IN THE CINCHONA FORESTS 289 



Asclepiadea, 4. All milky twiners. This order, like the pre- 

 ceding, has its principal seat in the hot region, but is by no means 

 confined to it, for two or three slender Cynoctona are frequent 

 in the cooler parts of the Andes, trailing over the hedges of Cactus 

 and Agave. 



Solanacec?, 5. In this order, also, my collection contains a 

 very small proportion of the species existing in the Red Bark 

 woods. Shrubby Solana are almost endless, and two species rise 

 to trees. Two or three species of Cestrum also occur as slender 

 trees. 



Cordiacece, i. A Cordia, a stout sarmentose species, which 

 threads about among the trees up to a considerable height, though 

 it never actually twines. 



Convolvulacea. This order seems confined to a couple of 

 Iponiceae, both occurring very rarely. 



Myrsineu-', 2 (or perhaps 3). The most remarkable of all the 

 plants I gathered is a Myrsinea, though, as it grows only at from 

 5000 to 7000 feet, it barely touches the frontier of the Red Bark 

 region. It is an arbuscle of 8 to 10 feet, bearing a coma of large, 

 long, deep green coriaceous leaves, so that without flower it has 

 quite the aspect of a Grias; but above the leaves there is a mass, 

 the size of the human head, of densely packed panicles and 

 minute flowers, all of the same deep red colour. I have not 

 previously seen any Myrsinea at all resembling it in habit ; but 

 I have examined it sufficiently to state with confidence that it 

 belongs to this order, although probably to an undescribed genus. 



Labiatie, i. Besides the solitary species gathered, there exist 

 two species of Hyptis, one of them apparently //. Sihirco; 

 but this order is always scantily represented in the forest. In 

 cane-fields at San Antonio I saw a Stachys with small white 

 flowers. 



Verbenacd?, 2. One of them a prickly suffruticose Lantana. 

 threading among the bushes up to iS feet in height : the other a 

 woody twiner, with pretty waxy flowers, ilesh-co|nmvd externally, 

 but the limb purple within; it is prohabK ;i Citharexylon, allied 

 to ('. scandenS) llenth. (gathered on the Uaupcs). though the 

 h:ibit is totally different from the arborescent ( 'ithare\\ la \\ Inch 

 .urow in the cooler parts of the Amies. A Duranta uas noted at 

 San Antonio. A Stachytarpheta, which I t;ike to be S. Jamaicensis, 

 and is known in Peru and Ecuador as " Verbena," seems t,. |,.llo\\ 

 the steps of man in the Cordillera from near the plain up to 

 10,000 feet. At Limon it exists sparingly as a \\eed. Anol 

 species of the same genus, with very slender spikes and. small 

 lilac ilowers, abounds in open places. 



Gesneracea, 17. The abundance <>r this lamih i^ one of the 

 distinctive features of the Red Bark woods. One group, comprising 

 several speciex has a woody rhi/omc. ( r, , ping up the trees, and
