without his thoughtful suggestions and constant help, malanga would still be unknown and this thesis would never have been written. A big thank you should be extended to David Lentz as well, who was kind enough to lend me his botanical expertise. Certainly, without him, I wouldn’t know the difference between taro and malanga. I would also not have been able write a large portion of this thesis without the aid of Gerardo Gutiérrez and his impressive ethnohistoric document collections and Inga Calvin’s iconographic assistance. In addition, I need to give a huge thank you to both Dr. Gutiérrez and Dr. Arthur Joyce for taking the time to read previous drafts of this thesis and providing invaluable advice. The help and companionship during my work in the field of Chris Dixon, Alexandria Halmbacher, and Céline Lamb is also much appreciated. It is important that I thank everyone else who aided me in the majority of my research in El Salvador as well, including the great and hard-working people at the Museo Nacional David J. Guzman – principally Roberto Gallardo, Lily Limas, and Jorge Rubio. In addition, without the help of Elena and Julio Garcia-Muñoz, Jesus Franco, Salvador Quintanilla, Alejandro Quintanilla, Amicar Najarro, and Oswaldo Guardado, I would know nothing about modern-day uses of “malanga.” Finally, I would like to thank everyone in the Department of Anthropology at the University of Colorado – Boulder for supporting me and my research and, in particular, the wonderful Valerie, Lesa, and Karen, who keep the department together. vi CONTENTS CHAPTER 1.

G.: Two new species of Xanthosoma (Araceae) from South America and notes on the tribe Caladieae. – Willdenowia 35: 333-344. – ISSN 0511-9618; © 2005 BGBM Berlin- Dahlem. doi:10.3372/wi.35.35216 (available via http://dx.doi.org/) Two new species of Xanthosoma sect. Acontias, X. mariae and X. latestigmatum, are described and il- lustrated. They have pilose, pedate leaf blades as have in Xanthosoma only X. plowmanii and X. pottii, and their pollen grains are released as monads, unlike in all other Xanthosoma species, which, as far as studied, release the pollen in tetrads. X. mariae is an evergreen plant mainly distinguished by its dark green velvety lustrous leaf blades with numerous leaflets and tuber-like swellings at the junction of petiole and blade; the gynoecium is of the Acontias type and the ovary is pilose in the lower part. X. latestigmatum is seasonally dormant and has medium green leaf blades with numerous leaflets and no tuber-like swellings; the gynoecium is of the Caladium type (with a very broad stigma) and completely glabrous. The relationship of the genera Caladium and Xanthosoma is discussed, C. paradoxum is transferred to Xanthosoma and the new combination X. paradoxum validated, and a key to the genera of the tribe Caladieae given. Introduction Two new species of Xanthosoma Schott cultivated in recent years in the Botanischer Garten München are described here. X. mariae has been collected only once in Peru by Mary Sizemore.

The result showed that the flowers contain saponins (6.61% and 5.50% respectively for the two species). Alkaloids of 6.22 and 9.80% respectively were also obtained from the result. Other Phytoconstituents like flavonoids, glycosides, phenols, steroids, and tannins were also evaluated. The proximate analysis revealed that the flowers contain high protein content (37.87% and 22.56% respectively), high moisture content and crude fat. Colocasia esculenta showed high percentage of total carbohydrate. The flowers of the two species of Cocoyam can therefore serve as spices and source of protein in local meals.

    Elaboration and Evaluation of Typical Puerto Rican Dishes Prepared with Mixtures of Plantain, Cassava and Tanier Flours 1 Isabel B. de Calo ni and Jose R. Cruz-Cay2 ABSTRACT Mixtures of flours from plantain (Musa acuminata x balbisiana AAB), cas­ sava (Manihot escutenta Crantz) and tanier (Xanthosoma spp) were prepared for the elaboration of typical Puerto Rican dishes. The proportion of flours blended were the following- 50:25:25, 60:20:20, 75:15:10 and 75:10:15 of plantain, cassava, and tanier, respectively. Plantain flour was always used as the main flour because of the commercial importance of this crop on the Island. The blends were prepared with 454 g of combined flours mixed with 1250 g boiling water, 11.5 g of salt and 36.0 g of annatto seed in oil (achiote). "Pasteles" and "alcapurrias" (a boiled meat pie and turnovers, respectively), were prepared and found acceptable by a trained taste panel. No significant difference in general acceptability was observed among the samples prepared with the mixtures of flours when fresh and after 3 months frozen storage. INTRODUCT ION Plantain (Musa acuminata X balbisiana AAB), cassava (Manihot es­ culenta Crantz) and tanier (X anthosoma spp) are starchy crops commonly used in tropical countries such as Puerto Rico. Plantain production ranks third in importance among ail food crops (3). Gonzalez Villafane (4) concluded that as a result of the adoption of modern technology recom­ mended by the Agricultural Experiment Station farmers can increase their yields greatly. To deal with problems of overproduction during the summer, it is necessary to process new products from plantains.

AUGUST 2003 Uliga Figure 1. Majuro Atoll THE VASCULAR PLANTS OF MAJURO ATOLL, REPUBLIC OF THE MARSHALL ISLANDS ABSTRACT Majuro Atoll has been a center of activity for the Marshall Islands since 1944 and is now the major population center and port of entry for the country. Previous to the accompanying study, no thorough documentation has been made of the vascular plants of Majuro Atoll. There were only reports that were either part of much larger discussions on the entire Micronesian region or the Marshall Islands as a whole, and were of a very limited scope. Previous reports by Fosberg, Sachet & Oliver (1979, 1982, 1987) presented only 115 vascular plants on Majuro Atoll. In this study, 563 vascular plants have been recorded on Majuro. INTRODUCTION The accompanying report presents a complete flora of Majuro Atoll, which has never been done before. It includes a listing of all species, notation as to origin (i.e. indigenous, aboriginal introduction, recent introduction), as well as the original range of each. The major synonyms are also listed. For almost all, English common names are presented. Marshallese names are given, where these were found, and spelled according to the current spelling system, aside from limitations in diacritic markings. A brief notation of location is given for many of the species. The entire list of 563 plants is provided to give the people a means of gaining a better understanding of the nature of the plants of Majuro Atoll.
