Mee te — Fco IUE 
OF THE MATTO GROSSO EXPEDITION, 1891-92. 269 
again lit up by the carnation flowers of Pavonia Rosa-sinensis, A. St.-Hil., and in its neigh- 
bourhood you may gather sweet-scented Kielmeyera ( K. amplexicaulis, S. Moore), Turnera 
chrysodoxa, S. Moore, tufted Eschynomene oroboides, Benth., and the straggling Manihot 
éripartita, Muell. Arg., var. vestita. The Labiate Hyptis effusa, S. Moore, remarkable for 
its long, capillary, almost invisible peduncles, rises to a man’s height. Melastomaces 
are common—-Miconias, Clidemia rubra, Mart., Tococa fornicaria Mart., the gorgeous 
Tibouchina stenocarpa, Cogn., &c.; Lippia lasiocalycina, Cham., Chaptalia integrifolia, 
Baker, Trivis ophiorrhiza, Gardn. (here, as in Eastern Brazil, a reputed alexipharmic), the 
fine heads of Chuquiraga chapadensis, S. Moore, the lowly Cuphea micrantha, H. B. K., 
Eupatorium megaphyllum, Baker, and masses of the common weed Stachytarpheta 
dichotoma, Vahl, will also be met with. Nor will a yellow-flowered Rubiacea ( Chomelia 
ribesiodes, Benth.) escape notice, if only from the peculiar habit shown by its inflor- 
escences of sheltering themselves from the broiling sun beneath a neighbouring leaf. 
The grasses, much the same as those met with in the low country, are frequently burnt 
by campo fires, but they suffer no permanent injury. Indeed, specimens belonging to 
this order, with charred outer leaf-sheaths, are common in herbaria, and most of my 
Chapada grasses show unequivocal signs of the action of fire. 
We reached the decayed village of Sant’ Anna da Chapada on the 25th and, the weather 
being superb, proceeded to sling our hammocks in a wood hard by. A little mountain 
stream, one of the feeders of Coxipo river, flows past the village, and in wet ground on its 
margin Eleocharis sulcata and E. ochreata, Nees, Rynchospora glauca, Vahl, and Mayaca 
Sellowiana, Kunth, were found, while Eragrostis Vahlii, Nees, and E. multipes, S. Moore, 
grew in plenty upon a bank skirting the stream. Other grasses of the place are Paspalum 
paniculatum, Linn., and P. conjugatum, Berg., Panicum horizontale, G. Mey., and Melinis 
minutiflora, Beauv. In shady places Ichnosipha concinnus, S. Moore, is to be seen, and 
you may collect Xylopia grandiflora, A. St.-Hil., Myrtaceæ (Myrcia ambigua, DC., and 
M. chapadensis, S. Moore), Miconias, a tree-fern, Psychotria tomentosa, Muell. Arg., &c., in 
the course of a short ramble. Noteworthy, too, is Banisteria constricta, Griseb., with 
its remarkable dimorphism. This shrub usually branches somewhat sparingly, and the 
branches bear large leaves; in places, however, the branches are much more numerous, 
and the leaves upon these are very small. We had, unfortunately, but two pack-mules, 
so that my supply of paper was soon exhausted, otherwise a larger collection could have 
been made upon this interesting plateau. We returned to Cuyabá on August 30th. 
I continued collecting at Cuyabá, and, although Manso appears to have secured a 
considerable number of specimens here, was not unsuccessful in finding new species. 
The small tree Anona Walkeri, S. Moore, growing on the city outskirts, and Hupatorium 
cuyabense, S. Moore, may be cited in instance. Here I found Copaifera elliptica, Mart., 
the Apocynacea, Anisolobus Zuccarinianus, Mart., Alibertia myrciifolia, K. Schum. (a 
common shrub), Bowdichia virgilioides, H. B. K., Hyptis (glauca, A. St.-Hil., crenata, 
Pohl, brunnescens, Pohl), and the elegant little Awratea Riedeliana, Engl., rare in 
herbaria, but here abundant. 
At Cuyabá we were joined by Lieut. Olaf Storm, of the Argentine Navy, prospective 
leader of the expedition, and by his brother Mr. John Storm, second in command, and it
