INTRODUCTION The name Orchid is with most persons associated with the heat and luxuriant vegetation of southern climates, and our North American species are, as a rule, known only to botan- ists. Few in number, terrestrial in their habits, often un- obtrusive in color, almost valueless in trade, they make of themselves no claim to distinction in the vast floral tribe to which they belong ; and the rambler in wood or field is sur- prised when told that this or that flower he has brought home is related to the gorgeous and curious plants he has admired in some hot-house. When the Island of Java contains over three hundred species of Orchids, it is but a confession of poverty to state that the section of the United States lying east of the Mississippi and north of North Carolina and Tennessee pro- duces fifty-nine species and varieties ; but when this area is narrowed down to New England and forty-seven are found in the catalogue of her flora, the provincial pride that devotes a special treatise to this little group can be easily understood. My own acquaintance with this rural family was for years what might be called a bowing one ; a supposed ability to call its members by name when I saw them and an appreciation of their outward beauty or oddity forming a superficial knowledge with which I was quite content until I began to make a series of sketches of my charming friends. Then, as I observed them more closely in their homes, I realized how little one knows about .his neighbors, after all ; discovered that there were brothers and sisters, cousins once or twice removed and other relatives I had never seen, and that these apparently 6 IN TR OD UC TION. guileless folk had tastes and passions deserving the closest study. They actually seem, now that I understand them bet- ter, more like human beings than forms of vegetation, and if we believe the marvellous tales of the wise men as to the de- pendence of Orchids upon insects; that each part of a flower has its share in the mutual labor ; that the spots and fringes, silken curtains and waving banners, strong, or subtile odors, are not mere adornments, but necessary to the fertility of the plant and the perpetuation of its race ; that there are changes in color and structure, plots and devices to gain their ends, we must confess, I think, that although the Orchids do not spin, they toil with a wisdom and foresight that Solomon might have envied. It is well to enumerate at this point the leading characteris- tics of Orchids ; that is, of the Orchis family, and I find that many are puzzled by the interchange of words. Our Orchis spcctabilis is a species of the genus " Orchis" but the Orchis family has many other genera, and while it is proper to call an Arethusa or a Lady's-Slipper an Orchid, it is not proper to call either an Orchis, that final consonant being of decided impor- tance in the botanist's view. Quoting from both Gray and Darwin, let me explain that the flower of an Orchid has " 3 inner divisions (petals) and 3 outer divisions (sepals) mostly of the same texture and petal- like appearance. One of the inner set differs more or less from the rest and is called the labellum or lip," and this is often beautifully or grotesquely shaped, and whether furnished with a spur-like appendage or destitute of one, it is almost always a conspicuous feature. " It is by far the most impor- tant of the external envelopes of the flower. It not only secretes nectar, but is often modelled into variously shaped re- ceptacles for holding this fluid, or is itself rendered attractive so as to be gnawed by insects. Unless the flowers were by some means rendered attractive, most of the species would be cursed IN TROD UCTIOJV. with perpetual sterility. It is often deeply channelled, or has guiding ridges," .... often approaches the other divisions " closely enough to render the flower tubular." It is properly the upper petal, but a slight twist in the ovary or seed-vessel has turned the flower upside down, a change enabling insects to enter the flower more easily. " In most flowers, the stamens, or male organs, surround in a ring the female organs, called the pistils. In all common Orchids there is only one well-developed stamen, which is con- fluent with the pistils and they form together the column. Ordinary stamens consist of a filament or supporting thread (not always seen in the Orchids) which carries the anther" and this is " a sort of case filled with a waxy or meal-like powder, called the pollen, which serves to fertilize the pistil." " The anther is divided into two cells, which are very distinct in most Orchids, and appear in some species like two separate anthers." " Orchids properly have three pistils united together, the upper and anterior surfaces of two of which form the two stigmas. But the two are often com- pletely confluent so as to appear as one." The grains of pollen, when de- posited on the stigma, " emit long tubes," and these penetrating the sur- face, " carry the contents of the grains down to the young seeds in the ovary," which, when mature, is " a i-celled, 3-valved pod, with innumerable minute seeds appearing like fine sawdust." " The upper stigma is modified into an extraordinary organ called the 7'ostellum, which in many Or- chids presents no resemblance to a true stigma. When mature, it either includes or is altogether formed of viscid matter." Fig. 2.— Section of the Flower of an Orchid. (From Darvvin.)

Originally, Darwin tells us, the flower consisted of " fifteen organs, arranged alternately, three within three, in five whorls or circles ; three sepals, three petals, six anthers in two circles (of which only one belonging to the outer circle is perfect in all the common forms) and three pistils, with one of them modified into the rostellum. Of the existence of three of the anthers in two of the whorls, R. Brown* offers no sufficient evidence, but believes that they are combined with the labellum whenever that organ presents crests or ridges. The amount of change these flowers have undergone from their parental or typical form is enormous. Organs are used for purposes widely different from their proper use, — other organs have been entirely suppressed or have left mere useless emblems of their former existence." Two stamens belonging to the outer circle, that were or became petal-like, have united with a real petal to form the lip. Seven organs have united to form the column," of which three alone perform their proper function, namely one anther and two generally confluent stigmas, — with the third stigma modified into the rostellum and inca- pable of being fertilized, — and with three of the anthers no longer functionally active, but serving either to protect the pollen of the fertile anther, or to strengthen the column, or existing as mere rudiments, or entirely suppressed. To trace the gradations perfectly between the several species and groups of species in this great and closely-connected order, all the ex- tinct forms which have ever existed along many lines of descent converging to the common progenitor would have to be called into life." f The flower of an Orchid may be solitary, or one of a cluster, and is furnished with a bract, a kind of little leaf that springs from the point where the flower stem joins the main stem. Sometimes petals and sepals unite to form a hood or roof over * A noted authority on this special subject, f "The Fertilization of Orchids." IN TROD UCTION. 9 the lip \ sometimes spread apart, giving the blossom the look of a winged insect. Who knows but nature intended to make the resemblance closer and then changed her mind ? The blossom or blossoms may be borne on a scape, a stalk without normal leaves, like that of our Pink Lady's-Slipper, or on a leafy stem like that of the Yellow Lady's-Slipper; this scape, or stem, being sometimes covered with minute down ; often ribbed or angled. The leaves are parallel veined, like those of the Lilies (indeed, as the Lily family follows the Orchis family pretty closely in botanical order and there are obvious points of resemblance, it is not strange that some Orchids are mis- taken for Lilies), and coming to the roots, we have three or four kinds; clusters of fibres, clusters of tubers, branching, coral-like substances, and bulbs. Nearly all Orchids, wher- ever they may grow (in England, all but one species), de- pend so closely upon insects for their fertilization that the failure of a plant to attract the insects that would naturally visit it, or to produce the nectar for which they come, would work a two-fold mischief: the extinction of the one must be followed by the extinction of the other. To sum up, in the words of Hermann Miiller: " The Orchis family is remarkable for the following characters, due to its wide distribution and to its enormous number of species : first, for great variety of habit and diversity of station ; secondly, for its immense variety of peculiar and highly-specialized flowers ; and thirdly, for the unusually large number of seeds produced in one capsule." * Of our North American Orchids, ten species are identical with those found in Europe, and several are represented either directly or by allied forms in Darwin's " Fertilization of Orchids." This writer, in his descriptions, and Professor Gray, in his observations on American species,f have told their fas- cinating stories so clearly that it would not be necessary for * " The Fertilization of Flowers." \ See appended Bibliography. IO INTRODUCTION. me sometimes, in quoting from both authorities, to strip the paragraphs I have interwoven still further of their technical language, if it were not partly my aim to attract those well dis- posed readers who are ordinarily discouraged by the sight of a long array of mysterious words. I hope that enough descrip- tive terms have been taken from Gray's Botany, to furnish what would not be obvious from an inspection of the illustra- tions, and that the abridgment of quoted passages and the re- jection of details has not been carried too far. It should be added that terms such as " front," " outside," " lower," etc., are not always used in the strict sense in which they are em- ployed in the botanies. How well worthy of minute examination this single family is, is proved by Darwin's modest confession after twenty years study, that he doubted if he thoroughly understood the con- trivances in any one flower. This has a discouraging sound, at first ; for the possibility of discovering anything that eluded his eyes, keen as those of the hero of a German legend, may well be questioned ; but the field is a tempting one to glean, and as few investigations have been made in America, judging by the scarcity of printed matter relating to the subject, our humblest species still mocks us with its secrets. In speaking of the Orchids found in New England I shall arrange them in the order in which they blossom in the vicinity of Burlington, Vermont, where most of my own observations have been made, and shall hope to make my calendar service- able elsewhere, as my arrangement agrees pretty well with lists sent me from other sections. Specific dates are worth con- sidering, it seems to me, although one cannot rely on them, but as a safer guide, especially for those who travel during the period when these plants are in flower, let me say that so far as I can learn, a plant blossoming in Southern Connecticut about the first of any given month would be due in Western Vermont, or the upper Connecticut valley between the ioth IN TROD UC HON. 1 1 and 15th, and in the White Mountains, two weeks later still; that is, in low or moderately elevated land. Between Portland, Maine, and Moosehead Lake, there is thought to be a differ- ence of at least two weeks in plants that bloom in spring; *• this difference lessening as the hot weather comes on." The amateur collector will find that it makes a good deal of differ- ence in point of time, whether his search is made on the north or south side of an elevation ; whether in shaded or open ground ; and, moreover, will often discover that the county map on which he has relied is of little use in locating " stations," for he can never be sure that the plants he has seen in one swamp will occur in a corresponding swamp in the next township ; and, indeed, it is highly probable that species abundant on one side of a mountain range will en- tirely disappear when he reaches the other side. In the case of Eastern Massachusetts, to give a clearer illustration, cer- tain Orchids grow within thirty miles of Boston, but one's success in getting them depends chiefly on whether he meas- ures the thirty miles north or south of the city. The subtle influences of soil and climate sometimes contradict one's learned conjectures very unpleasantly. I am indebted to Professor Gray for permission to make liberal extracts from his Manual, to Rev. Henry P. Nichols of New Haven, Conn., Dr. N. L. Britton of Columbia Col- lege, and especially to my friends Henry H. Donaldson and Frederick H. Horsford, to whom this work is informally dedi- cated. ORCHIS FAMILY IN NEW ENGLAND.
