be arranged under two types : — I. Areinonia type ; stamens super- 

 posed to the sepals, with or without a true corolla. Examples : Are- 

 monia, Agrimonia, Sanguisorba, Poterium. In Aremonia and Sangni- 

 sorba the stamens are simple ; in Agrimonia they are compound and 

 distinct ; and in Poterium, compound and confluent. II. Alchemilla 

 type ; stamens alternate with the sepals ; no true corolla. Examples : 

 — Alchemilla, Rubus, Rosa, Geum, Fragaria, &c. In Alchemilla the 

 stamens are simple. In Eubus and the others the stamens are com- 

 pound and confluent, with their terminal lobes developed as petaloid 

 staminodes (the petals ordinarily so called) analogous to the petaloid 

 staminodes forming the inner corolla of Bartonia, an ally of Ment- 

 zelia. 



Dr. Thomas Anderson reports on the state of the Cinchona planta- 

 tions at Darjeeling, in February, 1865. He states that the month 

 has been less favourable than January, as the cold, which has been 

 quite as great as in January, has been accompanied with a very dry 

 state of the atmosphere. Hail fell on the 3rd of the month and rain 

 on five days, but with the exception of the 25th and 26th of the month 

 only in slight showers, which did no benefit whatever to the Cinchona. 

 The slight increase in growth took place almost entirely during the 

 last five days of the month, with the exception of the lowest plantation, 

 where about the 17th the plants began to show the first symptoms of 

 the return of spring. At the first plantation (5,500 feet above the sea) 

 the temperature has been very low, causing the destruction of at least 

 three plants of Cinchona Pahudiana, and affecting a few of Cinchona 

 officinalis. At the second plantation (4,350 feet above the sea) hoar- 

 frost occurred in several nights in February, but no damage has been 

 done to any plants at this elevation. Observations on the temperature 

 of the air have been made with more or less regularity during the 

 month at the 3rd, 4th, and 5th plantations. At the fourth plantation 

 (2,550 feet above the sea) the maximum and minimum temperature in 

 the shade was recorded every twenty-four hours during the month. 

 The mean maximum temperature for the month at this elevation was 

 66°18, the mean minimum 47°93, and the monthly mean temperature 

 57°05. At the fifth, the lowest plantation (altitude 1,825 feet) fewer 

 observations were made, as the plantation was visited daily by the 

 person observing. The results from the detached observations there 

 give 7P56 as the mean maximum, and 47°77 as the mean minimum, 

 59 c 5 as the mean temperature of the month. 



The total number of plants, cuttings, and seedlings in the Govern- 

 ment plantation at Darjeeling, on 1st February, 1865, is as follows : — 

 Cinchona succirubra, 4,780 ; C. Calisaya, 23 ; C. micrantha, 944 ; C. 

 officinalis and vars., 19,329 ; C. Pahudiana, 5,092— total, 30,168. 



Dr. Moore, of Glasnevin, has recently visited the station in Gal- 

 way, for Nectinea intacta. He saw about 40 plants in the locality ; 

 they grew on a dry bank close to limestone. 



Dr. Dickson thinks that there are two marked varieties of Pingui- 

 cula vulgaris, in Scotland, distinguished by the size and form of their 

 leaves, as well as by their flowers. 



The Pitayo Cinchona has attracted attention of late, and a Report
