ON THE OEGAN MOUNTAINS. 281 



the fall there grew abundantly the lovely Zygopetalum Mackaii, 

 the odoriferous Maxillaria picta, and Grobya Amherstice, with 

 its onion-like pseudo-bulbs. Early next morning the ascent was 

 continued. On tlie slope above the fall, but at a greater ele- 

 vation than I had attained the night before, I collected in moist 

 places an Eriocaulon, Drosera villosa, A. St. Hil., Surnia?mia 

 bicolor, Mart., a pretty little Gentianeous plant forming a new 

 genus {Hockinia montana, Gardn.), Cleistes montana, Gardn., 

 Luxemburgia ciliosa, Gardn., a white-flowered Chabrcea, a 

 large Senecio, and a tall purple-flowered Lobelia. In passing 

 through a wood above this I found plenty of my new Epiphyllum^ 

 several fine Begonias, Gesneras, and ferns. Emerging from 

 this wood, another steep ascent was again encountered, almost 

 entirely covered with a large Bromeliaceous plant, above which 

 rose a few fine shrubs, such as a very handsome scarlet-flowered 

 Salvia, aS'. Benthayniana, Gardn., Rondeletia longijlora, Cham, 

 et Schl., a pale rose-blossomed Gerardia, and several Veimonias 

 and Eupatoriums. Here also I found a magnificent sufiiuti- 

 cose plant belonging to the natural order of Gentians, which 

 proved to be a new species of Martins' new genus Prepusa {Pre- 

 pusa connata, Gardn. in Hook. ic. plant). Passing this place 

 we again entered a wooded tract, where I found abundance of 

 PromencBa xanthina, Lindl.,a few plants of Oncidium Forbesii, 

 and a tall yellow-flowered Senecio. Leaving this place, an open 

 slanting boggy tract was gained, in which I met with several 

 new ferns, such as a tall, shrubby, Proteaceous-like species of 

 Baccharis ( J3. platypoda, D. C.). a Vaccini?(?n, and an Andro- 

 meda, both in fruit, a Pleroma, a variety of Lavoisiera imbri- 

 cata, D. C., a Utricularia with fine purple flowers, and large 

 cordate leaves borne upon long petioles, a shrubby Hyptis, and 

 a Salvia with small purple flowers. We were now at an ele- 

 vation of about 5000 feet. On an open rocky place a little 

 further up grew great masses of a low gregarious species of 

 Vellozia, which unfortunately was just out of flower, and along 

 with it a few small Melastomaceous shrubs that were new to me, 

 several new fruticose Composites, and a small Gaylussacia. 

 Among these I found Siphocampylus duploserratus, Pohl., and 

 S. longipedunculatus, Pohl., together with two climbing species 

 of Valerian, a Ternstrcemia, a very small-leaved Ilex, a 

 Laurus, two species of Rhopala, Gaultheria ferruginea, Cham, 

 et Schl., a Weinmannia, and a Flotovia. The greatest eleva- 

 vation which I attained at this time was about 6000 feet, but 

 on another visit which I made to these mountains after my 

 return from the interior, I succeeded in reaching the summit, 

 and remained there nearly a week enriching my collections with
