PLATE XXV. Route of the "Utowana" Limits of the Antillean Flora PLANT/E UTOWAN/E. CHARLES F. MILLSPAUGH, M.D. Mr. Allison V. Armour, of Chicago — through whose generous patronage the author made his first collection in Yucatan for this Museum during December, 1894, and January, 1895 — wishing to advance the knowledge of the flora of that peninsula and to afford the opportunity of correlating its vegetation with that of the coastal region of the Greater Antilles, again planned his winter cruise in 1898-1899 that it might embrace as many as possible of the more important points at which the study of the question could be profit- ably conducted. He therefore placed his new auxiliary steam sail- ing yacht "Utowana" in commission, and invited Messrs. Jordan L. Mott, Jr., and Edward S. Isham, Jr., of New York, and Mr. Edward P. Allen, photographer of this Museum, and myself as his guests. THE ITINERARY. December 21, 1898, was set for sailing, but, delayed by the memorable fog that hung over the east coast during the 21st, 22d and 23d, departure was not taken from the dock at the foot of West Thirty-fourth street, New York, until eight o'clock on the morning of the 24th. The wind, which had been in the west during the morn- ing, fell in the afternoon, and using steam a course was laid from Sandy Hook for the Bermudas. During the evening and night a gale came up out of the southeast, and the next two days were spent beating against the wind and fighting the cross-sea of the Gulf Stream in weather so gloomy that satisfactory observations could not be made. Trusting to a faulty sight rather than reliable dead-reckoning, our captain missed the islands to the southward, and noon on the 27th found us sixty miles to the eastward of our intended port. As we came about, the wind, with Atlantic perver- sity, also shifted into the west, and we were compelled to fight our way back against even rougher water than before. During the mid- night watch the seas broke over us with such force that two of our 3 4 Field Columbian Museum — Botany, Vol. 2. men barely escaped being washed overboard while setting the storm-staysail. We sighted the welcome light on St. George's at daybreak on the 28th and reached Hamilton harbor at noon. Taking one of the yacht's boats I visited a number of the islets in the bay (collecti?ig nos. 1-35), and on the 29th and 30th continued work on the hills and in the boggy swales back of Paget's Landing (36-69). During the morning hours of the 31st an excursion was made to the famous Walsingham district (70-113), and the afternoon until dusk was utilized in a search of the fields and woodlands north of Hamilton (116-139). We left the harbor at 1 o'clock on New Year's day and as we reached the offing, set all sail and laid a course for San Juan, Porto Rico, a distance of 840 miles, making that harbor on the morn- ing of January 5th. January 6th was spent in botanizing over the lowland border- ing the bay at Catano, opposite San Juan (140-193). January 7th a carriage was engaged and a trip taken along the military road from Rio Pedras to Caguas, whence I returned to San Juan on the evening of the 8th (194-248). The afternoon of the 9th was spent in the Catano region with Mr. E. E. Heller, who had just arrived in Porto Rico to collect for the New York Botanical Garden (249- 239). On the 10th, again in company with Mr. Heller, the sand- dune coast region at Santurce was visited (260-303), and on the nth we worked the foothills near Bayamon (306-326, 338-338) collecting at Catano (327-337) while awaiting the departure of the train for that field. The shores of the bay of San Juan are quite distinct in their flora from the seashore, the sandy beach failing to yield those characteristic Antillean forms so predominant everywhere on the true sea coast: Cakile maritima, Ernodea littoralis, Suriana mari- tima, Tournefortia gnaphalodes, Sesuvium portulacastrum, and Euphorbia buxifolia, all of which are plentiful just outside the entrance. The flora of the bay shores consists principally of Wedelia trilobata, Bidens leucantha, Coccoloba uvifera, and Ipomoea pes- caprae. During our stay in this region heavy showers fell upon an average of every three hours; but as they lasted only a few moments, and the herbage dried almost as soon as the rain ceased, they inter- fered little with collecting. We left the harbor on the 16th, and steaming eastward against a heavy wind, spent the night making seventy odd miles to the bay March, 1900. Plantve Utowan/E — Millspaugh. 5 of St. Thomas, which we entered early on the morning of the 17th. Here the day was utilized in collecting about the bay shore and on the hillsides south of Charlotte Amalia {364-502). At four o'clock on the morning of the 18th — having been so fortunate as to secure the same man who acted as a guide for Baron Eggers in his St. Thomas trips — I started across the island by way of the high mountain back of the town. My guide being familiar with the ferny nooks and deep woods where Baron Eggers found many of his more interest- ing species, the trip proved a very profitable one {503-565) and greatly enhanced the value of so short a stay at this island. We sailed at noon of the same day for the island of Culebras, a part of our new Porto Rican territory, and aided now by the trade winds, we made the twenty-five miles handsomely before too dark to effect an entrance to the excellent harbor on its southern coast. January 19th was spent in work on the northern shores of the bay {566-635), and the morning of the 20th on the seashore south- west of the bay {636-640). The shores of the island are clothed with a dense growth of cacti, agaves and low-spreading rubiaceous and leguminous shrubs covered with bromeliads; the cleared fields in from the coast are, however, fertile and productive, and in the pastures the backs only of the cattle can be seen as they graze upon the tall, fresh guinea grass. At 3 p. M. we weighed anchor, left the harbor, and passing to the eastward rounded Viejas Island and spent the night at sea, reaching Playa, the port of Ponce, at seven the following morning. Taking the sailing launch we visited Ratones Island {650-661), which is being so rapidly washed away by the force of the sea that living clumps of Suriana are still standing in the water nearly a quarter of a mile from the receding shore. I walked back along the shore, collecting the coastal forms {662-684); and in the morning we left the port for Guanica, which was reached at noon. Guanica hill proved a very interesting collecting ground {685-710), and the plain and parched tangle of chapparal on the bay shore well repaid the exertion of an entire hot day on the 22d {711-754 and 755-768). Leaving here at ten o'clock in the evening, we arrived off Mona Island at the same hour on the 23d, and drew into an anchorage at El Sardinero, where we attempted to make a land- ing in the dinghy, but without success, the waves being too high to allow us to approach the shore in safety. Reluctantly this coast was abandoned and we moved around the spit into Santa Isabella bay. Here another attempt was made which was again unsuc- cessful, and we were compelled to bear away for our next port — 6 Field Columbian Museum — Botany, Vol. 2. San Domingo — which we reached on the morning of the 24th. I took a carriage and spent the day driving about the environs of the city (769-883). In the early evening we sailed for Port Antonio, on the northeast coast of Jamaica, which we reached on the morn- ing of the 26th. From here a trip was made to Kingston by rail, which afforded me a valued opportunity to visit the Hope Botanical Gardens, and meet the genial Mr. William Fawcett, Director of the Public Gardens and Plantations, but left no time for collecting as we returned to Port Antonio at noon the following day. The 29th was occupied in field work about Port Antonio (884-1000), and in the evening we sailed for Santiago de Cuba, reaching there at noon on the 30th. The afternoon was devoted to mails from home, and the 31st to a trip down the coast in the yacht to visit the wrecks of the Viscaya and Almirante Oquendo. February 1st was occupied in a study of the arid shores of the bay, which at this season present very few flowering plants (1001— 1024); and the 2d in a trip to El Caney {1023-1041) and San Juan Hill (1042-1036). So little rain falls in this region at this season, that the scanty flora sustains insufficient characters to warrant extended collecting. On the 3d and 4th we visited Morro Castle (1037-1103) and "The Ovens" (1104-1126), the l-atter a gulch to the north, in whose rocky sides are many rounded cavities, large and small, which give rise to the name. At this point in the cruise Mr. Mott was called home by busi- ness necessities, and as better accommodations could be secured on a vessel leaving Port Antonio, our yacht was headed again for that place. This gave me a further opportunity to collect there, and the .morning of the 8th was spent in a glen near the village (1127-1149). At 5 p. m. we followed Mr. Mott's steamer out of the bay and laid a course for Cuba at the point where the Cristobal Colon was driven ashore. We sighted her at about ten the following morning, and while the Utowana lay off and on, we boarded the wreck and spent some time upon her side. At Cayman Brae our next stopping place, we found an anchor- age on the north coast close to the rocky shore, near a little settle- ment known as "The Creek." Here, in company with one of the natives, I spent the afternoon along the beach and on the plateau above (1130-1192). A calm delightful evening followed and we retired early with a quiet sea, only to be rudely awakened at eleven o'clock by a horrible thumping. Rushing on deck we found the yacht in a screaming "norther," which, coming up without warning, was dash- March, igoo. Plants Utowan^ — Millspaugh. 7 ing the sea against the iron-bound coast with terrible fury directly under our stern. As soon as sufficient steam could be raised an attempt was made to leave the dangerous anchorage, but before the screw could gain a purchase upon the foam-lashed water our ship struck the rocks, once, twice, thrice, and in the awful suspense of the next moment, when we expected that each second would be our last, the leadsman's welcome cry of "moving ahead, sir," greeted us, sweet as a voice from home. In a few minutes more we were out of danger and the yacht was beating to sea like a frightened thing. Gaining the offing, we squared around the east end of the island and came to anchor again under its lee, where we found pro- tection from the storm. We shifted to a point farther west the next morning and resumed collecting (1193-1219). April and May being the principal floral months here, little was to be expected of plants in form for collection in February, and a tramp of several miles the fol- lowing day resulted in only eighteen species worthy of preservation (I220-I2J7). Leaving Cayman Brae on the nth, we ran across to Little Cay- man, skirting its entire south shore in search of a safe landing-place, but finding none we finally stood off and ran to the southwest, reaching the harbor at Georgetown, Grand Cayman, after dark. Daylight brought the health officer, who with many expressions of regret forbade us to land, as our last port was reported to be infected with measles. However on being informed of the nature of our visit, he consulted with the authorities ashore and the Governor himself came out to us and courteously gave me permission to land at least a mile above the village, but cautioned me to keep away from any person or dwelling that I might encounter. Avail- ing myself of the privilege I made an extended trip along the shore north of the port and into the borders of the lagoon (1238-1263). We made an attempt in the afternoon with our sailing launch to round Jackson Point south of the town in order to further search the shores, but the wind gave place to heavy rain squalls and we were compelled to work back to the yacht. These weather conditions were followed by a dead calm and other indications of a norther. At 5 p. m. a rising wind began to steadily shift to the westward, and at six it became strong and tended northward, where it continued during the night. In the early morning rain again fell in torrents, the wind instantly shifted dead north and blew a gale, and again we were caught on a lee shore. All hands were promptly on deck, and with steam and sail we crept away from danger. As the other shipping in the open roadstead made frantic attempts to secure safety 8 Field Columbian Museum — Botany, Vol. 2. in flight, one pretty white schooner that lay near us was quickly blown high up on the rocks a wreck, and a large trading vessel from Belize, dragging her anchor, threatened to follow, but finally escaped with us around the point into the quiet water of Spot Bay. We were thus driven by the storm to the very point we had failed to reach the day before, a place which, on going ashore, proved of particular interest in its flora. Eighty-eight numbers (7266-1334) were secured here. As I regained the yacht, which was rolling heavily in the sea that now ran in from the point, I arranged the plants in driers on my stateroom floor, a gymnastic feat in the performance of which I had become quite proficient. Tuesday, February 14 — albeit a drizzling rain fell constantly dur- ing the morning — Mr. Armour, Mr. Isham and myself made an extended excursion into the interior of the island (1335-1391), where we encountered the great pest of the place, mosquitoes. While I am unacquainted with the entomological characteristics of this particular species, the horrible torture to which we ungraciously submitted on this trip I had never before experienced. Swarms of the large black creatures settled upon us drawing blood instantly; they refused to be brushed away, only yielding to death. As we neared the center of the island they actually drove us back, and with swollen faces, hands and necks, we fled to the open, conquered and in tor- ment. I was told by a merchant of Georgetown that in May and June these insects became so numerous and terrible that he always closed up his business and left the island. He further vouched for the fact that they killed many head of cattle during the summer and rendered the place uninhabitable except to those people hardened to their poison. In the early evening the weather signs warned us that the south coast was in its turn becoming dangerous, and learning that the norther had abated we ran around to our old anchorage off George- town. Here we learned that the Board of Health had decided to raise our quarantine and we were invited ashore. We found the main street along the water front a wreck from the storm and littered with debris from shore and sea. We were told that the norther had proved the worst the inhabitants had experienced for twenty years. After an hour spent in collecting about the streets and vacant lots, both of which are noticeably free from the usual weeds of civilization (1392-1406), I was summoned aboard by the yacht's whistle, for the wind had again shifted and the anchorage was becoming untenable. All sail was quickly set and we left this storm-beaten group on a course for the Isle of Pines. March, 1900. Plants Utowan.*: — Millspaugh. 9 We landed at Pedernales Point at 3 p. m. of the 16th, and worked over the coastal field {1407-1445) until evening, when we left for the extreme western point of Cuba — Cape Corientes. Reach- ing the anchorage off the cape at 8 a. m. we went ashore and began our search of the coast for a mile or so each side of our landing- place. The coast here is of sharp, flinty coral, dry and forbid- ding, and the vegetation parched and almost characterless at this sea- son. Exhaustive search until evening only resulted in twenty-two num- bers [1446-1467). Leaving on a course S. W. % W., we made a delightful sail of 150 miles to the Island of Cozumel, 10 miles from the east coast of Yucatan, and dropped anchor off the village of San Miguel at noon , of Saturday, February 18th. We found the conditions about as they were four years before when with the yacht " Ituna" we visited the island. In the afternoon I made an exhaustive search of the open woodland along the coast north of the village (1468-1508). The 19th was spent in field work at the Caleta, a bight in the coral coast about three miles south of San Miguel, where the woodlands are moist (1500-1537). In the evening our vessel rested as if in dry dock on the still, transparent waters of the only quiet anchorage on the whole Yuca- tan coast, and we enjoyed a calm delightful night of refreshing sleep. Early the next morning I started for an extended trip to the interior of the island accompanied by a Maya guide, an intelli- gent fellow who proved of great assistance in recalling to my memory the Indian names of such plants as I had collected here before, and in naming new ones as they were gathered (1538-1575). Our anchorage was shifted in the evening to the shallow waters off the north shore in preparation for the next day's work. Soon after sunrise of the 21st the entire party, well equipped with food and water, disembarked from the steam launch at the northeast point of the island for one of the most severe tramps of the cruise, a journey over ragged coral and deep sand, and through tangles of Sabal, Coccoloba, Suriana and Ernodea, to a ruined Maya temple eight miles down the east coast, which we under- stood had never before been visited. This coast is of great interest to the botanist, as the Gulf Stream sweeps its sands leaving masses of driftwood even to great tree trunks scattered along its beach, and would doubtless offer many interesting ecological lessons to one who could spend a month here during May, June or July {1576-16 1 2). In order that a full day's work might be done at Mugeres Island, 10 miles north from our anchorage, our captain was instructed io Field Columbian Museum — Botany, Vol. 2. to get under way at 4 a. m., at which hour we were suddenly awakened by a violent shock. In attempting to leave the shallows we had struck a coral head and were now thumping and grinding into its yielding crown with every wave of the sea. For four long hours every means was tried without avail to extricate the ship from its position, until just as we had about decided that the beau- tiful fabric was destined to remain aground until totally wrecked by a "norther," a roller considerably higher than any of its predeces- sors came over the sea and upon its crest we quietly slid into deep water. These repeated dangers convinced us that our vessel was too large to safely lie about such shores; we therefore abandoned our intention of stopping at harborless Mugeres and passed on to the eastward. Progreso, the seaport of Yucatan, was reached about noon on the 23d, whence we proceeded by train to Merida 25 miles inland, where we were entertained at the pretty Quinta of the American Consul, Mr. Edward H. Thompson. The objective point in Yuca- tan to be visited by the party was the ruins of the ancient Maya city, Chichen Itza, about sixty miles farther inland by rail and native wagon. In order that I might visit Dr. Geo. F. Gaumer who for the past four years had been collecting botanical material for this Museum, I started from Merida a day in advance of the party. From Izamal I was obliged to travel seven leagues in a volan that I might reach Tunkas and join the others who were to arrive direct from Merida by rail. The distance was covered in the unusually quick time of three hours, over a road so dry and hot that the cochero was compelled to drench the wheels at each watering-place to keep the tires from dropping off the felloes. The night at Tunkas was spent in the only accommodations of the village — two bare rooms, whose sole furniture consisted of wooden pegs from which we hung the hammocks providently carried with us. Our breakfast the next morning consisted solely of chocolate and bread, a poor fortification for the five-league ride over the most rocky of roads in that most "rocky" of vehicles — the volan coche. At Chichen Itza we spent four days at the hacienda of Mr. Thompson, visiting the ruins and incidentally collecting such plants as I had not secured there on my previous trips (1616-1648), and on Friday, March 3d, we returned to Tunkas. The night train from here proceeded only two leagues to Temax, a village so des- titute of accommodations for travelers that we sought the privilege of hanging our hammocks in the railroad freight house. Here we March, 1900. Plants Utowan^e — Millspaugh. ii were lulled to sleep by the pattering fall of countless disappointed fleas which, in their vain attempts to reach us, dropped back upon the papers we had spread beneath our hammocks as a rug. At half after four in the morning we again boarded the train and reached Merida at half past nine. Later we enjoyed a swim in Mr. Thompson's irrigating tank and regained the yacht in the early even- ing. Divesting ourselves of our clothing on deck, that we might not contaminate our cabins with the various predacious insects with which we were covered, we soon luxuriated in cleanliness and creat- ure comforts. Rowing ashore at 4 a. m., March 5th, I spent the day tramping over two leagues of the lagoon border and arid scrub land south of Progreso {1643-1737^. A condition peculiar in Yucatan existed at the time of this trip. Instead of the usual northeast trades the wind had been prevalent in the southeast, bringing more rain than had been known in the peninsula for twenty years. This rendered the herbage and shrub- bery of the wooded lands greener, and blooming plants more plenti- ful than I had seen in my previous visits, and served to render my col- lections at Chichen Itza and on the arid plains near Progreso espe- cially valuable. The "northers" did not begin on the Yucatan coast this year until our first experience with them at Cayman Brae on the 8th of February. The second one, which drove us out of the offing at Georgetown, Grand Cayman, on the 13th, dropped the temperature of Yucatan to 41 ° F., the coldest known to the present generation. These moisture and temperature conditions formed an era in the life of the inhabitants that will be a tradition for decades to come. I returned to the dock about 5 p. m. The launch awaited me at a short distance, tossing on an angry sea raised since morning by a steadily increasing northeast wind to such a height that the Captain of the Port expostulated with us for attempting to make the four miles to the anchorage of the yacht. However with Mr. Armour at the helm, we started off into the wild wind and waves against which we fought our way to the vessel. As we drew near, the entire crew gathered at the rail and watched our coming with anxious faces. We finally gained the deck by leaping from the crest of a rising wave into the arms of the waiting officers. The captain, fearing a shift of the wind to the north, made immediate preparations to raise the anchor and put to sea, which all steamers in the offing were doing as rapidly as possible. At eight o'clock the wind veered full in the north, the barometer rose, the thermome- ter fell, and another "norther" burst upon us. It blew with fury all 12 Field Columbian Museum — Botany, Vol. 2. that night and all the following day, during which we lay hove to about 25 miles from the coast. Monday night was spent in discomfort until about five in the morning, when the wind died down though the sea remained extremely rough and choppy. At eight o'clock we shaped our course as true as dead reckoning admitted, for the Alacran Shoals and spent the day searching for them. Circling sea-birds finally in- dicated their presence, and an hour later we dropped anchor in com- paratively quiet water under the lee of Perez Island where we spent the night. Mr. Armour accompanied me ashore before sunrise (March 8th), where a thorough canvass was made of every plant species (1738- I7S7)- Later the entire party visited the other islets: Pajaros {1758- 1764), Chica and Allison (1766-1771), collecting and photographing, and shooting snipe for the larder. The sea was too heavy to permit landing at the northernmost islet of the shoal, so we drew away from the dangerous waters as evening fell, and shaped our course almost due north for the jetties of the Mississippi. With a strong wind and all plain sail set we averaged 8*4 knots through the night, increasing to 10 knots during the following morn- ing and 14 in the afternoon, when at five o'clock a sudden and fright- ful shock thrilled the ship. Had we found rocks in water known to be 1,500 fathoms deep ! We rushed to the rail and found the sea brown with blood ; we had struck a sleeping whale full broadside, evidently wounding him severely. He rose astern accompanied by his mate, where both blew and sank. The shock must have weak- ened our fore top-mast, for an hour later it broke short off at the masthead and went by the board. In this crippled condition, but without further accident, we entered the Mississippi at 2:30 on the afternoon of the 10th of March, and steaming up the 100 miles of river during the night, reached the dock at New Orleans at 7 a. m., March nth, our eventful and profitable cruise ended. The foregoing outline is chiefly intended to fix the dates and extent of time devoted to each collecting station, and to give some slight idea of the weather conditions that prevail in the Antilles at this season of the year. A detailed account of the work and obser- vations made of existing conditions at each locality will be issued as a second part of this publication, which will also include the plates and indices.

Plentiful near the cenote Nohoch Chen, Chichen Itza, Yucatan (1620), called by the Ma^yas X-mux-coc, "dried pectoral," although no use is made of the plant in asthma, difficult breathing, or kindred complaints by the Mayas of the present day so far as I am able to determine. It is used as a remedy in catarrhal affections of the chest when expectoration is profuse. A literal translation of the Maya name \stnux — dried or desiccated; coc — asthma, difficult or wheezy breathing, the prefix X simply denoting the feminine gender. Selaginella longis- picata Underw. Field Col. Mus. Bot., 1:287, is also called X-mux-coc; the two species are used indiscriminately in domestic medication. PTERTDOPHYTA.* POLYPODIACEvE. Aspidium scolopendriodes (Linn.) Mett.

I quite agree with Shimek (Ferns Nic. 191) that with a full series of forms no specific differences exist between G. calomelanos and G. tartarea Desv. , and the above localities for Dr. Millspaugh' s specimens seem to bear out Prof. Shimek's remark: "The difference in texture seems to be due to surroundings. Both forms are more coriaceous when growing in barren, exposed places. Chkilanthes microphylla (Swtz.) Syn. Fil. 127. Adiantum Swtz. Prod.

If I am correct in this determination (and the specimens agree with those I have from Mr. Gilbert), the published descriptions need considerable revision: In the only two fronds I have of normal A. bellum, and for which I am indebted to Mr. Gilbert, the pinnules are *Original orthography. Gymnogramme of Kunze Flora. 20 Field Columbian Museum — Botany, Vol. 2. firmly adherent, and are mostly attached to the pedicel by a "short y-shaped furcation," as described by Moore, while in Mr. Gilbert's specimens of the variety, as well as in these of Dr. Millspaugh, there is at least a partial articulation as seen in the falling away of some deciduous pinnules, and the leaving behind of either a blunt apex, or a very short one-sided attempt at furcation. Adiantum cristatum Linn. Sp. PI. 1558. Moist hillsides near Bayamon, Porto Rico (356). Adiantum deltoideum Swtz. Prod. 134. In the crevices of the dry walls of Diego Columbus' Castle, San Domingo (769). In a like situation on the walls of Morro Castle (1096, 1 107, 1 108), Santiago de Cuba; the latter station producing especially large and fine plants. -/ Adiantum obliquum intermedium (Swtz.) Shimek, Ferns Nic. 145. A. inter?nedium Swtz. Prof. Shimek (1. c. pp. 142-145, pi. 6-7) has, it seems to me, by an admirable series of figures, shown quite clearly the difficulty of keeping A. intermedium, A. Kaulfussii Kunze and A. obliquum H. & G. longer apart, and my own series of speci- mens, and the following plants, certainly appear to confirm his judg- ment. Deep rich woods on the mountain back of Charlotte Amalia, St. Thomas (549), and in rich shady woodlands near Port Antonio, Ja- maica (1 146). Adiantum pulverulentum Linn. Sp. PI. 1559. ~j Rocky well-shaded ravine (907), moist deep glen (1 134, 1147) and under a moist overhanging bank (1788) near Port Antonio, Jamaica. This whole series shows much variation, while 1788 has some sterile fronds greatly resembling A. obliquum intermedium. Adiantum tenerum Swtz. Prod. 135. On dry rocks east of the river near San Domingo City (811), and in rich soil of a shaded glen near Port Antonio, Jamaica (905). The specimens plainly show that the latter situation is the health- ier for this species, for while the plant is fresh and clean, retaining its leaflet, the former is dry and has hardly a leaflet remaining on its depauperate stems. Pteris aquilina Linn. Sp. PI. 1533. On a hummock in a bog near Paget's, Bermuda (57). The segments of this form are narrow, and the plant approaches variety caudata, but is only slightly pubescent. Pteris aquilina caudata (L.) Hooker, Spec. 2:1858. P. caudata Linn. In open moist woods in the center of the island, Cozumel (1551, 1565), where it is called X-ual-kanil, "yellow fly-brush," probably from its use for the purpose of keeping off flies. Pteris longifolia Linn. Sp. PI. 1531 . Rich, moist soil on hillsides near Bayamon, Porto Rico (310). March, igoo. Plantve Utowax.-e — Millspaugh. 21 Frequent on dry rocks near San Domingo city (812, 816). In rich soil of a rocky glen near Port Antonio, Jamaica (897, 935, 1789, 1790). The above specimens are mostly rigid, pubescent forms, of which 816 is very large ; but 812 is quite flaccid, tender and sterile. No. 1789 is a small plant having two of its sterile fronds with apical pinnae suppressed, the upper lateral pinnae on one of them much elongated, and one small frond with the upper pair of pinnae much elongated and the terminal one dwarfed into a small, roundish cordate apex. No. 1790 is an unusually interesting plant, showing one frond with a stipe a foot long bearing above several pairs of deeply pinnatifid pinnae: The whole frond young and tender and resembling in form, texture and pubescence a young Aspidium patens. This frond, if detached from the parent plant, would never be considered to belong to the species by any one. It is a remarkable variation similar to one described* as having been found in Polypodium pellucidum. Polypodium achillejEFOlium Kaulf. En. Fil. 116. Rich, open field near Port Antonio, Jamaica (911). The specimens do not fully answer to the description in Synopsis Filicum (H. & B. 388), but agree so well with the illustration of this species in Kunze's supplement to Schkuhr's Farnnkraiiter, t. 43, f. 2, that I am inclined to place them here. Polypodium aureum Linn. Syst. Nat. 2:692. Deep mountain woods above Charlotte Amalia, St. Thomas (557). Texture thin, areoles with flattened, free veinlets. Polypodium lycopodioides Linn. Syst. Nat. 2:691. Climbing Sabal trees near the Caleta, Cozumel (1534). Polypodium pectinatum Linn. Syst. Nat, 2:691. Rare, in crotches of- low trees near Port Antonio, Jamaica (896). Polypodium Phyllitidis Linn. loc. cit. In the crotch of a low tree on the high mountain back of Char- lotte Amalia, St. Thomas (546). On an old stump near San Domingo City (813). On trees near Port Antonio, Jamaica (999). The only really distinctive character that I have been able to find between this species and P. repens is in the rootstalk, and where this is wanting it is not always certain in placing the specimens, as the venation varies in different, and sometimes in the same plants. Fournier, Mex. PI. Crypt. 85 makes P. repens Mett. a variety of this species, and Shimek considered it a synonym. I have placed the above specimens here on account of their very stout, almost globular rootstalk ; the venation in some instances cor- responds to that of repens, and in others to typical Phyllitidis. The rootstalk in repens should be long and slender. Polypodium piloselloihes Linn, loc cit. Climbing the trunks and running the branches of trees, near Port Antonio, Jamaica (1143). *The author's paper read before the Joslyn Bot. Club, Waterville, Maine, in August, 1898. 22 Field Columbian Museum — Botany, Vol. 2. POLYPODIUM REPTANS SwtZ. Fl. Ind. OcC. 1655.

Moist, rich banks, foothills at Bayamon, Porto Rico (347, 351, 353). Moist, rich woods on the mountain heights above Charlotte Amalia, St. Thomas (547, 553)- Rich woods near Port Antonio, Jamaica (1148), sterile, with large pinnae. Mr. Baker, in his recent Synopsis of Brazilian Ferns, has adopted Poiret's older name Androgynum for this species, but, as I have not been able to investigate this to my own satisfaction, I have retained here the Swartzian name which has been in use for nearly a century. Mettenius referred this, as well as P. reptans, to Phe- gopteris, in which he has been followed by Prof. D. C. Eaton and others, but I can only look upon both these as true Polypodia^ of the Goniopteris section. Polypodium thysanolepis A. Br. ex Klat. in Linn. 20:392. Quite large specimens, on trees near Port Antonio, Jamaica (890, 1787). Polypodium vacciniifolium Fisch. & Lang. Fil. 8, t. 7. Climbing small saplings on a hillside near Bayamon, Porto Rico (307)- Imperfect specimens only, and somewhat doubtfully belonging here, but not safe to place elsewhere. My specimens resemble a smooth form of piloselloides. Acrostichum aureum Linn. Sp. PI. 1525. In a bog near Paget's, Bermuda (52). In a brackish marsh east of Port Antonio, Jamaica (953). Springy bog in the center of the island Grand Cayman (1377). Also seen in the open mangrove swamp between Cataiio and Bayamon, Porto Rico, but could not be reached. No. 52 presents the upper portion of fertile frond with 14 pairs of erecto-patent obtuse pinnae and bifid apex ; no. 1377 consists of 3 large sterile pinnae on rachis a good inch in circumference, and a portion of a fertile frond with 6 pairs of pinnae, mostly with acute or cuspidate apices, but some obtuse, a good example of the non essen- tial character of the apical termination. No. 953 gives portions of fertile and sterile fronds, bright green in color ; pinnae on the sterile frond long and narrow, suberect, obtuse, with cuneate stalked bases; those of the fertile frond sterile below and twice the length of the upper fertile ones. SCHIZiEACEiE. Anemia adiantifolia (L.) Swtz. Syn. 157. Dty banks near Bayamon, Porto Rico (315, 358), and same situ- ation near Port Antonio, Jamaica (910, 917).

Zamia Allison-Armourii sp. nov. Rootstalk semifusiform, amylacious, 20 cm. long, 3-5 cm. in diameter; leaves, 5, palmose, 75 cm. long; petioles glabrous through- out, trisulcate from the base; leaflets all alternate, 16 jugal, broadly linear-lanceolate, narrowed at the base, round-pointed and slightly sharp-serrate at the apex, not falcate, prominently and distinctly 26- veined, the median 18-20 cm. long, i. 3-1.5 cm. broad, the basal and apical leaflets 16 cm. long, 1.3 cm. broad, somewhat more promi- nently serrate, the margins not revolute. Male strobiles in anthesis 9 cm. long, 1.5 cm. diameter, cylindrical acute at the base and apex; peduncle 5 cm. densely rusty tomentose; peltae transversely ovate, rusty tomentose, 5x4 mm. arranged in 9 longitudinal rows. Type in Field Col. Mus. Herb. No. 60817. Near Z. augustifolia and Z. Portoricensis Urb. Syll. Antill. 291, but differing entirely in general and special habit. The nearest speci- men of Z. augustifolia is Wright's Cuban 1463, the leaflets of which are sub-falcate 13 x 1.8 cm., more or less 30-veined, the veins indis- tinct, leaf sharply serrate from near the middle.

Notwithstanding the excellently dif- ferentiative treatment of this species by Dr. Maxwell T. Masters in Jour. Bot. 1899:1, I cannot specifically separate it from J. Virginiana Linn., though, in the absence of fuller specimens, I deem it best to retain the more local name. The differences shown by my fruiting specimens from many American coast specimens of Virginiana might well be due to environmental causes. TYPHACE.E. Tvpha Domingensis (Pers.) Kunth, Enum. 3.

In determining the limits of this genus I prefer to accept the interpretation of Grisebach, Bentham, Otto Kuntze and others who made it to include Mogiphanes Mart, and Telanthera R. Br. excl. Litho- phila Sw., that is, all species of the Capitato-spicate Gomphronece with undivided stigma, and stamens which alternate with sterile filaments upon a more or less cup-shaped tube.

The wide range of this species includes southern Florida, the West Indies, coastal Mexico, Central and South America. Care should be observed to distinguish it from A. Costaricensis Kuntze, which is described as being more or less fasciculately pilose, the anthers glo- bose instead of oblong, and having staminodia laterally instead of apically pectinate. Alternanthera Culebrasensis Uline, Field Col. Mus. Bot. 1: 420.

Nearer A. {Telanthera) Sintenisii Urban /. c. than the preceding, but the pubescence on the leaf of the latter is described as "supra laxius subtus densius pilosis," upon which rests the chief difference in the above species. It may prove to be only a variety — a question which only a comparison of the two plants can decide. 38 Field Columbian Museum — Botany, Vol. 2. [Alternanthera spinosa Roem. & Schult. Specimen 268 of Combs, Santa Clara district of Cienfuegos. Although no details of pubescence characters are given in the descriptions of this species, it is safe to conclude that the verticillate branching of the hairs clothing the stem and under surfaces of the leaves has been overlooked. The heads are more strikingly spinifer- ous than the other West Indian species of Alternauthera.] Alternanthera paronychioides St. Hil. Voy. Brds ii, 2: 43. Dry roadsides near Guanica, Porto Rico (725, 748). Not readily differentiated by its dense prostrate habit alone from A. repens, but widely removed in its flower characters. Stamens much longer than the short, wide, more or less dentate staminodia. LITHOPHILA Sw. Prod. Viq. Ind. Occ. 14(1788). Lithophila muscoides Sw. Philoxerus R. Br. Prod. 416 (1810). The genus Lithophila seems so clearly defined in habit and floral structure as to deserve recognition apart both from Iresine and Alter- nanthera. Iresine it is true may sometimes have a capitate inflores- cence, but its flowers are never compressed as in Philoxerus; in cases of capitate inflorescence in Iresine the heads are never enveloped or subtended by leafy bracts as in Philoxerus and Lithophila; while the staminal cup of Iresine has always either the rudiment of a stamino- dium or a rounded or pointed elevation of the margin of the cup where the staminodium would otherwise arise. In Philoxerus as well as in Lithophila, which differs from Philoxerus essentially in having 2 to 3 stamens, the sinuses of the cup between filaments and filament- rudiments are so shaped as to preclude the theory of staminodia at any period of the history of their development. Bentham & Hooker's Genera Plantarum describes the cup of Lithophila as simple or den- tate between the filaments. Such dentations will probably be found to be rudiments of the deficient 4th and 5th stamens corresponding to the full number 5. For the proper interpretation of staminodia, it must be remembered that the rudimentary filaments arising on the cupule in the position of the deficient stamens in Lithophila are essentially different in their significance from the teeth or staminodia of Iresine and Alternanthera, which are alternate with the filaments and with the calyx segments, never opposite as in Lithophila. Dr. Kuntze in a discussion of the relationships of the group in his Revisio Plantarum ascribes staminodia also to Philoxerus; in a large number of specimens of Lithophila vermiculata (L) Uline examined, I have not found the slightest indications of them. Grisebach, Flora West Indies, also recognizes this entire absence of alternating staminodia both in Philoxerus and Lithophila as an essential generic character, but he goes a little further and keeps the two apart on the basis of the dif- fering number of stamens. This variability in number of stamens occurs elsewhere in the Amaranthacea>, and certainly can not be justifi- able as a genuine character. From a phylogenetic point of view the creeping or prostrate species of the group seem to be plainly depauperate forms adapting themselves to conditions offering meager nourishment, e. g., sea-shore, sandy or rocky places, etc. The result March, igoo. Plants Utowan.i: — Millspaugh. 39 is seen in (1) the great reduction in size of the plant and all its parts accompanied by the dense prostrate habit, (2) the disappear- ance of two or three stamens indicated by the sterile filaments which are found standing in the position of the fertile stamens with reference to the perianth segments. In the light of the above considerations the following revision of Kuntze's arrangement of the Gomphrenese is suggested, to the extent that it is affected by the changes here presented: A. Genera characterized by solitary or fasciculate flowers, Guillemenia, Cledothrix. B. Flowers capitate or spicate. a. Perianth segments+coalescent, Froelichia. b. Perianth segments free. a.

Cakile maritima Scop. Fl. Cam. ed. 2, 2:35. Even with the careful and discriminating characters in Prof. Robinson's Cakile in Syn. Flora. N. A. 2, 1:132, I cannot separate the specimens gathered into species according to the leaf or fruit forms credited to each, as they constantly intermix, the leaves of Americana and fruits of maritima appearing on one plant, while the reverse may and does occur, I therefore am compelled to place all individuals gathered, under the older species. The plant seems to require the clear clean sea air and spray, as it is not to be found on the shores of large bays, though across the spits dividing such bays from the sea it is found in profusion. Seashore sands at Santurce (272), Culebras Island (626), Ratones Island, and Port of Ponce (676), Porto Rico. Coral-rock shore line at The Creek, Cayman Brae (1159), where it is known as "Bay-bush." Leaves entire, lanceolate, rachis somewhat geniculate, fruits cylindrical-fusiform, upper cell the longer, pointed, barely angular; plants depauperate from the character of the location. Another specimen (1179) from the sandy beach beyond the rocks, has the leaves all entire, but varying from narrowly lanceolate to ovate, fruits not developed. Still another (1179^) plant from the identical locality, in fact one of a clump of which the previous specimen formed a part, has ovate-spatulate leaves, the lower simply sinuate toothed, the upper deeply and irregularly sinuate-cleft, fruits undeveloped. Specimens from the sandy shores of Spot Bay, Grand Cayman (1308), have narrowly lanceolate, sinuate-dentate leaves, the fruits have the upper cell elongated acute and 5-7 ribbed. The sandy beach at Cape Corientes yields a form (1465) with sinuately divided leaves throughout, the fruits comparing perfectly with those of the last mentioned 1308. The western shore of Perez Island yields a form (1744) with lanceo- late and ovate-spatulate entire leaves, and fruits with a large tumid upper cell, sharply apiculate, and furrowed rather than angled. Pajaros Island, adjacent, yields a form (1764, 1767) with thick leaves of the form of the last, and fruits the apical cell of which is almost globose-apiculate, while the lower cell is little other than an obconi- cal peduncle. While the plants from both Perez and Pajaros Islands are large fruit producers they have a sickly yellow appear- ance compared with the fresh, cool green of those of Chico and 44 Field Columbian Museum — Botany, Vol. 2. Allison Islands of the shoal. These plants have leaves varying from exact counterparts of the last to sinuate-dentate, and sinuate-cleft forms, while the fruits of both the last forms appear indifferently upon these. [Specimens of this species gathered on the shores of Lake Michi- gan, near Chicago, are fully as variable as these from the West Indies; clumps in various localities yielding forms that might be placed under either this or Americana as described, and others that intermix both.

Tribulus Alacranensis sp. nov. Plate xlviii & Ixi. Perennial runner. Rootstock long and ligneous, stems many, ligneous, thick (4-7 mm.) 20-24 striate, .5-2.5 meters long; branches nude, ligneous, .5 to 1 meter long, many jointed, joints all about 1.5 cm. long, nodes rough with the withered persistent bracts and stipules of deciduous leaf stems, branchlets infrequent along the branches, mainly aggregated at the tips, very woolly with silvery down, interpet- iolar bracts triangular, stipules linear, pointed (1 cm.), usually of the length of the leaf stem from the axil to the first jugae. Leaf sensitive, closing slowly but too quickly to be flat in the collecting papers, 3-5 cm. long, stem densely silvery-tomentose, leaflets 8-jugal densely tomentose above and below, flowers all terminal, the peduncles during anthesis the length of the leaves, but in mature fruit only one half the length. Flowers bright chrome (Prang YYO) closing early in the sun, about half the size of those of T. cistoides, anthers twice the size. Pistil clothed with long, straight hyaline setae which persist even on the fully ripe fruit. Ripe fruit about one-half the size of that of T. cistoides, carpids truncate, somewhat tuberculate, median ridge prominent, 4-6 spined, the main pair divergent, the apical pair very short, the median pair situated near the commissure on the median line of the margins, one or both spines of the median pair fre- quently wanting. This species has probably developed its special characters through its environment from a parentage in T. cistoides, to which one of its leafy branches, if taken alone, will bear a close gross resemblance; the whole plant, however, in its long, tangled^ jointed, woody branches and mass growth, is clearly distinct.

Plantve Utowan^e — Millspaugh. 55 A large mass of this species occupies the south center of Allison Island where its ligneous stems and branches constitute the sole mate- rial with which the colony of frigate-birds here construct their large nests (1766). Quite a large area of the species occupies a partly bare spot on the west center of Pajaros Island, which, though much fre- quented by the frigate-bird, is not used as a nesting ground (1758). A small number of scattered individuals are to be found on Perez Island, which appears to be shunned by all the sea birds of the other islands (1752).

Flat sandy fields near the coast at Cape Corientes, Cuba (1462). Euphorbia buxifolia Lam., Diet, ii; 421. A very large number of examples of this species were collected and a still greater number examined in the field, from which the fol- lowing characters are drawn: E. glabrata Sw. Prodr. 76, E. littoralis Kth., H. B. K., Nov. Gen. et Sp. ii. 44; E. salina Willd. in Hb., E. mesembrianthemifolia Jacq. Stirp. Am. 151. Suffruticose, glabrous; leaves sarcous, ovate, pointed, entire; lower stipules deltoid, median triangular, those of the apical leaves generally geminate, all more or less fringed or long setose-fimbriate. Involucres few at the apices of the branchlets, turbinate, smooth without and within, glands 4 concave, appendages white, longer than broad, margin entire or tending toward crenation, lobes triangular-truncate, mostly bifid at the apex, the two flanking the sulcus broader and 3-8 fimbriate, fifth gland replaced by a deep sulcus from which rises a long narrow digit-like process of the invol- ucre (false lobe).

Forma reclinata: Similar to the species but nearly prostrate in habit, with larger and broader leaves, broader blepharose stipules and shorter and denser branchlets. Perez, Pajaros and Allison Islands, Alacran Shoals (1739, 1763, 1769). Forma seminuda: Similar to the species but with long, nearly nude, zig-zag stem and branches, internodes 1 to 2 cm. long, branch- lets leafy, stipules as in the previous form but narrower. Perez Island, Alacran Shoals (1738% 1742). Forma florida: Similar to the last but with very small leaves on the branchlets which are so densely crowded with flowers and fruits as to appear like capitate clusters protruding from the bare branches. East shores of Cozumel Island (1589); Perez, Chico and Pajaros Islands, Alacran Shoals (1738, 1739, 1747, 1751, 1762). Euphorbia buxifolia flexuosa (Kth.) Boiss., in de C. Prod, xv: 15. Plant pale green, stems flexuous, with comparatively long inter- nodes. Stipules deltoid broad at the base, shallow-fringed at the apex; leaves oval-oblong or ovate, cordate-auriculate at the base, the majority of them showing a tendency to, or actually slight denticu- late at the apex, barely mucronulate.

Euphorbia buxifolia ramosissima var. nov. Erect, profusely short branched from the base appearing like a ball when growing. Leaves exceeding numerous, small, 7 x 3.5 mm. obliquely auriculate-cordate at base, absolutely entire at the simply acute apex. Involucres usually sparse, pedicels as long or longer than the involucre which is of the size of the species, glands smaller, appendages larger, hairiness of internal surface of involucre pro- nounced but not so marked as in var. flexuosa Boiss. Seeds 1 x .7 mm. smaller than the species or var. flexuosa, dorsal angle forming a prominent keel, reticulations barely visible. The Creek, Cayman Brae (1180), Georgetown, Grand Cayman (1262). Not plentiful at either place. All the forms of E. buxifolia prefer a locality where the wind sweeps free from the open sea. They are rarely found at all on the sandy shores of bays or straits. Careful search of the shores of San- tiago and San Juan bays failed to yield a single specimen. Euphorbia pilulifera L., Am. Ac. 3:114. The usual erect form with broad and large leaves was taken at Catano, Porto Rico (329), and Charlotte Amalia, St. Thomas (489, \/ 490); and the narrower leaved form having a tendency to being simple stemmed, at Catano, Porto Rico (1775); Charlotte Amalia, St. Thomas (426, 396), and San Domingo (846). Euphorbia pilulifera discolor Engelm., Bot. Mex. Bound. 188.

Specimens with very long leaves 5-6 x. 6 cm. from the sandy sea beach west of Port of Ponc£, Porto Rico (675). In this species the lobes of the involucre are almost without special form, being involved in the structure of the hairy ring that surrounds the internal involucral-margin; in our specimens the glands have no vestige of appendages, the fifth gland is replaced by a very slight sulcus flanked by two larger involucral lobes (?). The seeds are ovate 2. 1 x 1.3 mm., apiculate, the dorsal angle obsolete, all facets, scrobiculate. Euphorbia Armourii Millsp. Field Col. Mus. Bot. 1:28, pi. 2.

Cent. Euph. 6. Dry, barren opens south of the lagoon at Progreso, Yucatan (1696). In this species the involucre (according to the type speci- men collected "Mexico and Huajaca, Karwinsky,") is hairy exterior- ly, the involucral lobes are triangular-lanceolate, the glands minute, the fifth being replaced by an obtriangular sulcus flanked by slightly enlarged lobes, the appendages are minute crenated or wanting, and the seeds pink or salmon-color, ovate-tetrangular .9 x .6 mm., the ventral facets slightly 4-rugose transversely, the dorsal still more slightly rugose, and the angle prominent. Euphorbia stipitata sp. nov. Plate lxvi. Annual, prostrate, stems and branches glabrous, internodes long, stipules slender cylindro-aristate entire ; petioles short, leaves all ovate-oblong, cordate and strongly oblique at the base; blunt at the apex, pilose beneath, crenate-dentate except at the base. Inflores- cence in terminal many-flowered short peduncled cymose clusters, pedicels about the length of the peduncle and the involucre ; involu- cres hairy, sub-campanulate or cylindro-campanulate, lobes triangu- lar very hairy, glands 4, circular, raised on long stipes, appendages small, rounded, white, attached to the stipe beneath and a little below the gland, fifth gland represented by a broad, deep, round-based sul- cus. Capsules pilose, carpids acute-angled, seeds pink-ashen 1.05 x .65 mm., bluntly quadrangular, the dorsal facets plane, the ventral slightly concave, all facets slightly marked by interlocking (not anas- tomosing) ridges. Stems and branches glabrous except at their very tips 18-30 cm. long, internodes 3.5-4 cm., nodal leaves 10-13 x 5~7 mm., involucres 1 mm. Related to E. maculata L. , from which it differs in its glab- rous stems, immaculate supra-glabrous larger leaves, entire cylindro- aristate stipules, and strong seed characters.

Inflorescence solitary in the axils of the upper leaves, involucre glabrous, short pedicelled tubulo-campanulate, lobes blunt-triangular papillate, the two flanking the sulcus larger; glands 4, small, cupuli- form, appendages rudimentary or most often wanting, fifth gland replaced by a thread-like prolongation of the involucral tissue at the base of the very shallow sulcus; capsule shallowly trisulcate, carpids bluntly keeled; seeds brownish-red, farinose, quadrangular, 11 x.g mm., dorsal facets convex, ventral very slightly concave ; markings discernable, but too slight to take on describable form. Stems and branches 10-20 cm., internodes 8-10 mm., nodal leaves 5-8 x 3.5-4 mm. This species, which in general habit closely resembles E. maculata L. , is probably the plant reported in Ber- mudan collections as that species, but I could not find it on the islands. JE. Bermudiana is common in general, but especially so at Paget's (2, 41), on the islets in Hamilton Bay (7, 9), and about Wal- singham (101). It differs from E. maculata in its lack of hairiness, and in its floral and seed characters. Type in Field Col. Mus. Herb. No. 60101. Euphorbia Blodgettii (Engelm. in Herb.) Hitch. Rep. Mo. Bot.

The following characters, in addition to those given by Hitch- cock, are drawn from the type: Involucral lobes triangular-lanceolate, entire though appearing fimbriate on account of their large hairs, the two lobes flanking the sulcus apparently larger; glands 4, small oval, their appendages various in form, the two next the sulcus always largest and usually 3-crenate on the margin, the two smaller append- ages entire, notched, or 2-3-crenate ; the fifth gland represented by an awn-shaped prolongation of the involucral tissue at the base of the obtuse sulcus. Seeds red pink, farinose, quadrangular 1 x.Smm., the dorsal facets convex, the ventral slightly concave; dorsal facets very slightly marked by interlocking transverse ridges. Related to E. stipitata Millsp., from which its characters readily separate it. Sandy paths near Georgetown (1257, 1258), Spot Bay (13-14), and Bodden Bay Road (1333), Grand Cayman. Euphorbia prostrata Ait. Hort. Kew. ed. 1, 2:189. The pilosity of the angles of the otherwise smooth pod is a strik- ing characteristic of this species which in its general habit might otherwise be mistaken for E. maculata L. To the characters as elaborated by Boissier in his Cent. Euph., the following, drawn from the tvpe, might be added: Involucral lobes bluntly triangular, papillate, the two flanking the sulcus generally larger, glands 4, small, plicate, appendages rudimentary or wanting, March, igoo. . Pi w i Utowan/e — Millspaugh. 67 fifth gland replaced by a shallow unoccupied sulcus. Seeds pink- ashen, sharply triangular . g x .6 mm., the dorsal facets slightly con- vex, the ventral as slightly concave, all marked by 5-6 sharp trans- verse ridges, two or sometimes three of which anastomose, and all include the angles. Infrequent at Walsingham, Bermuda (114), at Catano, Porto Rico (334), and on the south shores of Culebras Island (i77g). Euphorbia pergamena Small Bull. Torr. Club, 25:615. Plentiful at the base of trees, stumps and stones near the sea at Pedernales Point, Isle of Pines (1436, 1442, 1443). The following characters drawn from the type, Collected at Miami, Florida, November, 1878, by Dr. A. P. Garber and distribu- ted as E. albomarginata, should be added to Dr. Small's description: Stipules linear, entire, about twice the length of the petioles; fifth gland represented by a broad and deep triangular sulcus flanked by larger triangular involucral lobes, and the glands next each of these lobes long-appendaged with large oblique (auricular) and some- what irregularlv crenate appendages. Seeds ashen, .85 x.6 mm., strongly tetragono-pyramidal, slightly curved ; facets transversely deep 4-sulcate and 5-ridged, the ridges affecting the angles. The affinity of this species is close to E. adenoptera, as it comes under Boissier's sub-section ft Involucri appendices superiores {exteri- or es), bince, obliques, auriformes, duabus inferioribus multo majores. My specimens from the Isle of Pines differ much in -general habit among themselves and from the type, and the leaves are considerably less strongly serrate, yet they are good examples of the species. Euphorbia trichotoma Kth., H. B. K. , Nov. Gen. 2:60. The true form of the species very bushy and exuberantly leafy, making a compact mass. Involucres scarce, appearing near the ends of the branchlets.

In none of the specimens from these local- ities can be found the lobed leaves so frequent in the plants of other localities. In these the leaves are oblong-lanceolate 2.5-5 x l~2 cm- On account of the drifting of the sand the stems are always buried and seldom is any portion of the plant visible except now and then a leaf and flowering branch; the petioles of the stem leaves vary with the depth to which the stem is buried. When the burial of the leaves is of sufficient period to cause their death, rootlets are given off at their nodes, and the petiole is converted into a branch which forces its way upward through the sand, gives forth new leaves and finally flowers.

An infu- sion of this plant is used in domestic practice on this island in such cases of illness as are supposed to be due to a thick condition of the blood. It is called by the Indians "Ne-maax," or in the feminine gender, " X-ne-maax," " Monkey-tail," and by the Mexicans of Yucatan " Rabo de Mico," meaning the same, in allusion to the per- fect resemblance of the inflorescence to that appendage.

Com- mon on the smaller islands in Hamilton Bay, Bermuda (17); dry fields and roadside banks at Catano (151); south shores of Culebras Island (581), and at Guanica (687), Porto Rico; under coco trees at The Creek, Cayman Brae (1173), where it is known as " Verveen " and used as a purgative; and fields in the center of the island of Cozumel (1568). These specimens all agree with the descriptions of Stachy- tarpheta Indica and Jatnaicensis, while the following take on the char- acters given for S. strigosa Vahl. (= Valerianoides Jamaicense Indicum forma strigosum (Vahl.) O. Kuntze.), having the linear-acuminate setaceous bracts, which is the only character that in reality has any claim to permanence. The dentation of the calyx-lobes, sulcation of the rachis, and breadth of the bracts is very variable and too incon- stant to form even a varietal distinction; this, together with the fact that almost any dry field in the neighborhood of say Charlotte Ama- • lia, St. Thomas, or the Island of Grand Cayman will yield all the species known as Indica, Jamaicense and strigosa, would indicate that these are all merely forms of one species. Paget's, Bermuda (39), hillsides above Charlotte Amalia, St. Thomas (419), fields in the environs of San Domingo city (864), stony bed of a dry stream near Port Antonio, Jamaica (900), and fields along the Bodden Bay road, Grand Cayman (1340).
