ILLUSTRATED WITH 438 FIGURES LONDON HARDWICKE & BOGUE, 192 PICCADILLY 1877 PREFACE. LAST YEAR I laid before the Linnaean Society a Paper on Pollen, with drawings of the various kinds. But it having been brought to my notice that several German botanists had written on the subject of late years, and also that HASSALL had published an important paper on it, I withdrew mine from before the Society. Since then I have altered it considerably ; having added new matter, and omitted from the plates what had been figured previously by HASSALL and ROMANOFF, except where I differed from them. I also take notice of the drawings by Mr. WORTHINGTON SMITH, which were published by him after my paper had been laid before the Society ; and have added to the list all that have been figured and noticed by former botanists on the subject ; so that it may be viewed immediately in detail. I trust that, thus altered, this paper may prove a not unimportant addition to our knowledge of the subject. POLLEN. Two years ago Mr. Airey published some interesting facts about the dust collected on smeared plates of glass, and mentioned that some of the dust was pollen. I began ac- cordingly to enquire into the forms of pollen likely to be found in such places, and from this went on to discover all that I could about pollen. I had many years ago drawn a number of specimens, but I now took to examining them more closely, and drawing them to scale. The principal papers already published on this subject are by 1. Purjinke, in Latin. His illustrations of the cells of the anther are very interesting, but unfortunately, the pollens drawn have been treated with water, so as to lose most of their distinguishing marks. 2. By Mirbel, in French. Accurate as far as they go, but on too small a scale. (f Siemens de Physiologie vegetale,' 1815.) 3. By Fritzsche, in German (1832). Most beautifully drawn both in the simple form and under oil, and under the effects of weak sulphuric acid. He examined almost all the natural families. 4. By Hugo Mohl, in German, translated into French in the 'Annales des Sciences Naturelles.' He goes most thoroughly through all the families in the natural state of the pollens, or as they appear under olive oil or water ; drawn to scale. I have followed in his footsteps ; and now I wish to point out a few inaccuracies into which he has fallen, and to carry on the examination of the other plants. 5. Hassall reviewed Mohl, showing some differences, and 2 POLLEN. going through all the natural families in detail, with numerous plates drawn to scale, and published in the 'Annals of Nat. Hist.' 1842, vol. viii. ix. 6. Lindley published figures of pollen after some of the above authors ; and 7. A further republication of them in the ' Micrographical Dictionary.' 8. Since that time Herman Schacht has published some beautiful drawings in the ' Jahrbuch der Botanik,' Berlin, 1860, ii. p. 109. I agree very much with what he has published, except about the Pinus family, of which his descriptions differ from what I have observed, and from the drawings of Mohl, and Hassall, and Dr. Hooker. 9. Nagilihas also a paper in the same publication, vol. iii. Eosanoff has a paper in the same publication (1865), vii. p. 34, principally on the pollen of the Acacise. 10. Leursen, in vol. vii. p. 34 of the same publication, reviews a paper by 11. M. Pollenden, Bonn, 1867; 12. A paper by Mr. A. W. Bennett in the 'Popular Science Eeview,' April, 1875 ; and lastly, 13. Some woodcuts by Mr. Worthington Smith in the * Gardener's Chronicle ' in October last ; republished in the 'Microscopical Journal,' January, 1877. The pollen forms are often noticed by Dr. Hooker in his large works, and also by some foreign botanists in the Brazil Flora. It is remarkable, that while in some families the species vary greatly, in others they are almost always the same. Some may therefore be considered normal ; others as having only a specific value. The different size of the grains is also marvellous : some very large, and visible to the naked eye, as in Stachytarpheta, the Malvacese, Cobsea, Pan- cratium, and some species of Iris, reaching as much as -^ th of an inch; while others, as many Boraginese, Primulaceae, Me- lastomacese, and Saxifragese, are as small as |00°0 ths of an inch. In colour also they are very various, but usually some shade of yellow or white; but I have observed blue, red, brown, or rarely green, which has been denied by Lindley. POLLEN. 3 Mr. Bennett would divide the pollen into those which are wind-borne, or anemophilous, and those which are not so scattered, or entomophilous ; but the grains are by no means all globular, as he there asserts. The Graminese and Cyperacese are usually prismatic. The Populus has globular pollen, while the Salix, in the same family, is somewhat cylindric, as is that of Rheum, which is probably anemophilous, and the dioecious Rumices, with three slits. Plantago, which appears to be also anemophilous, varies from a polyhedric to the simple form, while the wind-borne pollen of the Coniferse is very different. The Urticse are very small and elliptic, with three slits, withering into a prismatic form. The Grasses and Cyperacese, and perhaps the Plantagineae, are without the sticky nature of the outer coat, which obtains through all other pollen grains. Some grains throw out a quantity of tubes, by which they are hung together, as in Richardia cegyptiaca, Strelitzia regina, and the Rhododendron, &c., but more usually they are quite distinct. I omit any account of the peculiar pollen of the Asclepiadese and Orchidese, which have not common loose grains of pollen, but joined together in a coherent mass. I also do not intend to make any remarks as to the struc- tural nature and function of the fovilla and the pollen grains. I have found but three or four instances in which the same anther produces two or three forms of pollen ; usually they are all similar, often with some small or imperfect grains ; but in the Mimulus luteus I have found the simple form, common in the Scrophulariacese, mixed with the coiled form, which H. Mohl pointed out in the Mimulus moschatus. [ have not been able to find this coiled form myself in the latter, and Mr. W. Smith considers it an error of H. Mohl's ; but in this he is doubtless mistaken, for I have found it in the next species, M. luteus (No. 138). I have also found many forms of pollen in the Browallia elata (No. 146), in the same anther, but not in the coiled form ; and H. Mohl mentions others also which I have not had the opportunities of examining. I find also two forms in Thalictrum flavum and glaucum (Nos. 429-432), probably also in Ranunculus auricomus, as remarked by Hassall and myself in the Anisogeisos. B 2 4 POLLEN. The simplest form is a bag with one slit, from which the fovilla escapes, then opening out into a hat-shape, like many of the Liliacese and Amaryllidese. A similar form is seen in the Magnolia and Nuphar — a simple slit. It is curious that the simplest pollen should be found in one of the most ornate and largest of flowers ! This simple form is often found with ornate markings on the outside, in the Liliacese, for instance. The next simplest form looks at first the same, but on examination it is found to contain three slits or three bands, the bands more or less broad. When floating in olive oil, so that all the sides of the grain are shown, the end is usually somewhat three-cornered, being the ends of the three slits or bands. This is universal, as far as I have seen, in the Saxifragese and Crassulacese, and almost universal in the Rosacese — (the Poteriese (Nos. 286-7) and Spirsea palmata (No. 285) are the only exceptions I have seen. Hassall men- tions another form with four slits in Rubus, but what I have examined had the usual simple form) — the Scrophulariacese, with the exception of Mimulus, which has three forms, and Browallia, which has many forms ; most of the Solanaceee, and all that I have examined of the Melastomacese, are similar, but are the smallest I have seen of this form. It is found in many other families, in which, however, there are also other forms ; as in some Ranunculacese and Sapindacese, and in Spergularia rubra (No. 360) alone of the Caryophylla- ceae. The Primulaceae have usually three slits, and when seen end up the pollen looks trigonous ; but in some cases they have four or six slits, as remarked by Mr. A. W. Bennett in the 'Nat. Science Review' of 1875. P. cortusoides (No. 189) is both simple or trigonous, as I have examined, and as described by Mohl. Mohl and Hassall both describe the pollen of the Graminese as sub-globular, with one pore ; but I have examined numerous specimens, and find it (with the exception of the Panicese, of which I have but seen two) always of one peculiar type — of a somewhat prismatic, form, with rounded ends, larger at the top, and smaller at the bottom ; while there are four sides with an oval or round opening in them, occasionally 3-sided, 5-sided, 6-sided (No. 104). Mirbel describes the Phleum as I have observed it. Mr. A. W. Bennett describes this form in Briza, but says the Dactylis is POLLEN. 5 oval ; but I think he cannot have floated it in oil, or he would have seen the same form as in Briza. I fancy that Mohl and Hassall chanced merely to see the upper side. Arundinaria, Lagurus, and Pogonatherum have a 6-sided prism, as represented by Mr. W. Smith. The only Panicum I have examined is P. plicatum (No. 5), which is quite dif- ferent from any of the other Graminese, being globular with three pores ; and there is something of the same kind in Streptium, a S. American genus of the same sub-order. The Cyperacese have two forms — one like a drop of water (in Cladiuin and Scirpus) ; in Carex it is somewhat prismatic, with a pore in each facet, which is the form of the Juncacese. Drimopsis in that family is peculiar, like a tooth, a deformed crystal of the Carex type (No. 23). To return to the more banded forms. The Papilionaceae have generally three broad bands; when seen endwise the pollen looks trigonous (the Erythrina and Indigofera have really a trigonous form, not cylindrical). Some are broader than others, but of a similar type, which obtains also more or less among the Csesalpiniese, with the exception of the Bauhinia, which is of a very different type, large and spheri- cal, and echinulate, or large and trigonous. The Acacieae are (with the exception of Mimosa pudica and in a few species) composed of nine to twelve or sixteen cells, in squares or pyra- mids, or cubical arrangement. The Cruciferae have also three bands, smooth or rough, usually containing much oil, which is diffused in the olive oil. Schizopetalus is rougher, very richly marked, with no distinct slits (No. 385). Mr. Bennett has remarked the globular form of Pringlia, but it is possible this form has been assumed after being examined under water, or having been preserved in spirit. The Apocynacese, Jasmineae, and Rutaceae, in general are 3-banded, often with rich ornamentation on the outer coat, and containing much oil, which is diffused in olive oil, as is also the case with the very oily Tiliaceae. Adenandra fragans, in Rutaceae (No. 315) has two forms, one slightly curved, the other having an additional coat across the lower one : this is also found in the Umbelliferse, which have also three slits, but are gene- rally constricted in the centre. There are several forms of trigonous pollen. The Myrtacese, as far as I have observed, are all the same ; the Proteaceee (except Banksia, which has 6 POLLEN. two instead of three pores at each end) ; many of the Ver- benacese, as Verbena (No. 105) and Lippia; while Stachy- tarpheta is of large size (j^thof an inch), with its three pores, containing large craters, figured by Fritzsche and Hassall. The Hydrophyllacese, and most of the Cucurbitacese, finally, the very large Onagracese, which are well known and described, also are trigonous, but in that family some of the Fuchsias (F. thymifolium) have but two pores, like Banksia ; and Epilobium roseum is compound, as described by Hassall. The Dianella, Stypandra in Asparigineai, are also trigonous, but in a very different nature, having a single cell with the slit, so as to make a cocked-hat form, not with a pore in each facet, as is the case in true trigonous pollen. Many have polyhedric pollens, each part having a pore, sometimes smooth, sometimes echinate, as many Polygona, the Caryophyllacese, Amaranthacese, Chenopodiacese, and Alisma (No. 31). Many are globular ; some simple, as Canna (No. 46), Costus, Musa (No. 45), Strelitzia ; some smooth, some echinate, as Crocus* (No. 38), and Philesia (No. 15), which are richly echinate, and the Potomagetons. Some of the Nymphacese are echinate, as Nelumbium (Nos. 400-403) and the British species of Nymphsea, but the foreign are simply 3-banded (Nos. 401-2). The Passiflorese, with large pores, are beautifully portrayed by Fritzsche. The most ornate are among the Synantherese, most of which are poly- hedric or echinate, oval or globular, with three or more pores in them ; a few are 3-slitted, as Artemisia (No. 213), and some Centaurese (No. 218), and the Mutisacese (No. 209). The Malvaceae have large pollen, and many of the Con- volvulacese; Cobsea and Mirabilis are among the largest I know, and Cucurbita is one of the most beautiful (figured by Fritzsche and Hassall and Pollenden, and well drawn by Bauer, in the British Museum). Some of the Clerodendrons are globular, others nearly square. Some of the Caprifolaciaceae and Bubiacese are globular ; but they have many other forms, some large, some * In the genus Crocus, which always is globular, some species are quite smooth and shining, others more or less echinulate ; while in C. mceaiavus, according to Mohl, and in C. nivalis, the outer coat is spiral ; but it disappears in water, the extine being thus invisible. POLLEN. 7 very minute. Diph ylleia in the Berberidese is echinate, while the greater part of that family is smooth and globular; others (Epimedium) have three bands; many others in the Malpighiacese are globular, with pores on the equator, or variously disposed. Similarly in the large genus Kanunculus. R. arvensis (No. 425) alone is echinate ; most of that species have three bands, while many of the Anemone have also three slits or bands ; A. coronaria (No. 424) is dodecahedric, and A. pavonina (No. 425) is dodecahedric, and has rough globes, not however echi- nate. Many of the Dipsacacese are also sub-globular, but some have fantastic forms: the Morina is like a spigot (given by Mohl, and observed by myself in Indian specimens). Some of the true Campanulacese have pollen covered with small echinations, which disappear in oil; others are smooth, while the Lobeliacese are all small, with three slits. In the sub-order of Epacridese, Styphilese is echinate, while the true Epacris has compound pollen like the Ericaceae. The true Geraniese sub-order is large, rough, or sub-echinate, and the Viviana is similar, but smaller. The Tropseolum has usually three bands, which assume a trigonous form when seen endwise, as figured by Pollenden ; but one species, Tropceolum tricolor, is very different (No. 327), a curved narrow form, not very far from the peculiar crescent shape of Limnanthes (Nos. 329, 330) ; another species of Limnanthes is figured by Hassall, somewhat similar, but echinate. Balsa- minese are somewhat oblong, with three bands or little pores, and the Oxalidese are usually globular or oblong, smooth or rough. The Boraginese generally have the pollen in the form of a dumb-bell, but some are of the more common 3-slitted form, or oval. The Polygalese have a peculiar form ; in the natural state oval with narrow bands. When made more visible by olive oil they show a beautiful form like a wicker- work basket, varying slightly in the different species. Some of the other genera are not similar, but of a simple form (Nos. 367, 368, 369, 380). The Papaveracese have many forms, some simple, some globular ; some of the Fumariacese are very peculiar, cubical, with large pores (Fumaria officinalis), figured by Hassall. The Violacese, as remarked by Mr. Bennett, are penta- 8 POLLEN. gonal, having five bands (four in Hassall's drawing) ; while F. odora (No. 375) and cornuta (No. 376) have three small slits. A garden hybrid between V. tricolor (No. 370) and V. cornuta, called Perfection (No. 377), shows some of the characteristics of both parents. This is very remarkable, as Mr. Worthington Smith has pointed out that it is impossible to cross species which have different pollens ; but this does not seem to be the case at any rate. No doubt the subject will be carefully examined by hybridists, to whom it is most important. The Pinus and Abies (No. 37) have a very peculiar form ; two grains of pollen connected as it were by a broad band. This is distinctly shown by Mohl or Hassall, and confirmed by my own observations. I mention this as Schacht describes them differently, and I cannot but believe him mistaken. Dr. Hooker describes some in his Tasmanian Flora somewhat similar, but with three instead of two grains of pollen. Other Gymnosperms are quite different, sub-globular, with four coats ; in water or acid they burst at one side with a large opening. Some are quite simple, as Ephedra, or the Cycadese (No. 47). We have, further, several compound pollens, three or four cells united into one, as in Ericaceae (with the exception of Clethra, which has the common 3-slit form), Epacris, Randia longiflora, and a few other Rubiaceae. Epilobium roseum in Onagracese, Salpiglossis atropurpurea in Solanacese, and Lechenaultia in the Goodeniacese, mentioned by Hassall, are also fourfold. We also find some in groups of four, but not so completely united ; as in Beschorneria, and a specimen of Fourcroya, mentioned by Schacht. The other Agaves I have examined are simple. Typha (No. 26), Cytinus (No. 57), are also 4-celled. The Acacieee are many-celled, nine to sixteen cells united in cubical or sub-trigonous forms. The Acanthacese are perhaps the most beautiful of all, in many forms : some in a peculiar coil, which can be unwound ; some in an oblong coil ; some not coiled, but richly marked ; some spherical (No. 108-127, P. vii. viii. xix.) ; examined in the ;j~inch objective, occasionally in the 8th objective. I here offer my thanks to Dr. Hooker for allowing me to collect pollen in the Kew Gardens, and to Mr. Oliver for permission to collect it on some dried specimens, and to Dr. Murie for his valuable assistance. POLLEN. 9 The accompanying list of plants shows those of which the pollen has been described. Those marked with an aste- risk I have myself examined and measured. Opposite the name of the plant is the size 60°00 ths of an inch, measured by the micrometer. The authors who have examined pollen are : Purjinke (P.), in Latin.

According to Mohl, they are 'oval, shining, not viscous, finely grained, with a punctiform pore and a narrow halo.' Hassall says, ' granules separate, circular at first, but on the emission of a single pollen tube, with which each grain is furnished, generally be- coming ovoid.' Fritzsche describes the pollen as having a valve to the pore. I find them somewhat prismatic, tapering at both ends, rounded, one smaller than the other, without viscidity. I have been unable to detect the pore. I have examined many species, but find only three which are not prismatic, which are the only species of the Paniceee which I have examined. The pollen flies off so rapidly on the opening of the anthers, that we must secure the pollen as the anthers open. OryzecB. *0ryza sativa, 6. Zizania aquatica. H. Phcdaridece. *Zea Mays, 20. 23.
