This Bulletin attempts to present an account of that flora in California which is visited by the honey bee for the purpose of gathering nectar, other sweetish material, pollen and propolis. There has been no work of this kind heretofore published; and what literature we possess is but fragmentary, being confined to a few short accounts and notes in the various apicultural and agricultural journals on some honey plants. Owing to a demand among the beekeepers for a work of this kind, and as six other states — Texas, Nebraska, Massachusetts, Arizona, Oklahoma, and North Carolina— already possess lists (Experiment Station Bulle- tins1) of their honey-producing floras, this station has seen fit to prepare this publication. It is the result not only of a compilation of all litera- ture obtainable upon the subject, but also of field work in different parts of the State during the past four years. Many beekeepers have been consulted on the university demonstration train, at various farmers' institutes and beekeepers' conventions. The nomenclature that has been followed is that of the Index Kewen- sis, Plantarum Phanerogamarum. Local common names have been noted whenever known. If more than one name is given, the first mentioned should be preferred to all others, either because most frequently used, or for other reasons. The statements of the geographical distribution of many of the differ- ent species are taken from botanical works of California. When this is so, the quotation is followed by the name of the author alone. The publications referred to are the following : W. L. Jepson, "Flora of Western Middle California." LeRoy Abrams, "Flora of Los Angeles and Vicinity." H. M. Hall, "Composite of Southern California." For descriptions of most of the native species, the reader is referred to the above publications. The account of each plant gives, in as condensed a form as seemed advisable, all information that will tend to help the beekeeper in ascer- taining its value as a honey plant. This knowledge, if gleaned from literature, receives the author's name and reference is made to the citation. All other accounts are the result of personal observations by the writer, except in those cases where "reported to" or similar state- ments are made, in such cases they are the result of either conversation or correspondence with beekeepers. A star prefixed to the name of a JThe North Carolina List is published by the North Carolina Department of Agri- culture. 974 UNIVERSITY OF CALIFORNIA EXPERIMENT STATION. plant indicates that a specimen of that plant is to be found in the herbarium (54 species) of "The Honey Producing Flora of Calif ornia," of the University of California, which is open to the inspection of the beekeepers of the State. It must be noted that atmospheric conditions play an exceedingly important part in the quantity of nectar secreted by the different plants. A good honey plant in one locality may prove actually worthless as such ML Relief Map ^SK^ of f » CALIFORNIA " '^^k. showing the '< m^ HONEY REGIONS V- ' ■ "^ J| ' ~':'^k K-KIamath region. & N-Northern fifc, valley. ^F- Foothills of ^L the Sierras. v$SjH\ ^L B- Bay region ^f.v;. t^r fr^k^B'* ' .. : ^k C- Central ^S^Sl^S'"- Wk valley.

A difference of only a few miles may show a marked change in the nectar-secreting powers of some plants; a fact which has given rise to the so-called "alfalfa honey belt" and "lima bean honey belt." The color, aroma, body and granulating propensity of honeys are like- wise influenced by climatic conditions as well as by altitude, the char- acter of the soil and its moisture content. The color of honey, but only to a very slight degree, is affected also by the character of comb (brood) in which it is stored. A difference of opinion among beekeepers, as to BULLETIN 217] HONEY PLANTS OF CALIFORNIA. 975 the source of some honeys, is often due to a failure to recall that an exceedingly small amount of aromatic honey may impart a characteristic flavor to a large bulk of mild honey. These basic factors in determining the nectar-secreting values of plants have been mentioned in order to point out : first, how necessary it is to make close and careful observations in determining the real worth of a plant throughout its entire distribution as a yielder of nectar, and, secondly, that the beekeeper in making a selection of honey plants in a given vicinity, should do so very cautiously, ever bearing in mind that an excellent honey plant in one locality may not live up to its reputation in another. The present bulletin is by no means complete, and must be considered merely as a preliminary account of our melliferous flora. The writer's intention is to continue this work, and any additional data and informa- tion pertaining to bee botany, as well as the correction of whatever errors that may be found, will be appreciated. He wishes to thank Dr. H. M. Hall for the assistance which he has given in the identification of some of the flora and in the arrangement of the botanical sequence herein followed, and in reading the proof. To Professor W. L. Jepson, who has rendered valuable help, and to Pro- fessor C. W. Woodworth, under whose supervision this Bulletin has been written, he wishes also to extend his thanks. THE DISTRIBUTION OF THE HONEY PLANTS. California possesses an unusual number of different forms of plant life. This is, to a great extent, due to a diversified topography and to the resulting influence this bears upon climate. If the State be con- sidered geographically, it may, from the standpoint of the distribution of its melliferous flora, be divided into eleven districts. These districts, although they contain many honey plants in common, yet possess enough different forms to materially change the methods of beekeeping in each of the several districts. The different honey flora of the various sections is, to a certain extent, responsible for this. Not only has each such division many different honey-producing plants, but in some cases where a plant is a good producer in a number of regions, it may, in one particular region, be so influenced by either climate, altitude, soil, etc., that it will yield little, if any, nectar. The boundaries between these divisions are by no means distinct, for that boundary line which would satisfy one plant would not necessarily include the zone of another. The relative importance of the honey plants of each district is given in brief survey in the following para- graphs : 976 UNIVERSITY OF CALIFORNIA — EXPERIMENT STATION. SOUTHERN COAST RANGE. (S) Those eucalypti grown very near the coast where they are favored by warm winter weather often furnish the bees with a twenty to a fifty pound surplus during the winter months. Along river bottoms the willow and Cottonwood provide the first bloom to stimulate bees to breeding, and, on the higher foothill sagebrush ("old man") and manzanita are the first to start activity among the bees. The acacia, wherever grown, also furnishes some of the first pollen. Following these there is an abundance of minor bloom, such as wild cherry, ceano- thus, buckthorn, wild currant, wild blackberry, oak, poison oak, and figwort. Those spring plants known to yield surplus crops are : filaree, burr clover, mustard (Lompoc Valley), caterpillar phacelia (Ventura County), orange, and black sage, the latter, as is well known, is the principal honey plant of southern California. The summer bee forage consists of the black, purple, and white sages (blooming in the order named), wild alfalfa, horehound, barberry, pepper tree, and sunflower. On the sand dunes in San Diego County ice plant yields a white honey which candies very readily. In the vicinity of Ventura and Oxnard the lima bean yields an excellent honey during parts of July and August. Late summer and fall plants are : white sweet clover, Christmas berry, tarweed (a dark and bitter honey), sumac, wild buckwheat, turkey mullein and blue curl. The leading honey-producing counties are, in the order named, Ventura, Los Angeles, San Diego, Orange, and Santa Barbara. IMPERIAL VALLEY. (I) This is the only section in California where a scarcity of pollen may exist. The bloom of the wild hollyhock is the first for the bees to visit, and when this ceases they go to work upon the cantaloupes which come into bloom soon after, and which* furnish an abundance of pollen, as well as yielding some honey. During the latter part of May arrow weed, growing along irrigation ditches and canals, secretes a great deal of nectar, but alfalfa coming into bloom at about the same time, is the main source of honey in the valley. There is a constant flow from this source, but occasionally the first crop does not yield as much as the others, while the last crop is a little dark in color. Mesquite is the last to yield honey, but it is not at all constant in its secretion ; one year the bloom lasting three weeks and another year only one week. It has, however, two blooming periods, both of which vary to a considerable extent. Cot- ton is now being planted in the valley to a considerable extent, and it may prove valuable for the beekeeper. Eucalyptus rostrata, which does well here, and the date palm, which also will, no doubt, be under extensive cultivation before long, are plants which bee men are looking BULLETIN 217] HONEY PLANTS OF CALIFORNIA. 977 upon with much favor. Much of the information regarding the honey plants of this valley has been secured from Mr. George of this section. PLATEAU REGION. (P) The willow and cottonwood along river beds and the manzanita (2,000 to 9,000 feet, November to February)1 are again the two chief plants that are responsible for the earliest breeding among the bees. Eucalypti, however, whenever planted, aid materially. Wild lilac (pollen), buck- thorn, filaree (300 feet, January to May), and Phacelia tenasitifolia are the very early spring plants. The orange is a splendid yielder in the vicinity of Kiverside, Redlands, and San Bernardino. Next comes the black sage (1,700 to 5,000 feet, April to June), wild alfalfa (1,200 to 2,500 feet, June to July), wild buckwheat (1,200 to 5,000 feet, July to December), and sumac; all of which are excellent producers. What is known as "Straight Up Cactus" by some of the beekeepers of these mountains is reported to yield considerable honey. The Yucca and prickly pear are also good yielders. During the fall a good deal of blue curl honey is stored, and late fall showers do not greatly alter the con- stancy of nectar secretion of this plant at a 2,300-foot altitude, on the plains of the Sacramento and San Joaquin valleys, however, an unusual nectar secretion of blue curls follows a light, soft rainfall. The counties of this district that figure in honey shipments are San Bernardino, Riverside, San Diego, Inyo, and Kern. SANTA CATALINA ISLAND. (X) Much of the honey-producing flora of this island is greatly reduced by some twenty-five thousand head of sheep. Even a large percentage of the bloom of the black and white sage is yearly eaten by sheep. Yet eucalypts, Christmas berry, and a great abundance of sumac will always afford a quantity of nectar. In March and April, when there is but little wind, the bee forage consists of the caterpillar phacelia, phacelia ramosissima and sow-thistle, followed by oak, tocalote, and an abundance of turkey mullein. OWENS VALLEY. (O) Mr. William Muth-Rasmussen of Independence has kindly furnished the following information. He states that with three or four feet of snow on the ground in January a good crop of honey is usually assured. Willow is the first bloom, coming in February, with the deciduous fruits in March and April, shortly followed by the oak and locust. Alfalfa, aThe altitudes and dates are those for the San Bernardino mountains and were fur- nished by Mr. G. D. Bullock, of Redlands. 978 UNIVERSITY OF CALIFORNIA EXPERIMENT STATION. the principal honey producer, commences to bloom about the middle of May and ends the latter part of September. Other surplus yielders are sweet clover and wild buckwheat, both commencing to yield in July. Those plants which help to some extent are grapes (pollen), catnip, horehound, golden road, ragweed (pollen), and Cleome lutea (yellow). During September and October rabbit brush yields a honey of a dis- agreeable smell and taste which is left on the hives for the bees to winter upon. FOOTHILLS OF THE SIERRAS. (F) In the lower portion of the foothills some eucalypti and the willow provide the first bloom, and higher up in the canyons it is the manzanita. This tree very often yields an extraction of a white-colored and delicious honey. Filaree, burr clover and fruit bloom follow in many sections, but the next honey plant of importance is the creeping sage. During favorable seasons it is reported to yield exceptionably well in Nevada and El Dorado counties. Minor spring and summer plants are mustard, wild onion, buckeye, birch brush, morning glory, milkweed, wild alfalfa, grease wood, and Spanish needle. The coffee berry (wrongly called Cascara sagrada) and the Christmas berry, with alfalfa, are the prin- cipal honey plants blooming respectively in May and July. Pennyroyal and " witch hazel" yield some honey in El Dorado County. Kern, Tulare, Fresno, El Dorado, Nevada, Yuba, and Placer are the chief honey-producing counties of this section. CENTRAL VALLEY. (C) In this valley bees continue to breed during the winter if kept in the vicinity of E. robusta (November to December) and E. globulus (December to January). The willow bloom follows shortly after. Next of importance are the deciduous fruits (almond, February 15th, others in March), followed by the orange (April 15-20 to May 15), filaree, burr clover, fiddle neck, tarweed and other spring flowers. When this bloom ceases a scarcity of nectar of about one month's duration exists, except in some favored localities where either the white or yellow sweet clover are found. This is relieved by alfalfa (second crop, the first not yield- ing), which begins to yield about the first week in June. It is the valley's mainstay, and continues to secrete nectar throughout the summer months, with the last month in the fall seldom producing any n ((tar. The fall bloom consists of four good honey plants, namely, jackass clover, blue curl, alkali weed, and spike weed. They all bloom on the plains favoring the poorer or alkaline soils, with the exception of blue curl, which is frequently found among the stubble of grain fields as well as in pasture lands. All vary greatly in nectar secretion, but usually when any one plant commences to once yield well, it will con- B'ULLETIN 217] HONEY PLANTS OF CALIFORNIA. 979 tinue to do so until the first nights of frost set in or up to the first heavy rain. Those counties producing the most honey are Fresno, Tulare, Kern, and Kings. MIDDLE COAST. (M) In December the willow, Cottonwood, eucalypti and mustard act as stimulators, and they are shortly followed by the manzanita, which usually yields a surplus. Other excellent honey plants are poison oak, barberry, black sage (main producer), and Christmas berry. In the mountainous regions of Monterey County, according to Mr. Gauze of Jolon, the manzanita does not bloom until March or April, and during May with favorable weather, Chia (an annual sage) yields a good crop, but usually the season proper does not commence until June, when the bees store honey from wild alfalfa, bastard sage and wild buckwheat (not a regular producer). During the past few years some of the best sage ranges have been supplanted by eucalypti and fruit trees. In September and October honeydew from the oak is gathered in considerable quantities. SAN FRANCISCO AND BAY COUNTIES. (B) During the winter, months bees breed well on eucalypti and acacia, the former often yielding considerable honey. In the foothills manza- nita provides the first nectar. Many of the spring flowers, with fruit bloom, furnish honey. They are filaree, burr clover, figwort, oak, poison oak, buckeye, mustard, locust and others. In the vicinities of cities and towns considerable honey is stored from garden flowers. The sage in the foothill regions of Alameda and Contra Costa counties occasionally yields an abundance of honey. During late summer and fall some horehound, tarweed and honeydew honey are often stored. The leading bay counties are Santa Clara, Alameda, Contra Costa, and Marin. NORTHERN VALLEY. (N) The season in the valley opens with pollen from the chickweed, acacia, poplar and willow, the latter sometimes yielding honey. The deciduous fruits bloom next, accompanied and followed by filaree, burr clover, mustard and other minor spring bloom. Between spring and summer there is usually a scarcity of honey, but in a few favored sections May weed, Napa thistle, and white sweet and yellow sweet clover yield some honey. During summer the bee pasturage consists of alfalfa, carpet grass, white sweet clover, smartweed, thistles, button willow (restricted), and some vegetable bloom, such as carrots, onions, asparagus and melons. Alfalfa and carpet grass continue to furnish honey during the fall. In 980 UNIVERSITY OF CALIFORNIA — EXPERIMENT STATION. the lowlands peppermint and blue thistle secrete nectar between June and November. In San Joaquin County considerable honeydew of inferior quality is gathered from the willow. On the plains, according to Mr. B. B. Hogabloom of Elk Grove, during a normal season are found yellow sticker (July 1st), tarweed (July 15th, with a flow lasting twenty days), and blue curl (August 1st). During winter the eucalypti furnish some honey. The principal beekeeping counties in this district are Sacramento, Yolo, Colusa, and San Joaquin. KLAMATH DISTRICT. (K) The first bee forage in the most northern region is again willow. It is soon followed by a variety of spring bloom, with filaree and burr clover predominating. At Yreka and other cities and towns the locust tree affords some honey. Both white and red clover are found near Edge- wood and Montague, from which bees are reported to gather honey. Considerable white sweet clover is not only present, but is rapidly spreading in almost all the regions of this district. It is a splendid honey yielder here. In Merrill, Shasta, and Scott valleys, and especially about Edgewood and Gazelle, alfalfa has proven the principal honey plant, with the second crop yielding the most. At Gazelle there is a yellow sage reported to yield a stringy honey, and Scott Valley reports another sage to be a honey producer. Some of the minor plants are a certain species of ceanothus, manzanita, tarweed, and turkey mullein. The common horehound is also represented in this district. CHART OF HONEY PLANTS. The chart below consists of an arrangement into groups based on the ability of the various honey plants to secrete nectar and can only be approximately correct, for the behavior of many such plants in the different localities, even during the same season, is so variable that a fair percentage of them would constantly need shifting from one divi- sion to another. The first group aims to include all those plants from which bees are known to gather a surplus amount of honey during an average season. In the second group are found those which only under very favorable climatic conditions will secrete enough nectar to make an extraction of honey possible. It also includes that flora which greatly stimulate bees to breeding and to "fill up" for winter. The last group contains all plants which bees are known to frequent, and which are not already mentioned in the two above divisions. Most of the plants listed in this group are only visited by bees during unfavorable seasons or where honey-producing plants are scarce, and do not, generally speak- ing, secrete nectar in sufficient quantities for the bees to store.

Honey water-white, mild in flavor, and of good body, granulates in three to six months, when it much resembles a paste made from powdered sugar. The very fact that it is spreading so rapidly over the poor lands of the San Joaquin Valley, and that it produces the only water-white honey, with the exception of blue curls, as far as the writer knows, that is produced in the late fall, has led to the conclusion that jackass clover will be one of the greatest honey-producing plants of this State, and may, in the future, rank next to sage and alfalfa. During the fall of 1909, a Fresno beekeeper reported that he extracted 30 pounds per colony each week for six weeks from this source. Another beekeeper of the San Joaquin Valley relates that during a jackass clover flow the noise was terrific, and that home-coming bees flew so slowly that they could be picked out of the air. It was Henry T. Chrisman of Coalinga, who first became aware of its value as a honey plant, and gave it its present name. Resedace^e. Mignonette Family. Eeseda odorata L. et lutea L.

Introduced : wide range ; interior valleys, foothills of the Sierra, and through the Coast Range. March. Honey and pollen from the flowers. Perhaps the best honey producer of deciduous fruits. Warm weather at blossoming time usually means an extraction of pear honey accompanied with swarming. There is no doubt that the honey bee is the principal agent in the distribution of pear blight, but should she be excluded other bees and insects are quite capable of spreading the disease. Pyrus malus L. et var. Apple. Introduced: throughout the Coast Range, especially in the Pajaro Valley ; southern California, and in the low lands of the Sacramento and San Joaquin valleys. March.

T. Clarke of this station contends that one colony is amply sufficient to fertilize 80 acres of apple bloom, and that other bees and insects aid greatly. Editor Root, however, believes that ten colonies might pollenize a ten-acre orchard, "but probably 50 or 100 would be much better."14 13Wickson, E. J. California Fruits. The Pacific Rural Press.

Alfalfa. Lucerne. Introduced: under cultivation in most valleys throughout the State. April-October. Honey water-white, white, light amber and amber, according to local- ity, character of the soil and season of the year; of excellent body and granulates within a few months after extraction. Alfalfa, due partly to irrigation, is the most reliable honey plant of California. In those years when the Coast ranges do not receive sufficient rainfall, the output of alfalfa honey exceeds that of the sage. The San Joaquin and Imperial valleys are the two leading alfalfa honey districts. In the former, the first and last crops yield little if any honey, but the second and third, when proper climatic conditions prevail, give up a great abundance of nectar. Mr. J. T. Dunn of Fresno says that four or five days of hot weather and little or no wind, in the early part of June, will "bring out" the nectar, and insure a flow, whether or not wind or cooler weather comes later. In respect to the influence of the soil on the color of the honey, it appears that alfalfa grown on sandy soil which does not hold water will produce honey light in color, but in many por- tions of the valley where alluvial soil prevails, and, where water is within four to eight feet of the surface, the color of the honey is decid- BULLETIN 217] HONEY PLANTS OF CALIFORNIA. 999 cdly amber. In the Imperial Valley the flow is constant except that sometimes the first crop is a little light. Both these districts report that the color of the last extraction of honey is perceptibly darker than earlier extractions. In the Sacramento Valley considerable honey of excellent quality is procured especially when either the second or third cutting of alfalfa is allowed to go to seed. Mr. Thos. J. Mumma of Dun- nigan states that alfalfa grown on light, sandy soil produces a pure white honey while that grown on heavier soils is slightly amber in color. Alfalfa fields along the coast do not yield sufficient nectar to make it worth while to the beekeeper. The miller and grasshopper often decrease the flow from the third crop in the San Joaquin Valley, whereas the alfalfa butterfly (Eurymus eury theme) causes a loss to the beemen of the Imperial Valley. ^Melilotus alba Lam.

Phaseolus lunatus L. et var. Lima Bean. Introduced: cultivated principally in Santa Barbara, Ventura, Los Angeles, and Orange counties. July- August. Honey, water white, heavy body and very delicious flavor. The Ventura bean fields produce most of our lima bean honey. Cool, foggy weather preceding bloom, with sunshiny days following appear to be ideal conditions for nectar secretion. The first two weeks of bloom are the best, and as much honey is secured then as is gathered during the following four weeks of what is known as the ' ' after-bloom. ' ' Towards the last of the flow the honey darkens noticeably. Some years the lima bean louse does considerable damage to the maturing buds, thus destroy- ing some of the first blossoms.

B'ULLETIN 217] HONEY PLANTS OF CALIFORNIA. 1003 RuTACEiE. Rue Family. Citrus acida Hook. Lime. Introduced : grown occasionally throughout California. Blooming period varies. Honey from the flowers. Citrus aurantium L. et var. Orange. Introduced: cultivated in the Sacramento and San Joaquin valleys, but principally in southern California. March-May. Honey, water white, of heavy body, exquisite aroma and superb flavor : granulates within a few months after extraction. Yet beekeepers of Lindsay and Portersville report that it does not granulate for one or more years. It is more constant in the secretion of nectar than is the sage. The largest crops are in the neighborhood of Riverside and Red- lands. To quote Mr. McNay of Redlands: "Four years out of five orange has yielded a fair crop, so I have been able to select and ship one or more carloads of pure orange bloom honey each year, except 1904. "18 "The scale hive showed that nearly all orange honey was secured in about five hours of each day, from eleven to four o'clock.19 Very warm weather often produces unusual nectar secretion in such abundance that it is impossible for the bees to gather all of it. Mr. R. K. Bishop of Orange County has observed that the bees pay no attention to the large globules of nectar on the leaves, but go direct to the bloom, and it is his contention that the nectar in the bloom is much more con- centrated. Citrus decuman a L. Grape Fruit. Pomelo. Pumelo. Shaddock. Introduced: grown in similar situations as our other citrus fruits. Blooming period varies. Considerable honey from the flowers, but not the equal of either the orange or the lemon. Citrus limon L. Lemon. Introduced: cultivated principally in the coast regions of southern California. Blooms all seasons of the year. Although a valuable honey plant, it does not yield as well as the orange. This may be partly due to the proximity of lemon orchards to the coast, for, orange trees grown in similar regions do not secrete as much nectar as those of the interior valleys — a climatic factor. (A more striking example of this will be found in the case of alfalfa.) Citris nobilis Lour. Mandarin. Kid Glove Orange. Introduced: not common; cultivated occasionally in different parts of the orange belt. Blooms a little later than the above. Honey from the flowers. lsGleanings in Bee Culture. July 1, 1906.

In the fall where honey-producing plants are scarce, the bees often gather and store considerable quan- tities of grape juice when the fruit becomes punctured by other insects or birds. This juice sometimes ferments in the cells and causes dysen- tery among the bees. 1008 UNIVERSITY OF CALIFORNIA — EXPERIMENT STATION. ' TiLiACEiE. Lime or Linden Family. Tilia americana L.

One of the leading honey plants of the Sacramento Valley, com- mencing to yield about the middle of May, and lasting till frost. If the coast beekeepers are anxious for bountiful rains, it is not so with their Sacramento brothers, for, the earlier the Sacramento River recedes, the sooner are the slopes of carpet grass bordering the river drained of all excess water, a condition which means a sooner and better flow of nectar. Three fourths of the honey output of Sutter County is reported to be from carpet grass. Mr. J. J.

Coast ranges and ascending to 5,000 feet in the San Bernardino mountains. March- June. (Audibertia stachyoides Benth.) San Diego County, February-May. Honey, water white and of a rich and delicious flavor ; of heavy body especially north of San Luis Obispo; does not granulate; moderate amount of yellow pollen. This is the best honey producer on the coast, the flow being dependent upon winter rains with a warm spring quite free from cold winds and fog. When in bloom a certain amount of warm weather is required before it will produce nectar. As a general rule, every fifth year an excellent crop is obtained, and every third or fourth year a total failure is experienced. That which is commonly known as "California White Sage Honey" throughout the United States and Europe is not from the white sage, but the black sage. The white sage yields comparatively little honey as compared with either the black or purple sage. The sage worm, in cloudy weather, often becomes abundant enough to destroy much of the bloom. Dodder and a rust (Puccinia) also do damage in certain localities. There is a cross between this species and 8. apiana. For the correct botanical history of the melliferous sages, see H. M. Hall, Pacific Rural Press, February 22, 1908. * Salvia sonomensis Greene. Creeping Sage. Ramona. "Montana species at middle altitudes, Ramona, mountains west of Calistoga, Mt.

In Sacramento County, however, Mr. B. B. Hogaboom reports this thistle to yield a honey light amber in color, of good flavor and fair body from May 15 to June 15. It abounds on the sage ranges of Ventura County, but has never been known to yield any nectar there. *Centromadia pungens Greene. Spikeweed.
